How much weed do you get from 1 seed

How to Produce a Ton of Weed with Only 1-4 Plants

Cannabis cultivation is legal in many parts of the world including several states in the USA. However, in many instances, growers are subjected to legal plant limits. For example, California (the state where I live) allows adults (21+) to grow up to 6 plants. In Canada, adults can legally grow up to 4 plants.

Legal plant count limits can make it harder to get big yields, especially if you’re also limited on space, but there are tricks and tactics to let you harvest huge amounts of bud from small grow spaces with just a few plants. In fact, it’s possible to produce over a pound of weed from 1-4 plants when you do it right.

Get big cannabis yields with just a few plants!

Pruning techniques like manifolding can force even a small plant to produce huge buds. This plant was less than 2 feet (0.6m) tall at harvest and produced 6.2 oz by itself.

Letting plants get bigger will increase your yields, especially when combined with pruning. These two cannabis plants are about 4 feet (1.2m) tall and produced 18.6 oz (over 1 lb) of weed between them!

This giant mass is actually made of only 4 plants trained to grow out over a screen.

Multi-pound harvest with just 4 plants!

It’s amazing what you can accomplish with a few plants. Let’s learn how to produce a ton of weed in your garden with 1-4 plants.

1.) Grow Bigger Plants

You can only yield so much from a small plant. Bigger plants can produce a lot more weed than small plants. Just make sure you don’t let plants get too big or your space quickly gets overgrown. Growing plants to the perfect size for your setup leads to the best harvest.

One of these clones got much bigger than the other. Although buds are similar in width, the bigger plant with longer buds produced higher yields overall. Letting a plant get big enough to completely fill your space can dramatically improve your final weights.

Main Idea: Don’t initiate the flowering stage until plants have reached 1/2 the final desired size.

Most strains about double in size after they start flowering. That means you should start 12/12 when plants are about half the final desired size. To maximize yields, you want plants that are as big as possible without overgrowing the space. It helps to calculate how tall plants can safely get in your grow space without being too close to your grow light. No matter the height you’re going for, try to create a nice wide plant canopy so the entire space under your grow light is filled with plants.

These two plants reached half the final desired size for this grow tent. At this point, initiate the flowering stage by giving plants a 12/12 light schedule.

A few weeks later, the plants have about doubled in size. This is known as the flowering stretch. Use this knowledge to grow plants that are the right size for your grow space.

  • No auto-flowering strains – The main idea behind this step is to control the length of the vegetative stage so plants get to the right size. Auto-flowering strains only spend a few weeks in the vegetative stage, and may not get big enough in time. Learn more about the best strains to grow in Step 4.
  • Use bigger pots – Bigger roots can support bigger plants. Plants in a small pot (under 2 gallons) tend to stay small while bigger pots (5-10 gallons) make it easier and faster to produce plants that are 3+ feet (1+ m) tall.
  • Consider coco or hydro – Plants grown in hydroponics (and to a lesser extent coco) tend to grow faster than soil plants. If you want to get big plants fast, hydro or coco may be a good way to go. Soil or super soil can still be great choices, but they may add to the total time to harvest.
  • Grow plants to optimal size – Initiate the flowering stage when plants are 1/2 the final desired size. This is done by using a timer to put grow lights on a 12/12 light schedule. On average, plants double in size after the switch to 12/12, though strains listed as “tall” or “short” may stretch more or less. Learn more about the flowering stretch.
  • Total plant coverage – Completely fill your space before you initiate the flowering stage.

2.) Train Plants to Grow Flat

You just learned about good plant coverage. This step takes that to the next level. In addition to making sure your entire grow area is filled with plants, you will increase yields even more if you train them to grow wide and flat (like a table) before you initiate the flowering stage. This is because the biggest buds grow close to the grow light while buds that are far from the light stay small. A flat canopy means you get many buds about the same distance away, and every single bud swells to a big size.

While plants are in the vegetative stage, bend branches down and tie them in place to maintain as flat and wide a canopy as possible. Try to make plants shaped like a table.

Main Idea: Train plants to grow flat and wide like a table in the vegetative stage.

  • Cut off the top of young plants – Cut off the top of young plants in the vegetative stage. Cutting off the top of a plant is often called “topping” in the cannabis growing world. Topping splits any stem into two, and a plant with two tops is easier to spread out to create flat plants than a plant with one main top
    • Beginner tip: Wait until the seedling has grown 6 sets of leaves. Cut off the top through the main stem above the 5th set of leaves (pictures below). Easy and simple, yet won’t stress plants. After being topped, your plant is easier to spread out and naturally grows more bushy and wide.

