Hydroponic Seed Starting 101: A Primer for Beginners
Starting your seeds hydroponically has many benefits, but many people are unsure how to go about it. Shannon McKee gives us a primer on the basics of starting your own seeds to expand on what you’re currently growing.
Many people skip starting their own seeds because of the time and effort to get them started, but there are some great reasons to start your own seeds hydroponically. It’s so much easier to just go to the store to pick up some seedlings to pop into your system and get growing, right? Well, store-bought seedlings do have some downsides that can be avoided if you start your own.
The first is that you’re limited to what you can grow in your system. You have to choose from the options available at the store. However, if you start your own seeds, you can grow anything. This means you can grow your favorite heirlooms or even rare plants that aren’t found at many nurseries.
Adding seeds to your hydroponic system means that they won’t go through any trauma or root damage from being transplanted into your system. This process may also introduce diseases or bugs into your hydroponic system from the store.
Also, you get the satisfaction of growing a plant from a tiny seed rather than just picking up a seedling. Plus, a packet of seeds can grow a number of plants for just a few bucks, whereas the cost of only one seedling can be the same amount.
Seeds are also more cost-effective than buying one or two seedlings in the long run, as you can save some for the following year. The germination rate can decrease over time, but often, you can still get quite a few to sprout over the years until you have to buy your next seed packet.
What You Need to Start Seeds in a Hydroponic System
The first time you start your own seeds for your hydroponic system may be a bit more expensive at the beginning because you need to buy more materials than in future years. Seeds need water, light, oxygen, and heat to grow. You really don’t need anything too special to grow your own seeds.
You can use a grow tray with a dome for your own miniature greenhouse to create an ideal environment. If you’ll be growing your seeds in an area that is cooler, you may want to invest in a heating mat that goes underneath the grow tray to keep it warm as this is a necessary condition for sprouting to occur. Light is good to have as well as this will help your seeds sprout.
Inside of your grow tray, it can be beneficial to use a pot that works for your seeds and their future as seedlings in your hydroponic set-up. You’ll want to use starter cubes, such as those made of stonewool (rockwool). The key here is to use something that can withstand being immersed in water without dissolving, as it could clog up your system after transplanting.
Step by Step Instructions for Sprouting Seeds in a Hydroponic System
- The first thing that you’ll want to do is to soak your starter cubes in clean water for about an hour. After they’ve been given a chance to soak, put a few seeds into the cube’s hole. You’ll want to add several just in case you have some seeds that don’t germinate. Once they sprout, you can thin out the weaker plants to allow the strongest to grow.
- Prepare your grow tray with about an inch of clean water or nutrient solution that is at half strength. Arrange the light source and heating mat as needed. You can keep the lid on to keep the heat and moisture in the tray.
- Put these planted cubes into the grow tray and add water or the half strength nutrient solution as the level goes down in the grow tray.
- After about four days, you’ll start to see some sprouts emerging.
Some people prefer to use a Ziploc bag, rather than a grow tray, when trying to get the seeds to germinate as it functions like a greenhouse. Seal the bag with a little bit of air and put it in a dark place for about four days to get the seeds sprouted. Then, you can put the starter cubes with sprouted seeds into the grow tray.
Step by Step Instructions on Transplanting
Keep your tiny seedlings growing strong with your hydroponic nutrient solution. Once they’ve gotten bigger, you don’t have to make the nutrient solution half strength.
You’ll start to see the seedlings’ roots coming out of the bottom of the cube, and this is the sign you’ve been waiting for, as it means you can start transplanting. This can take about two to four weeks depending on what plants you’re growing.
Clear up a spot in your hydroponic system’s growing media for the seedling – cube and all. Gently transfer the starter cube into your growing media, and cover it gently.
Give the root system a chance to naturally seek out the water and nutrients in your system by top watering it for a few days to give it a chance to grow the root system.
Voila! You grew your own seedlings into a strong plant for your hydroponic system. Depending on the type of plant, you’ll be able to get your first harvest about four to eight weeks from the time you transplanted your seedlings.
Cut out the dependency of only being able to grow the types of plants that are available as seedlings at your favorite gardening store. Take a little extra time to nurture your seeds so that they become strong seedlings ready to transplant into your system. You’ll be able to take pride in your efforts with how healthy your plants are and your overall system’s health.
