Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
Time to germinate
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.
If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.

So now you know how long cannabis seeds germinate, what will happen after?
Your probably not gonna get all 20 seeds growing. The seeds you wanna use are the thick, "beefy" ones. usually brown in color with "tiger stripes" on them. also most regular brown seeds pop too. But defiantly not the lil green ones. Those are immature seeds
Ph’ed water all over a paper towel placed in a baggie. throw the seed up in the thing and close the damp paper towel over the seed. DON’t close the bag. Place the bagggie on top of a warm place like a cable box or p.c. Place a bowl over the bag to trap heat. Over night the seed will POP. The tap root soon follows. 100% germ rate for me.
yes the soil will be to hard. You best bet to assure outdoor growth: dig a big enough hole to fit a large pot. Dispose of the dirt u dug up and fill the hole with a top soil mix or organic mix from your local nursery or hardware store. Make sure the area you plant the seeds in is an area that has loose soil that becomes spongey when wet, holds water well, and drains well.
yea your being a little impatient. When u germinate seeds in a paper towel it usually take 1-4 days for the seed to crack, and another 1-2 days before u see any decent taproots, then u plant them and another1-3 days they will pop from the soil. You just don’t see the work going on beneathe the surface. Keep it watered. Give it about a week. If ya don’t see anything in a week, week in a half, then ya have something to be worried about.
Until then. your gonna need time and patience, expecially if your working outdoors. You got til September-October buddy.
12-24 hours to crack if the seeds are fresh but can take up to 2 – 3 weeks for older seeds.
if they are in soil then it deppends how deep they are?? give them 7 days im sure they will break through the soil in that time.
Watch that GT and FDD. hahaha