    Here’s an example of training plants to grow wide and flat for more bud sites and bigger yields.

    Cut off the top of a young plant right above the 5th set of leaves (“top” the seedling above the 5th node)

    When cutting through a stem, be careful not to damage the growing tips at the base of each leaf. These will become your two new stems.

    Topping splits the main stem into two. You can see the two new “main stems” on each side of the cut.

    Since you waited until the plant had several sets of leaves before cutting a small piece off the top, it will continue growing like nothing happened.

    As the plant grows, spread out the branches and cut off the top of any stem that’s getting bigger than the others. You don’t want your plant putting too much energy into any one branch.

    The plant was transplanted to a mini grow tent under an HLG 65 4000k LED grow light and given a week to adjust to the new environment.

    Bend over all the stems down and away from the center until it looks flat from the side

    I used plant twist tie to hook on to each branch and tie it down where I wanted. I attached the other end to the fabric pot.

    How to attach to the pot? You can use safety pins or binder clips but I think this is easier. Poke holes in the fabric using sharp pointy Fiskars pruning scissors and thread the twist tie through.

    Back to training. Here’s a top view. We’re trying to fill the entire tent with this plant.

    A few days later the plant has filled in nicely. Repeat the steps until you’ve filled your entire grow space.

    Initiate 12/12 when plants have complete coverage at the height you want. Look at all the bud sites on this 1 plant right as it starts flowering

    Here’s a side view. At this point, the only thing to do is water the plant and give it nutrients until harvest.

    At harvest, this plant was just over 18″ (46 cm) tall, yet yielded several ounces because it was trained to grow wide and flat. Talk about making the most out of one small plant!

    3.) Grow Light is Key to Yields!

    If you read step 1 and 2, you understand the value of plant coverage in your grow space. You’ve also learned how to produce plants that are the perfect height and shape to maximize yields.

    This step is about your grow light, which is the other most important aspect of your setup when it comes to yields.

    Main Idea: Pick a grow light that maximizes yields for your grow space.

    • Avoid fluorescent grow lights (CFLs and T5s) – If yields are a key factor for you, choose LEDs, HPS, or CMH/LEC grow lights. These are the most efficient grow lights for yields when it comes to growing cannabis. Fluorescent lights like T5s and CFLs produce excellent bud but get about half the yields per watt.
    • Expect 0.5-1 gram per watt – You can use wattage to estimate yields so you pick the right grow light for your goal. With LEDs, HPS, or CMH/LEC, you can typically expect about 0.5-1 gram per watt of actual power draw. So if you’re using a 400W HPS, you could expect to yields 200-400 grams. If an LED grow light uses 300W, you could expect 150-300 grams. You can yield more or less, and some specific grow light models are better than others, but that’s a good rule of thumb for an average grower.
    • Proper grow light distance to plants – Each grow light has an optimal distance it should be kept from plants. Too close and plants will burn, too far and yields are reduced. Most grow light models list the recommended light distance in their product details. If you’re not sure, check out our tutorial on light distance.
    • Good light coverage – Each grow light has an optimum amount of space it can cover (its recommended “light footprint”). If light doesn’t reach your plants on the edges, those plants will produce poor yields For example, if you have a 2’x3′ (or 0.5mx1m) grow space, get a light that’s made for that size space. Luckily, this is another detail that’s usually listed in the description when you buy a grow light.

    Maximize yields with the right grow light for your space

    Check out examples of yields to expect for 3 popular cannabis grow lights I recommend for indoor growers.

    Set and Go – 100W Quantum Board (LED Grow Light)

    • Grow space: 2’x2′ grow space
    • Heat: Fixture gets hot but will not warm up the room
    • Average Yields – 1.5 – 3.5 ounces
    • Bud Quality: Potent and pretty with great effects, but buds may be airy
    • Recommended model: HLG 100 LED Grow Light
        is best for seedlings, clones, and the vegetative stage is best for the flowering stage
      • both work from seed to harvest, but 3000k produces higher yields

      If you want to start small, this light lets you hang up a grow light and start growing decent amounts of high-quality weed in a small space. Flimsy but effective. It barely affects the electricity bill and doesn’t make much heat. Also an excellent choice for seedlings and clones.

