But if the seed you found looks decent, you might as well germinate it and see what sprouts.
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.”
Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
Is the seed viable?
Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Pros and cons of using cannabis seeds
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
A clear plastic cover on the top keeps the warmth in. You can make one of these at home or purchase one inexpensively at your local nursery or online.
If you choose the seed route, you will want to know the best way to germinate marijuana seeds. Experimenting with marijuana germination is your best bet for determining what’s right for you, since even seasoned growers often argue about the best methods for germinating marijuana seeds.
When you are ready to plant, just add water. They will expand into little individual soil pots you can use as a growing medium.
The paper towel method is a favorite for many home growers. Simply take two pieces of paper towel. Moisten them with water. Then place your pot seeds in between the two layers of moist paper towels.
Some folks like to germinate their seeds in Jiffy Pots. You can buy these at nurseries and other places as little round disks.
Plant a seed or two in each pot, making sure to keep the pots moist. Once the plants sprout, you can transplant them in their Jiffy Pot to a container or to a raised bed or garden plot.
Lots of folks like this simple, direct method. Simply soak your seeds overnight in a glass of lukewarm water. The next day, plant them directly in the ground, containers or wherever you plan to grow them.
Select the Right Seeds
Put a plate or other object under the bottom towel to prevent moisture damage and another over the top towel to keep the seeds in a dark space. When you see the white taproot emerge from your seeds, they will be ready to transplant. Make sure to plant them taproot down.
Choose between indica and sativa according to your preferences for cannabis effects or the market’s demand. You will also have dozens of strains to choose from.
