Germinating weed seeds in plastic bag

Germinating seeds>sealed bag and tissue and plate

I am experimenting germinating I have two seeds AK48 and Afghan Silver. I have put the AK48 in damp tissue and a sealed bag while I have put the Afghan Silver seed in damp tissue on a plate I have placed them both in a warm area to see which takes off first.
I will keep you all updated and let you know which seed roots first and I will post pictures once they start Thankyou

I usually just soak some paper towels with a 1/4 tsp or so of SuperThrive. Fold it up put in a zip lock bag fold it up. And put it under a flap of the mylar about some cfl I use in a clone box. 24hrs nice roots easily. The SuperThrive old timers advise to help producing females. Could just be a wise tale.

“wives tale” as in “old wives tale”

Not to be a dick or anything, I just would rather someone corrected me if I misspoke than let me keep saying something incorrectly.

Anyway, I have always used a damp paper towel in a plastic bag, not sealed, so as to allow some air circulation. Nowadays, I am more inclined to just drop it in some moist soil out of direct light. Or a starter plug. Actually, I will probably end up using the paper towel thing again. Always reverting to what I know works.

OK, I’ll bite and make the correction as I have for many years. Using any (non-conventional) method other than sowing directly in soil is, well, quite ignorant of plant processes.

Sheesh. only in cannabis forums. If it’s popular it’s usually wrong.

Light is OK, and direct sun all day is best once the seedling starts pushing.

Here’s my archive:

Germinating Cannabis Seeds (for Bio Growers)

Your seedlings will be alot better off if you germinate directly in soil – less handling and mechanical disturbance means less chance of physical damage to the plant’s taproot (and roothairs) and less food reserves used to position itself due to the natural hormonal influence called Gravitropism. That translates into less food reserves used and increased seedling vigor, especially in the very early critical stages of seedling development.

This is my foolproof method for Cannabis Seed Germination in soil:

First, if harvesting seeds from my own crosses, I air-dry newly harvested seeds for a couple of weeks, and then store them in the refrigerator with a little rice. Cold-treatment seems to increase viability and germination rates, especially with indica-dom strains. I almost always get a 100% germination rate with quality seedstock.

Soak the seeds in plain water for 12 hours prior to planting to hydrate them, which will speed up germination. In general, good seeds will sink, bad seeds will remain floating (they contain air, not an embryo). I first sterilize seeds in a bleach solution (1 Tbsp. bleach/1 gallon of water) for 1/2 hour to kill any fungus residing on the seedcoat.

Sterilize enough *damp* fine soil with heat to germinate all of your seeds. You can do this by treating the damp soil to temps of (no more than) 200F for 20 mins in a conventional oven, or in a microwave oven on high for 2 minutes, while stirring a couple of times. Your goal is to get and hold the entire soil mix’s temperature at 170F to 180F for about 20 minutes which can be monitored with a probe type thermometer. Let the mix cool thoroughly. This will insure that damp-off fungus spores have been killed in the soil mix. Make sure the soil mix is light and humusy (not real coarse). You can add a little sand or vermiculite to aid in drainage and weight.

Buy some white 20oz styrofoam “drinking glasses”, commonly called “Styro-Cups”, and punch holes in the bottom (and side bottom) for drainage. I use a red-hot ice pick for this. These containers are 6 1/2″ tall and will allow ample room for the taproot to grow before cotyledon emergence which will increase your seedling’s vigor. The taproot (radicle) is already at least 4″ long at the point of emergence – don’t restrict it (in order to maximize seedling growth rate). Styro-Cups can be found on the shelf displaying picnic items at your local grocery store.

Fill the pots almost to the top with your soil mix, water well to settle the mix, take a pencil and make a small hole about 1/4″ to 1/2″ deep, NO deeper, and drop *one* seed in. Cover the seed with *fine* soil, only enough to top up the hole, firm lightly with your finger, and lightly water until water runs freely thru the drain holes. Place in a warm spot around 80F/26C. Do NOT cover the cup with saran wrap or anything else. The seed has been hydrated from the soaking and will germinate soon. This container should not require further watering until the seedling is up and running.

During the first couple of days, mist the top soil surface lightly (if need be), never allowing the top to crust over, but not to the point that the medium stays waterlogged which will invite pythium rot (damp-off). “Less is more” at this point. Do NOT water this pot any more until the seedling is up, and only if it needs it at the point of emergence. Again, no need to cover with plastic wrap as the radicle (taproot) will grow at least 4″ before the cotyledons emerge from the soil. IOW, even though you can’t see it, the plant’s root is seeking and finding moisture at the container’s lower soil levels. I cannot emphasize this enough. The seedling will emerge anywhere from 2 to 10 days from the time you sowed it.

That’s all to it! With good care, your faves will be ready to transplant within 1 to 2 weeks, and will easily slip out of the “cup” with a solid rootball that will never know it’s been disturbed if potted up gently and quickly. Move up to a final pot of 3 to 5 gallons to sex and finish.

How to germinate cannabis seeds

So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.

What is germination?

Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.

When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.

It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.

Preparing to germinate cannabis seeds

Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.

The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.

How to germinate cannabis seeds

The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.

How to germinate seeds in soil

Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.

First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.

Place the soil in a small pot and use your finger or a pencil to push a small hole in the dirt, a bit more than half an inch deep. Insert the seed into the hole and bury it with soil. From this point on, don’t touch your seed. The young plant is fragile and knows how to position itself in the soil bed.

Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.

Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.

When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.

How to germinate seeds in water

You can also germinate your seeds by placing them in water. It’s slightly faster than the soil method, but you need to adjust your environmental factors accordingly. Remember, successfully germinating seeds requires a perfect balance of ideal growing conditions. When germinating in water, seeds need only 24-48 hours to pop their stems, though cultivators can keep them soaking for up to a week as needed. Water germination is faster because the seed gets all the moisture it needs immediately, and the shell softens and cracks more easily after soaking.

To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.

The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.

The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.

How to germinate seeds using paper towels

The paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.

To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.

Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.

The paper towel method also has its risk, as the fragile seedlings can be damaged during the potting process. The tiny roots can also get tangled in the paper towels, so make sure to move the seeds to potting soil before roots grow too long. Use your hands or tweezers to gently remove each seed from the paper towels and place them in a prepared growing medium.

How do you germinate seeds indoors?

Whether you’re planning an indoor cultivation or outdoor grow, it’s best to germinate your seeds indoors. It’s easier to maintain proper temperature, light exposure, and moisture inside, and you can protect your seeds from the elements. Indoor germination, whether using soil or paper towels, will ensure your cannabis seeds have the best chance for survival.

To germinate seeds indoors, use any of the methods described above. Within a few days, you’ll have popped seeds ready to transfer to a growing medium.

Do you need to germinate seeds before planting?

While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.

Once your seeds have sprouted roots, they should be planted in soil, a soil-less medium, or in your hydroponic setup. Make sure not touch the root, caring for and navigating the seedling so that the roots face downward. Plant the seed about one inch deep in your growing medium, cover lightly, and allow for about a week for the seed to emerge from the soil. If the seed hasn’t poked through by day ten, it likely didn’t survive.