      HLG 100 should be kept about 10″ away from the tops of plants

      3 plants grown with the HLG 100 using the techniques above – 5.5 oz

      Great Yields Without Much Heat – 300W Quantum Board (LED Grow Light)

      • Grow space: 2’x4′ or 3’x3′ grow space
      • Heat: Warms up a room by a few degrees
      • Average Yields – 5-10 ounces
      • Bud Quality- Dense, potent, sparkly nugs
      • Recommended models: Electric Sky 300 and HLG 300 R-Spec
      • Example setup with this type of light

      For this size grow light, I’ve had the best results with HLG and Electric Sky. The HLG lights cost less and feel flimsy, but I love that they don’t weigh much and are easy to hang. Electric Sky LEDs are expensive and industrial quality, but also heavy and difficult to hang. Both of these lights produce some of the nicest bud I’ve grown, but so far Electric Sky has produced the best yields.

      3 plants grown with the Electric Sky 300 using the techniques listed above – 11.1 oz

      5 plants grown with the HLG 300 R-Spec using above techniques – 9.34 oz

      Big Producer – 315W CMH (sometimes called LEC)

      • Grow space: 3’x3′ grow space
      • Heat: Burning hot bulb raises the temperature of a room by several degrees
      • Average Yields: 5-12 ounces (though I’ve yielded over a pound before)
      • Bud Quality – Intense smells and unbelievable trichome production (get the most glitter by using the 4200k Philips or 4100k Eye Hortilux bulb in the flowering stage)
      • See an example setup with a 315 CMH

      4 plants grown under a 315 LEC grow light using the above techniques – 12.57 oz

      4.) Choose the Right Genetics (plus example strains)

      If yields are a consideration, pay close attention to genetics. You can greatly increase yields by choosing a strain that is known to yield more than average.

      • Photoperiod strains only – To follow this tutorial, you need to be able to control the length of the vegetative stage. Photoperiod plants give you total control because they won’t start flowering until you initiate a 12/12 light schedule. Most cannabis strains are photoperiod strains, so unless you buy “auto-flowering” seeds, you’re good to go.
      • High-yielding – Some strains can yield 2-3x as much as other strains in the exact same grow space and conditions. It’s astounding how big of a difference genetics makes to yields.
      • Avoid “short” strains – Short strains tend to yield less because plants are smaller.

      Example strains that are heavy-yielders

      This single Wonder Woman plant produced 12.57 oz of dense buds under 300W

      Each branch produced over an ounce of weed after being dried, and every bud was rock hard.

      5.) Advanced Techniques

      If you only follow the steps above, you can produce bountiful yields with just a few plants. But some growers want to maximize their yields even more. In that case, this section is for you.

      These techniques require a bit more work and know-how, but they can produce incredibly high yielding plants indoors.

        (Screen of Green) or Fluxing

      ScrOG (screen of green) means using a screen or netting to train plants to grow flat before flowering.

      Manifolding or Fluxing are similar techniques with the goal of creating plants where all the branches meet at one part of a plant (the “manifold”). These techniques require extra time in the vegetative stage, but reward you with huge symmetrical buds. Plus these techniques are super fun!

      With manifolding or fluxing, young plants are cut up in the vegetative stage so that all branches come from one main “manifold” on the main stem.

      The base of a “manifolded” plant

      Fluxing is a different take on manifolding, but follows the same essential principles of splitting the main stem and creating a symmetrical plant structure

      When followed step-by-step, these techniques produce outstanding harvests on every plant

      A grower named “nugbuckets” designed and popularized the manifolding technique (though he called it “main-lining” at the time) to maximize yields per plant. Here’s one of the manifolded plants from his original tutorial. A huge thank you to nugbuckets for sharing your knowledge with the home growing community!

      Now you are armed with the knowledge to produce tons of marijuana even if you have plant limits. It’s time to grow the yields you want!

      How much weed can you get from growing one plant?

      As states legalize weed and the plant becomes more accepted, more people are trying out their green thumbs by growing their own weed at home. Most states with legal weed allow one person to grow six plants at their residence and an entire household to grow 12 plants. Some allow less, and some allow more.

      (To see how many plants your state allows you to grow at home, check out this table).

      But how much actual weed is that in dried buds that you can smoke? An ounce? A pound? Two pounds? The tricky thing is, all weed plants aren’t the same size, and many factors affect how big a plant will get and how dense its buds become.