How To Quickly And Successfully Germinate Cannabis Seeds
All cannabis plants, whether tall and lanky Sativa trees or compact and sturdy Indica bushes, start from a single weed seed. This tiny brown nut contains everything necessary to eventually yield hundreds or even thousands of grams of potent buds! However, to reach that point, it’s important to place the seed in a special environment that will trigger life inside it, crack the shell open, and let the roots and stalk out.
In this article, we’ll be explaining how to germinate cannabis seeds and tell you about the best ways to do it. Before we start though, it’s important to know what environment cannabis seeds are most likely to pop in. Since in nature, they germinate in spring, logically, you want to put them in conditions that mimic fertile ground in spring – think plenty of moisture, little light, and mildly warm temperatures of around 18-22 C (64-71 F). Now, you’re ready to learn about the best ways to germinate cannabis seeds. Let’s dive right in!
Main Methods Of Cannabis Seed Germination
The following three methods have proved to be some of the easiest as well as the most effective. This means each of them is a great way to help your cannabis seed to sprout.
Germinating Cannabis Seeds In Soil
When spread naturally, marijuana seeds germinate directly in soil. So, why not recreate the natural process? This method is great for beginners because of how few steps it requires. All you need to do is make a 1.5-2cm (0.5-1 inch)-deep hole in the soil, place your seed in it, and lightly cover it with more soil. Then, water the spot above the seed and keep an eye on it to make sure the area stays moist most of the time. It’s also a good idea to cover your starting pot loosely with a plastic bag or a wrap to keep the environment humid and warm until the seedling shows up from the soil. This method is preferred by many because it eliminates the stress of transplantation that, at times, can be too tough on fragile seedlings.
Cannabis Strains For Beginners
Germinating Weed Seeds In Water
If you’re not ready to get your hands dirty just yet, it’s fine! Some growers start their seeds in a glass of water. This method is easy and quite effective. Practice shows that germinating in water normally makes around 90% of weed seeds pop. This method is pretty self-explanatory – all you need to do is place your cannabis seeds in a glass of fresh water away from light. Usually, the nuts crack open on the second day. For older seeds, however, the process may take up to 7 days, which is also fine. After the taproot shows, the seed is ready to be planted. Some growers wait for the seeds to drown (about 24 hours in), then transfer them to a wet paper towel – the method we’ll be explaining next.
How To Germinate Marijuana Seeds In A Paper Towel
This next method is a true classic that’s been shared grower to grower for generations. It’s also pretty simple and has everything you need to maintain the perfect environment for cannabis seeds to pop. To use this method of germination, place your seeds on a clean paper towel, fold it over them, and spray the towel lightly with water. After that, put the moist towel on one plate and cover it with a second plate to keep the seeds in the dark and not let the moisture evaporate. That’s pretty much it! This method can also be modified and improved upon. For example, instead of a paper towel, you can use two cotton pads for each of the seeds – these will be easier to open when it comes to removing the seed. Instead of plates, you can also place your seeds in an airtight container or ziplock bag to ensure the moisture stays in the towel/cotton pads.
Easy-To-Grow Cannabis Strains
How To Germinate Cannabis Seeds In Cotton Wool
Start with making a layer of cotton wool moist but not dripping wet, so that the excess water won’t suffocate the seeds. Then place your seeds on top, cover them with another layer (also moist), and put everything in a dark place.
Make sure the cotton wool is covered and won’t dry out while the seeds germinate.
The difficulty with germinating cannabis seeds in cotton wool is that the emerging roots may get entangled in it. For this reason, it’s better to use cotton pads in which cotton is more compacted and there is less fiber sticking out.
How To Germinate Autoflower Seeds
Cannabis is cannabis, and germinating autoflower seeds is exactly the same as any other variety. Just make sure to use the most effective technique because with autos you don’t want to lose any time at any stage, including germination.
Also, autoflower growers often choose the straight-into-the-final-pot method of germination to spare their precious babies any shock of transplanting.
Alternative Methods Of Cannabis Seeds’ Germination
Now let’s move to the more modern methods of cannabis seeds germination. These aren’t necessarily better in terms of germination rate, but still have some pros as well as cons that we find important to explain.
