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.
Make sure the area the seeds are in is warm, somewhere between 70-85°F.

Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
Are you ready to grow?
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
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.
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.
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.
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.