      We’ll go through those factors and talk a little bit about the harvest process to estimate how much weed you can get from one plant.

      How much bud from one weed plant?

      Many factors affect how big a plant gets, but generally speaking, if you are growing a healthy plant, you can expect these yields from one weed plant:

      • Outdoor plant: ½ pound of buds, or about 224g
      • Indoor plant: ¼ pound of buds, or about 112g

      Note that these are estimates. When growing outdoors, plants can usually get massive because they aren’t restricted to space—it’s not uncommon to get closer to a pound a plant or more.

      When growing indoors, you’re often limited by space—a plant can’t get as big in a grow tent as in a big, open basement. You’re also limited by how powerful your grow light is. For example, Leafly editor David Downs harvested 150g from one indoor plant with one 200W Black Dog LED light. The company said that light maxes out around a half-pound of buds, or 224g.

      Also, these estimates are for healthy plants. If a plant becomes nutrient-deficient, gets bugs or mold, or doesn’t receive enough light, expect a lot less.

      How long will one plant’s worth of bud last you?

      However big your plant gets, you’ll likely have more flower than you know what to do with. Many people will save a certain amount of flower for smoking, and make edibles, concentrates, and other weed products with the rest of their harvest.

      Consider how much weed you smoke in a day, week, or month. For reference, a gram is about two medium joints or 3-4 bowls. Do you smoke a gram a day or a week? Two grams a day or a week?

      Using the above yield estimate of ¼ lb., or 112 grams, for one medium-to-large-sized indoor plant, if you smoke one gram a day, that one plant would last you 112 days, or just under four months! Two grams a day would last you just under two months, and half a gram a day—or an eighth a week—would last you eight months.

      This will help give you a sense of how many plants you should grow. If you’re growing indoors, you can grow one plant at a time, harvest it, and start another, keeping a continuous cycle of growing.

      If growing outdoors, you may only get one harvest a year. Remember, check out how many plants you can legally grow in your state here.

      Factors that determine a weed plant’s yield

      The amount of dried buds you harvest from a weed plant is called its yield, just like any crop, such as corn, wheat, fruit, etc. Ideally, when growing weed, you want high yields and high-quality buds. Getting both takes a little practice.

      A weed plant will lose about 75% of its weight to moisture loss and trimming after being cut down. A considerable amount of moisture leaves the plant during the drying process, and trimming removes all the stems, branches, fan leaves, and trim from the plant.

      So if you weigh a freshly cut plant at three pounds, don’t get too excited—you’ll likely get ¾ lb. of finished buds (which is still a lot of weed).

      A big plant doesn’t necessarily mean big yields, as buds can be thin and wispy. A medium-sized plant with quality, dense nugs could yield more than a six-foot tree. Also, if growing multiple plants, they can grow over each other and shade one other out, reducing yields. Make sure to give plants plenty of space.

      Some major factors that contribute to a weed plant’s yield include:

      • Strain/genetics
      • Grow duration
      • Light
      • Climate
      • Soil type/amount


      Certain weed strains grow big or tall or are high-yielders simply because of their genetics. Traditionally, indicas grow short and stout, and sativas grow tall and lanky. That’s not always true across the board, but it is a good rule of thumb.

      For example, Lemon Skunk is famously a tall, lanky strain, so you’re likely to get high yields from it. Blue Dream and Chemdog are also known for their high yields.

      Aside from its candy-like flavor, Runtz gets its name because its buds grow small, like the runt of the litter. It might be a low-yielder, but you’ll usually get high-quality buds.

      Growth duration

      How long you allow a plant to grow, or the length of time from seed germination to harvest, is one of the most significant factors determining weed yield. If you start growing seeds in March rather than May, those plants will have two extra months to get big.

      When growing outdoors, the local climate is the main determining factor of when you can put seeds in the ground. Some regions are too cold to put plants outside until May, but you can start growing plants indoors with the right setup.

      Some regions get rain early in the fall, so you’ll want to grow plants that are ready to harvest by the beginning of October. In tropical climates, you can practically grow weed outdoors all year round.

      When growing indoors, growth duration is determined by how much space you have to work with. If you have a spacious basement or shed, you can let plants grow for months and get as big as you want before forcing them to flower. If space is tight, like in a grow tent or other small areas, you may only be able to let your plants get a few feet tall.