Germinating Cannabis Seeds In Peat Pellets Or Starter Cubes
If you want to give your seeds special treatment and make them feel loved from the very first day in your grow op, you might want to get your hands on peat pellets or starter cubes. So, how do you germinate marijuana seeds in rapid rooters, peat pellets, and starter cubes? These are all individual plugs of peat or a special seed starter mix that are incredibly easy to use and don’t leave much room for error. In the case of peat pellets (you may also know them as jiffy pellets), all you need to do is soak them in warm water, which will make the pellets expand. Then, squeeze the excess moisture out and place your seed (pointy side down) inside the pellet. Starter cubes and rapid rooters don’t require squeezing, but whatever you choose, you need to make sure your medium is slightly moist at all times. One of the greatest advantages of this method is that the seed germinates in complete peace and doesn’t need to be transferred from the pellet/starter cube/rapid rooter. After the seedling is out, just plant it into the soil together with what you were germinating the seed in.
Fast Flowering Cannabis Seeds
If you’re wondering how to germinate marijuana seeds for hydroponics, peat pellets, unlike other methods from this article, aren’t suitable for hydroponic setups. However, the rest of the techniques we’ll be discussing can be used for both soil and soilless media.
Germinating Cannabis Seeds In Rockwool Cubes
If you’re growing your seeds in a hydroponic setup, you might want to look into rockwool cubes for germination. As a material, rockwool is inert, cheap, and easy to find. Fans of hydroponic grows often choose rockwool for its mold-resistant qualities. The process of germination in rockwool cubes is the same as described in the previous method: simply place a seed inside a cube, water it, and keep it moist until the seedling is out.
Even though many growers prefer using rockwool for germination of their cannabis seeds, this method has quite a few drawbacks. First of all, the pH of new rockwool is not suited for cannabis seeds. It’s far too high and needs to be lowered before use. That’s why rockwool requires soaking overnight in pH-ed water and properly rinsed afterward. The second drawback of using rockwool for germination is that it’s a synthetic material that’s bad for both your health and the environment. When working with rockwool, it’s advised to use gloves and protective masks, because little pieces of the material can easily get into your mouth, eyes, and even end up in your lungs. Lastly, germination rates for seeds placed in rockwool cubes aren’t that great either – you can wait for your seeds to pop for weeks without any result.
Cannabis seed germination methods comparison table
In this article, we’ve covered five main germination methods. To sum everything up, here’s a comparison chart that can help you decide on how to germinate your marijuana seeds.
How To Germinate Cannabis Seeds For Hydroponics
DWC systems have seen a huge rise in popularity among home growers, making the question of germinating cannabis seeds for hydroponics extremely relevant. Is it any different? Not really, because the basics stay the same. You can still start with the paper towel method or a glass of water. However, we suggest using either starter cubes or rockwool when germinating cannabis seeds for hydroponics, as this will take the risk of damaging the sprouts to the minimum.
Here’s what you’ll need to do:
- Soak your starter cubes or rockwool pieces in clean, pH-neutral water for an hour.
- Place a seed inside the cube.
- Put the starter cubes/rockwool cubes with seeds in them inside the grow tray.
- Fill the bottom of the grow tray with an inch (2.5cm) of clean water or a very light nutrient solution.
- Dial in the temperature (20-30C/69-89F) and humidity levels (80-90%).
- Keep the lid on for conditions close to a greenhouse.
That’s it! After a couple of days, you’ll see your sprouts emerging.
How Long Does It Take For Marijuana Seeds To Germinate?
Your preferred method won’t make much difference in how long it takes for marijuana seeds to germinate. What actually matters when it comes to germinating cannabis seeds quickly is the quality of the seeds, their genetics, and how old they are. Normally, fresh seeds of good quality will never take more than 5 days to show taproot. However, if your seeds have been waiting for their hour for a little too long, it may take them around 10 days to germinate. Luckily, this won’t affect any characteristics of the future plant.
How To Germinate Old Cannabis Seeds
There are several tricks for germinating old cannabis seeds, all of them aimed at making the shell softer or thinner to help the sprout break out:
- Germinating cannabis seeds with hydrogen peroxide. Before germinating old cannabis seeds, try soaking them in a glass of room-temperature water with a teaspoon of hydrogen peroxide mixed in. This solution will help rehydrate and soften the seed’s shell. After 24 hours in this solution, switch to your preferred germination method.
