Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
Within a week or so you should see a seedling begin to grow from the soil.
Pros and cons of using cannabis clones
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.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
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.
About half the old seeds sprouted, and the rest were duds. I planted the sprouted seeds and watched the seedlings carefully to see if they would grow. I didn’t expect much from them, but they did grow into healthy transplants that were eventually planted into the garden.
Step 6: Check seeds daily. Examine your seeds each day for germination and to make sure the towel stays damp. Spray the towel if needed.
Benefits of Pre-Sprouting Seeds
Step 3: Dampen your paper towels. Spray the paper towels with your spray bottle. You are aiming for the paper towels to be damp, not dripping. If you notice the water pooled in your container, dump out the extra.
A seed is triggered to sprout by warmth and moisture. Normally, you sow a seed into a growing medium, such as damp seed starting mix or peat pots. Then you cover the seed with soil, water, place in a warm spot, and wait for the seed to sprout and break through the soil surface.
I had pepper seeds that were several years old. I hated to throw the package away without checking to see if they were still good. I checked the viability of the seeds by doing a seed germination test.
Seeds need three things to germinate:
After germination takes place, the best temperature for growing seedlings is about 10 degrees cooler than the temperature in which they germinated.
Always plant seeds at a depth of 1-2 seed sizes. So, the bigger the seed, the deeper you need to plant them.
Do Seeds Need Sunlight to Germinate?
Seeds are in a state of dormancy, or suspended animation, until exposed to these three elements.
Some species of plants, such as begonias and coleus, need light to germinate, but if you’re germinating vegetable seeds, don’t worry about providing lights.
Now, keep the containers out of direct sunlight because any trapped heat might fry – literally – the seeds.
After 24 hours of soaking, plant them immediately into soil, whether that’s in a pot or in the ground. This method works with all seeds, but I find it works best with larger seeds, such as bean or squash seeds.