      How much light a plant receives is highly variable. When growing outside, it all depends on where a plant is located to receive the most light throughout the entire season. Weed plants like full sun—at least six hours of direct sunlight every day. If a plant is in the shade or gets shaded as the light changes throughout the season, it can affect yields.

      Indoors, it depends on how powerful your light is. A small 200W LED is great for a small grow tent, but you’ll need something bigger for a bigger space, which also means a more expensive light.

      Be sure to prune your plants to remove dead leaves and buds, and branches that won’t turn into sizable buds. Clearing out plant matter will allow the quality buds to get more light.


      Weed typically likes warm, temperate climates—think of Northern California’s Emerald Triangle region—but certain strains thrive in different temperatures. Traditionally, indicas like cold, dry climates and sativas like warm, humid climates.

      Sudden extreme changes in temperature can affect a plant’s growth and yields, such as a sudden cold snap, which can slow a plant’s growth, or a heatwave, which can dry out a plant.

      Soil type/amount

      Different soils have different nutrient levels and some nutrients can promote plant growth. You can also add nutrients to soil or water to help plants grow big and strong.

      Additionally, if growing in containers, the size of the container, or the amount of soil the plant’s roots have, will affect the size of a plant. Growing in too small of a pot can stunt a plant’s growth.

      Check out guidelines on how big of a container you need for different sized plants here.

      Growing directly in the ground will give your plant’s roots plenty of space, but you may need to add nutrients depending on the soil’s quality.

      How Much Weed Does One Plant Produce?

      “How can I grow as much weed as possible?” You know that’s what’s on your mind when you ask or wonder about plant yield. Old and new marijuana growers (and scientists and politicians ) alike want to know how to get the highest yield per plant and per grow. Planning and practice can make a huge difference– especially when you are only growing one plant!

      But, ultimately let’s not forget that the cannabis plant is a sentient being. She’s alive! Her growth is dependent on many factors and the same plant can produce a pound in one situation and a couple grams in another. Below we will detail the known factors that impact yield and potency, discuss where things can go wrong, and where things can grow right.

      What is yield? (wet vs. dry yield)

      Yield is the amount of weed you get when you harvest your marijuana plants. This is only the buds themselves, removed from the stems. This is most often measured once your marijuana buds are dried and trimmed. This is generally measured in grams, ounces, and pounds. The “lid” is not a used measurement anymore.

      One of the most know measurements currently is an 1/8th (of an ounce) which is 3.5 grams. This is commonly found in dispensaries as well as something one might purchase from their friendly neighborhood weed guy. In this picture below, only two perfectly grown and cured buds were needed to reach this weight!

      Wet and dry cannabis does not weigh the same.

      Immediately upon harvesting, your buds will be quite heavy. That’s because, like humans, freshly harvested cannabis flowers are 75 – 80% water by weight. Once dried and cured, the actual harvest you get is about ¼ of the wet weight. So, if your harvest weighs out at an ounce at first cut, when it’s all said and done, you will have a quarter ounce of homegrown weed to smoke.

      To estimate your dry yield from your wet yield, just multiply the wet yield by 0.25 to get an idea of what you’ll have to share with your friends (or stash away for yourself)!

      This varies slightly depending on if you grew a sativa-dominant or an indica-dominant strain. Sativas are notoriously more airy so if you weigh your sativa harvest wet, you will get 20 – 22% dry. Indicas tend to be a bit chunkier so if you weigh your indica harvest wet, you will get 22 – 25% dry.

      ​​Yield vs. Potency

      Yield is an important factor to consider because cannabis is an annual crop; there’s only one harvest per plant. After harvest, the plant is dead and returns to compost. Yield is the weight of the buds that you harvest. Yield should not be confused with the potency of these hefty green nuggets. Potency is the strength of the cannabinoids found in the trichomes on your cannabis buds.

      In other words, you can have a high yield of low potency buds. Or you can have a low yield of high potency buds. In a perfect world, you’d get a high yield of high potency buds and we are going to discuss how to make that happen!

      What to do to increase your weed plant’s yield?

      Let’s get the most out of your homegrown medical (and recreational) marijuana. Best plant performance and yield are the result of growing the right strains under the right conditions. The most important factors being: light, plant density, fertilizer, temperature, duration of the flowering growth stage, and plant variety. In sum, the TLDR version is:
      blast as much light as you can afford, grow less plants to fill your space appropriately, feed your plants just enough but not too much, keep the space not too hot and not too cold, don’t harvest early, and don’t buy shit genetics
      (bag seed gamblers are included!)