- Scarifying old seeds. This is another proven method of germinating old cannabis seeds. Try lining a small matchbox with sandpaper, placing the seeds in, and shaking them there for about a minute. This will cover the seeds in microfractures, making it much easier for the sprout to break through. After scarifying the seeds, use your preferred germination method.
Tips For Caring After Germinating Seeds And Seedlings
As we’ve already pointed out, cannabis seedlings are very gentle, and you need to be careful not to put them in any danger or stress. Use the following tips, and your seedlings will make it safely to the next stage of their lifecycle.
In order to germinate and survive the first days of life, cannabis seeds and seedlings need to be kept under certain conditions like warm temperature, high levels of humidity, darkness for seeds/lots of light for seedlings, and, of course, peace and quiet. Outdoor environments can therefore be too unpredictable – if the weather changes and brings heavy rain or wind, or if a bird or cat decides to try and snack on the seedling, the young plant most likely won’t survive and you’ll have to start all over. That’s why we recommend germinating your seeds and growing seedlings indoors, where you have full control over their environment.
Choose Soil For Seedlings Wisely
There’s a common term among growers used to describe soil extremely rich in nutrients, and that’s “hot”. While hot soil is beneficial for cannabis in general, especially when made and used correctly, hot nutrient-rich soils, or super soils, are not the best option for young marijuana seedlings. In the early stages of cannabis development, the plant’s nutrient needs are quite low, and too much of them can actually hurt the young plant’s health. So, make sure to use more neutral soil for seedlings. A good trick that you can implement in your practice is to cover nutrient-rich soils with a layer of a more neutral medium and plant the seedling in this upper layer. The plant will develop, and once it’s ready for bigger nutrient intake, its roots will reach the underlying “hotter” soil. Remember that the vegetative stage requires nitrogen-rich media.
Give Seedlings Enough Light
After spending so much time inside its dark shell, seedlings are hungry for light, and plenty of it! As we suggest starting your plants indoors, this means you’ll need to install a light to satisfy the seedlings’ needs. The vegetative stage of cannabis requires mostly blue light spectrum, so anything from fluorescent lamps to full-spectrum LEDs, 100W and up, will work fine for seedlings. Just make sure the light is placed close enough to the plants. The optimal distance for fluorescent lights is 5-6 inches (13-16cm) and 8-12 inches (20-30cm) for LEDs. In case the seedlings need more light, they will let you know by getting tall and leggy. This condition is dangerous for them, so make sure your baby plants are receiving enough light.
Keep Them In A Mini-Greenhouse
Finally, another nice touch to keep your sprouts safe and sound would be to provide them with a small improvised greenhouse of their own. Loosely covering the starting pots or pellets with a plastic bag will do the trick. However, in garden stores, you can also find specialized containers with tall transparent lids. Whatever you choose, this will help the seedlings stay warm, hydrated, and safe from any dangers of the outside world.
Is It Legal To Germinate Cannabis Seeds?
This is a tricky question to answer, as the situation depends on the jurisdiction of your country of residence.
If you’re a citizen of Canada, the U.S., the Netherlands, or Spain – all countries with lighter cannabis policies – it’s legal to germinate cannabis seeds. However, additional rules apply depending on what part of the country you live in and what seed type you want to germinate. Nonetheless, it’s safe to assume that germination of cannabis seeds is legal everywhere where it’s legal to grow cannabis, and especially if you’re planning to start a garden of medicinal marijuana, you likely won’t break any rules by germinating seeds of strains with THC content lower than 1%.
In other countries, governments may draw the line at germination. For example, in the UK, it’s legal to trade and keep cannabis seeds, but you have to be careful with their germination, as this is where the law gets broken.
In our blog, we’ve covered the legality of cannabis seeds and everything you can do to stay safe. For more information, check out the following articles:
- “Where in the World Is It Legal To Buy Cannabis Seeds?” for tips for residents of Europe, China, South Africa, New Zealand, Turkey, and more.
- “The Legality Of Cannabis And Its Seeds In The UK”

- “Canada Pot Laws”
What’s the best temperature for germinating cannabis seeds?
Cannabis seeds prefer a warm environment for germination, with the most optimal temperature being 25C (78F). However, it’s okay to add/subtract a couple of degrees from this number while still keeping the air warm.
What’s the best pH for germinating cannabis seeds?
