Germinating cannabis seeds with paper towel is easy and fast. Use this step by step guide so that you don't make any silly mistakes. 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…

Germinating Cannabis Seeds with Paper Towel

One of the best ways to germinate your precious new cannabis seeds is to use the paper towel method. Use this step by step tutorial for germinating cannabis seeds with paper towel as a reference when sprouting your seeds.

Step 1 (Optional)

Soak your seeds in water for 12 to 24 hours and store in a dark location. It is very important that your seeds do not sit in the water for more than 24 hours because you run the risk of drowning them. Set a timer and don’t forget! I generally skip this step and go right to the wet paper towel.

Step 2 (Germinating Cannabis Seeds with Paper Towel)

Whether or not you soak your seeds in water (see step 1), will have no impact on how you will approach this step. The key to being successful begins with your set up. For this step, you will need a plate, a paper towel, a zip lock bag and some clean water.

Begin by wetting your paper towel on your plate. The paper towel should be completely wet, but not drenched. Drain the excess water.

You are now ready to place your seeds. Fold the wet paper towel in a way so that your seeds are sandwiched between.

Finally its time for the zip lock bag. Place your plate inside the zip lock bag and seal it. The zip lock bag will seal in the moisture and eliminate the risk of your paper towel drying out.

Step 3

Place your seeds in a dark spot and don’t touch them for at least 2 days. Room temperature will play a big role in how fast they germinate. Ultimately, you want your room temperature around 70 to 75 degrees. This will create a environment where your seeds should flourish. Check on your seeds after 2 to 3 days and see how they are doing. As soon as they sprout, you should plant them right into your favorite organic soil.

Hopefully this quick rundown gives you a better understanding for germinating cannabis seeds. Its pretty easy and straightforward. You shouldn’t have any trouble, the biggest mistake is forgetting about them! Just be sure to check on them regularly. If you need seeds, there are plenty of reputable seeds retailers around. Seeds can be bought all over the world and some of the best seed growers are located in Europe and Canada.

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.

The AK48 rooted first which i put in wet towel and put in a sealed bag had a look at it this morning and it had rooted so i have put it straight in to a sponge until it starts, I will keep you updated about the Afghan Kush I have put that in a sealed bag because I have seen how quick it roots Thank you

“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.