      Light to Increase Weed Plant High Yield

      The yield from an indoor-grown cannabis plant largely depends on the light the plant receives. Cannabis plants, being photosynthesizers, receive all their energy to function from light.

      The type, quality, and amount of light you provide your marijuana plant directly influences yield and should not be taken lightly (see what we did there?)

      Sunlight is the most powerful light us earthlings have access to, so if you are able to give your plant direct sunlight, do it! Sunshine is also free, and that is a big plus. The only downside is that we cannot control cloudy or rainy days and winter makes it challenging to grow with the limited amount of sunlight (the freezing temperatures also don’t help).

      Moving to an indoor grow environment, w hen it comes to lighting fixtures, it does not benefit you to get the cheaper option. And we know how challenging it is to pick the right light- – there’s so many options out there! (incandescent, CFL, HPS, LEDs)

      We do not encourage growers to use incandescent light bulbs when growing indoors. To get enough energy for your plant, the bulb would put off too much heat and not be fun to see on your electric bill. CFL bulbs are equally useless. Stick to new technology to protect your plants and your wallet.

      While HPS light fixtures are historically the choice for those who want to maximize their indoor cannabis crop harvest, they are slowly fading out from commonplace. An experienced grower can expect to harvest a gram of weed from each watt of HPS light provided to the plant. This means that if the light is a 400-watt HPS bulb, then 400 grams of weed could potentially be harvested. However, LED light technology is getting more advanced. LEDs are: 1) cheaper to run than HPS and 2) run cooler than HPS which also lowers the cost of air conditioning and 3) reduces the likelihood of burning your plants with too much light.

      When choosing an LED light fixture for your weed plants you are up against a surplus of options and information.

      The most important metrics to look for in a lighting fixture are PPF, PPFD, and energy usage/efficacy . If none of these are present, you may want to look at a different fixture.

      PPF, PPFD, and photon efficiency are measurements related to PAR. PAR is photosynthetic active radiation. PAR is not a unit of measurement but instead defines the type of light needed to support photosynthesis.

      PPF is how much PAR a lighting system produces each second. This is not often listed as it does not show how much of the measured light actually lands on your plants but is a useful metric to calculate how capable a light fixture is at creating PAR.

      PPFD (photosynthetic photon flux density) is the measurement of how much PAR actually arrives at your plant. This is a spot measurement and is typically highest at the center point beneath the light and decreases as light ripples outwardly. This changes with the distance away from the plant. Ideally, the higher the better but a single measurement won’t tell you much– you want the average taken from many measurements throughout the coverage area.

      Photon efficacy is a way of defining how good a lighting fixture is at converting the electrical energy into PAR light that your plant can actually consume. This is not often listed in the spec sheet for most lights. Instead, most light manufacturers list the wattage, either total electrical watts or watts per square foot. Knowing the wattage is good to budget the main cost of your indoor cannabis grow. But the wattage doesn’t give the best information about the quality of light as watts are a measurement of the energy coming into the light fixture (from your electric bill) where photon efficacy is how good the light is at giving your plant energy.

      We suggest paying attention to whether or not the company you want to buy a light from lists the actual wattage or the watt equivalent. (Hint: if they are only disclosing the watt equivalent, the light is most likely not strong enough for cannabis.)

      LED wattage and incandescent wattage aren’t the same.

      Many LEDs are marketed with their “incandescent equivalent” wattage, referring to the brightness of the LED. For example, a 10 watt LED may say “75 watts” on the package and in fine print say that the brightness is equivalent to a 75 watt incandescent. But for growing cannabis, you’re going to want an actual real 75 watts (or higher!) from your LED lamp .

      Can I give my weed plant too much light?

      The answer in fancy, science talk:

      Effectively, within the range of practical indoor PPFD levels—the more light that is provided, the proportionally higher the increase in yield will be. Therefore, the question of the optimum LI [light intensity] may be reduced to more practical functions of economics and infrastructure limitations: basically, how much lighting capacity can a grower afford to install and run? – Victoria Rodriguez-Morrison, David Llewellyn , and Youbin Zheng

      In plain English:

      No, not really! For a vegging photoperiod cannabis plant, you will want to give her a minimum of 18 hours of light a day– some give 20 hours or even keep the lights on 24/7. We know that a lot of good growth happens during the dark period when the cannabis plant has time to rest so we suggest either a 18/6 or 20/4 light cycle for photoperiod cannabis in the vegetative stage.