The perfect pH for cannabis seed germination is between 5.5-6.0.
What’s the best soil for germinating cannabis seeds?
It’s better to use light, easily drainable soil for germinating seeds, as this will not restrain the growing sprout. The soil for germination and seedlings should also be neutral or very light on nutrients – “hot” and nutrient-rich soils are only suitable for mature cannabis plants.
What’s the best humidity level for germinating cannabis seeds?
The germination stage requires high humidity levels of 80-90%.
What’s the fastest way to germinate cannabis seeds?
All methods described in this article are more or less the same in terms of the speed of germination. Much more depends on the freshness of your seeds – the fresher the seeds, the sooner they will germinate.
Do weed seeds need light to germinate?
Weed seeds germinate in the dark. So, even after you put a germinated seed in soil, you can keep the lights off. Until the seed pops up through the surface, that is.
Will cracked seeds germinate?
The protective shell on seeds is there for a reason, so any cracks or chips decrease the chances of successful germination. However, much depends on how long ago the crack appeared. And, anyway, it never hurts to try.
How long for cannabis seeds to break soil?
If you put a dry seed into wet soil, don’t expect the sprout to appear sooner than 60 hours. For pre-soaked beans or those that were put into the soil when they had shown a taproot, this may happen earlier. Sometimes in as little as 12 hours.
Cannabis seeds sold in reputable seed shops sprout very fast. Seeds that are old or have been stored improperly may take up to 10 days to sprout.
Starting Off Right
Now you can see that growing marijuana from seed isn’t at all that hard. Just remember to give your seeds enough TLC and dial in some environmental conditions to fit their needs. We’ve shown you some of the easiest and most effective methods of germinating pot seeds. Which one is your personal favorite? Let us and fellow growers know in the comments below.

I’m trying my first seeds using the glass of water method, some seeds have sunk to the bottom and some are floating, are the floating ones no good?
If you lightly “tap” the floaters after they’ve soaked overnight, they’ll sink, they just weren’t heavy enough to break the surface. If they float back up, let them soak another day and tap it. If it still floats, you may have an issue. However, I’ve experienced floaters and after the overnight soak, every floater I needed to tap, sank, and germinated fine.
I used a cotton pad, wet in clear container w/ saran wrap over put in sunlight and after first day checked every 12hrs, and they cracked on the 2nd day. worked well
Hello Keepinit, we are happy to hear that our article is useful to the growers, we wish you best of luck in your hobby!
what i find the most effective way is placing in a coffee filter then putting a coffee filter on top, then put on a plate and place a cup over the seeds and coffee filters and keep moist until germination occurs
What’s the longest you’ve ever had to wait for a seed to germinate and still had a normal, healthy plant? I’ve had 100% success the last 4 strains I’ve germ’ed with seedlings showing in 3-5 days. Recently got 10 Northern Lights seeds from a local vendor, and the first three went 15 days and nothing. I retried with two more and I’m on day 8 and still nothing. Maybe just a bad batch of seeds.. I’m behind schedule now for my next grow!
most good and healthy seeds sprout after a couple days, some older seeds take longer. I usually give them a couple of days to germinate if i still see no signs after 5-6 days i start to get worried.
15 days is a lot. I’ve waited a week at most, longer than that u will see the seed get darker, kinda sluggish nd swelled, that’s a dead seed decomposing, sometimes they just flood
How’s it going? I’m new to the game and was wondering the best way of altering PH level of water? I have an abundance of 500ml bottled water that has a PH of 7.9, a good way off the optimal PH 6 required I know, but is there a way of adding solution to each bottle separately and if so any suggestions of best solution to use? Thanks.
Yes there is ph tester for water that takes drops to test which is the most efficient way to test ph. Also to adjust the ph you want to get ph-up or ph- down I believe general hydroponics is the company for it.
