If possible, get feminized seeds. Because female pot plants produce the bodacious bud that cannabis connoisseurs crave, starting with feminized seeds will produce more buds when the plants mature. Feminized seeds won’t provide 100% female plants, but they will greatly increase your odds from the 50-50 chances of a standard seed selection.
How long does it take to germinate marijuana seeds? Typically, it will take anywhere from a couple of days to up to a week to see your seeds start to turn into plants.
Germination simply means getting a seed to sprout a taproot, which will serve as its main root into the soil as it grows. For the best results, start with the best seeds you can afford to buy online or get from friends.
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.
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Is the seed viable?
Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Pros and cons of using cannabis clones
If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
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.
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.

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.