      Same goes with autoflowering cannabis, with an autoflower seed indoors, you’ll want to give it 20 hours light / 4 hours darkness each day.

      When it comes to using light to maximize yield, maximize the light intensity to meet your budget.

      Grow Less Cannabis Plants to Get More Weed

      In some ways you may think that if you pop more marijuana seeds or get more clones that you will get a bigger harvest in the end. This is not always true.

      Each cannabis plant wants her own space. Planting more than one seed in a pot leads to competition between plants for the shared nutrients and reduced yields. As seen in this photo below where two seedlings starved each other and both ended up dwarfed:

      The size of the container that you grow your pot in matters, too. Outdoor plants have the potential of reaching extreme oak tree size when planted directly in good soil (which can be hard to find) and allowed to flourish in an open, sunny space. Indoor cannabis plants, become much like a goldfish in either a fishbowl or an aquarium or an ocean, you will grow a different size plant from the Mini Complete Pot Grow Kit (1/2 Gallon) to the Medium Complete Pot Grow Kit (5 gallon) or the Large Complete Pot Grow Kit (35 gallon) . The bigger pot, the bigger plant (and the more pot).

      Growing in a grow tent, consider the total space as well as the size of your containers. It may sound like a good idea to pack a small 24’’ x 48’’ x 60’’ tent with as many pots as possible but this will limit the canopy space for your plants to fill. Best to give each pot space for the plant to fill out.

      Growing less plants means:

      1. A longer vegetative stage. This means bigger plants. Bigger plants have bigger harvests and higher yield. When growing photoperiod cannabis indoors, it is time to transition your tent to flower when the tips of the leaves of each plant begin to touch. More plants touch each other faster.
      2. Less plants to manage! You know each one personally and can tell when even the slightest thing is off which means you can catch pests and diseases before they become a major problem. This also means that you will have more time for defoliation and advanced pruning techniques to maximize your yield!

      In the same space with a 600 watt HPS lamp, you can either get 37.5 grams from 16 plants, 150 grams from four plants, or a pound from one single plant! Don’t compromise on plant density; the more space you give a single plant, the more she can blossom.

      Best Grow Mediums to Maximize Harvest

      Yield can also vary based on the particular grow medium you use. It has been clearly documented that using hydroponics to grow marijuana can result in 20 percent more yield compared to using soil indoors.

      Hydroponics increases yield because it is the most efficient way to feed plants. The grower supplies all the nutrients that the plant would naturally need to find for herself in the soil.

      But, hydroponic systems are also 1) more expensive to set up and run, 2) can take time (like several runs) to dial in a nutrient feeding schedule and 3) can go wrong if your plants are fed too much.

      At the simplest level, fertilizers come in varying NPK (Nitrogen, Phosphorous, and Potassium) formulations. Fertilizers that are richer in nitrogen are ideal for the vegetative phase, and those richer in potassium are better suited to the flowering phase. Growing hydroponically you need to know which nutrients your cannabis plants need during their different stages of growth and have that ready.

      Whether you opt for organic, inorganic, or a mixture of the two is more of a personal decision. The important thing is that your marijuana plants receive enough nutrients to give you a higher yield per plant, but never too much. Unlike light intensity, there is a sweet spot for nutrients when it comes to growing marijuana. Too much of a good thing can negatively impact your plants. Unfortunately, finding the right balance between enough nutrients and excess nutrition usually comes with experience.

      Soil grown marijuana can pull down some epic yields as well. But not all soils are created equal. For example, one person growing marijuana in loam soil may have a richer harvest since loam soil is easy for the roots to penetrate. On the other hand, clay soil could lead to a dismal yield since it doesn’t easily drain and can be quite compact, making it difficult for cannabis roots to grow.

      That’s why a Pot for Pot specially formulated our Superb Soil to contain just the right amount of nutrients to maximize cannabis growth. With a Pot for Pot kits, there’s no need to add additional fertilizer because their soil has everything your plant needs from seed to harvest . It isn’t just easy to use, it’s optimized for marijuana growth.

      Our complete grow kits include everything you need to go from seed to your very own supply of high grade medical cannabis.