The pic at the top is wrong ,the seed is up side down pistols or the hairs should come out of the seed butt hole that’s how the pollen gets in .2 hairs pair seed one for seed the other for the food sac ,
What happens to Seeds overtime they dry out and the carbohydrate that’s inside of them to feed them becomes weaker. As far as the potency of genetics that does not change however I recommend soaking all Seed between 12 and 24 hours. I use of seed starter MassiveGro invented formula pH to round 5.8 I pour about a quarter inch in a cup put my seeds in there put the next couple on top of it to force them down into the liquid. Occasionally give them a shake you don’t want them to be floating when you plant them. Then I soak my paper towel are use the nice cotton felt like paper towels I think a Brauny or veva with that seed starter formula pour the seed right onto it a ring out the excess moisture put it in a 1 gallon freezer bag place bag up high where it is 80° or put it on the heat mat with a thermostat and check it after one day because it’ll sprout fast. I like to let the sprout get a half inch long and then plant it The biggest problem you have with old seed is the lack of carbohydrate it may sprout then usually burn up all it has and die right away. Unless your seeds got hot you probably won’t have any problem unless they’re more than four years old. Old seed you can assist the carbohydrate by watering the soil with potato water a few drops of corn syrup or a fish fertilizer soak and Endo Mycorrhiza sprinkled around the seed. NPK industries wrong line of Omina is a good gentle amino acid helps break down substances so plants uptake faster when everything’s good I usually mix half strength of the weak dosage. NPK raw stuff can be bought on Amazon in small 2 ounce packages there everything’s pretty concentrated usually last you quite a while. But This is where a seed starter formula comes in because it usually has the carbohydrate to keep it going right away. I use pro mix BX with added perlite and when plants are tiny etc. I always measure my water and times with measuring spoons till a plant is healthy pro mix keeps plants from damning off as long as you’re not drenching it right away because it doesn’t dry out very fast easiest way to kill seeds to drowned it that’s why I measure watering and write it down I don’t try to push or stress my plants I either used seed starter fertilizer or plain pH water until they are about 6 inches high before a poor nutrients to them and once a week I do a full soil drench and drain prior to that you’re probably talking tablespoon or two of Water. Never let your pH get above 6.4 you lock out nutrients and you also root slower, once your plants are growing an strong between the 6 inch and 12 inch stage I’ll use about two weeks of red light will actually give you more roots.

How to Start Weed Seeds for Hydroponics
Now that it’s legal to grow your own weed in dozens of states, many people are moving to hydroponics for their seed growth.
There are various benefits to this form of seed germination, but the process has to be done correctly in order to get your cannabis seedlings to form healthily. If you put the time and effort in at the beginning, you’ll create a hydroponic system that does most of the work for you later.
Creating Cannabis Plants From a Hydroponic System
Sure, it’s easier to buy an already germinated seed rather than taking the time to do it yourself.
But the costs add up quickly, whereas germinating cannabis seeds hydroponically yourself gives you a solid return on your investment.
Rather than buying sprouted seeds and adding them to your water system, you can have a successful germination rate. This process also takes away all the disadvantages of the seeds you get in the store.
Why You Need Hydroponics in Your Life if You Grow Cannabis
If you don’t want your cannabis seeds limited to what other people sell, growing seeds is the way to go.
Plus, you can avoid the concern of picking up diseases from store-bought marijuana seeds and spreading them to your young plants.
Once you get the hang of how to germinate cannabis seeds and tend to your hydroponic system, you’ll never want to grow seeds through any other growing medium.
Turning Quality Seeds Into Cannabis Plants
Because the root system in hydroponics never connects to the soil, any seeds sprouted stay safely floating until you’re ready to use your marijuana plants.
So, any sprouts emerging from your system stay healthy and untraumatized.
How do you take a few seeds to germinate, design a hydroponic system, and start growing marijuana yourself?
Here’s all you need to know about germinating cannabis seeds for the maximum yield possible.
Starting Your Hydroponic System
Ready to see how good it feels to watch your cannabis seeds germinate into a young plant?
Sprouting seeds is a simple way to increase your healthy plant yield. You end up with multiple cannabis plants rather than one healthy seed bought from a store.
To ensure you germinate seeds that can successfully grow into a cannabis plant, you need a hydroponic system.
It doesn’t have to be fancy, but the costs at the start will be more expensive than buying a sprouted seed.
Remember, though, that getting a few seeds over time will end up costing more than investing in and creating your own method of germinating seeds at home.
What Every Cannabis Seed System Needs
In a cannabis plant’s life, there are four main components.
As long as you learn these factors and use them in an organized manner, you won’t have to add too much more equipment or do a lot of work after the initial setup.
Germinated seeds in hydroponics don’t need soil growers like your average growing plants do when you use potting soil.
Instead, they just require the essentials: oxygen, water, a light source, and heat. As you start seeds in the system, the proper lighting and the right temperature are crucial.
A Simple Beginning that Anyone Can Do
Let’s begin the process of designing your first greenhouse hydroponic system starting small.
You’ll need a grow tray, some starter cubes, and a humidity dome to monitor the temperature and moisture levels.
Starter cubes aren’t necessary, but they do make a massive difference. They have the ideal nutrient solution, like peat pellets, to help those first seeds sprout.
Once the young seedling reaches the stage where it’s able to be transferred, you can easily move the planted cubes without disrupting the roots.
This helps prevent root rot from excess water and gives you the maximum yield possible.
Adjusting the Temperature
Within the dome, your grow tray helps your plants grow from feminized seeds into healthy cannabis plants ready for the flowering stage.
For your role, you have to monitor the temperature and humidity. If you see water dripping from the side of the starter cube or dome, there’s too much moisture.
A heating mat under the grow tray helps avoid cold temperatures messing with the starter cubes and the seedlings.
Because even warm water turns cold, this heating mat keeps the grow tray at the ideal temperature to nestle the seeds inside and encourage them to grow.
Finding the Right Light Source
When it comes to adding lighting in the room, you don’t necessarily need more light. You need something that the germinating seeds grow toward.
In the case of cannabis plants, many experts recommend a hydroponic LED grow light system.
Cannabis is a green plant, so it must have the ideal environment to encourage photosynthesis. Seeds sprout naturally when the lighting initiates this process.
Then, the plants capture the light and use it to change the water and the given nutrient solution into oxygen and the compounds you desire.
These little seedlings need intense light, which is found in an LED grow lighting system.
Enough light at the right intensity will ensure you get the maximum yield possible from younger and older seeds.
Sprouting Your Seeds
Now that your environment is set up, it’s time to start the process of germination!
First, take your starter cubes and let them soak in clean tap water. In an hour or so, take two or three seeds and add them to the cube.
You should use enough to ensure at least one germinates, but not so many that if they all do, they’ll be overcrowded. As they begin to grow, any plants that look like they aren’t as healthy as the others can be thinned out.
Move the Starter Cubes
Next, take your grow tray and add an inch of half-strength nutrient solution.
Place the lighting source and mat where they fit best, then add the dome to keep the temperature and moisture at optimal levels.
Add your starter cubes into the tray, add a little water (not too much, you want to avoid root rot), and that’s it!
It will take a few days for seeds to germinate, but you’ll see whether your system is working or not by the fourth day.
Get Ready to Transport!
The seeds are germinating, and you can see roots daintily hanging out of the cube’s bottom. It’s the moment you’ve anticipated since you started your basic hydroponic system.
It’s time to transplant your young plant!
Chances are, it’s only been a month or less, but it can feel like forever as you’re checking and double-checking the plant’s health.
Now, it’s the real thing, and you’re moving your seedling into your actual hydroponic area.
This is the bigger tank or pond where you’re going to hold your nutrient solution and let your plants thrive until you’re ready to cultivate them.
Gently Move the Cube
Once you have a place for the cube, use the paper towel method to hold under the roots as you gently pull it from its grow tray.
There isn’t anything that connects the roots to a soil system, so a wet paper towel is all you need.
The roots are going to need a little time to get used to their new environment.
While they try to absorb the system’s nutrients, you can add a little water to the top or use those wet paper towels to cover the cube.
As the paper towel dries out, you know it’s time to add a little more moisture. Within a day or two, your new seedlings should be enjoying their hydro system without help, and you can drop the paper towels.
Enjoy Your Hard Work
You’ve taken your cannabis from small, non-germinated seeds to a young, healthy, green plant. From there, you guided it and monitored its growth as it flowered.
Now, it’s time to cultivate the good parts and turn the leftover cuttings into more cannabis seeds.
The return on your investment starts now. Rather than heading back to the store to find more cannabis seeds to germinate, you have everything you need to repeat the process.
Your grow tray is ready to house some more starter cubes. Your light source is still intensely shooting out waves of photosynthesis-inducing light, and your humidity dome is set at the ideal temperature and moisture.
Go ahead and take those new seedlings from the plant you nurtured and turn them into new young plants. You’ll never have to buy your cannabis stash again!
