starting weed seeds indoors under lights

Soak the pellets in warm water and then poke a small hole into them, about a half-inch deep and just big enough for the seed to fit snugly into. Here, they can be watered, kept warm, and even begin to take root. The whole pellet will eventually be transferred to wherever the germinated plant will be grown.

If it has not, the seeds should be moved to a different environment as too much water can drown them. 24-36 hours is the maximum recommended time for this and is only needed on seeds that have dried out for a long period.

The following methods are all tried and true alternatives to the direct planting of the seeds. However, growers should take note of the color of their seeds before attempting any germination, as immature seeds will not be successful.

The concept here is to use a piece of growing medium, such as widely available peat pellets, and to plant the seeds directly into it.

Simply take the seeds and place them between a couple of wet paper towels. Next, take the towels and put them between two plates to create a sort of protective, dark dome. Finally, make sure it all stays relatively warm (70F-90°F) and after several days the seeds will begin to sprout.

Setups involving many pellets on a warming rack are colloquially known as “germination stations” and are very commonly used in both amateur and professional grows. Very little trauma to the seed can occur here, and the trauma of transplantation becomes a non-issue.

If you don’t want to mess around with assembling your own, or you’re not sure how or where to hang it, then I recommend getting a full system like this one. That’s a great option, and it makes setting everything up a snap!

Yes, if the seedlings are getting tall and thin, then they definitely need more light. I recommend keeping the grow lights on for 14-16 hours per day. The section above titled “How To Use Grow Lights For Seedlings” will help answer more of your questions.

Best Light Schedule For Seedlings

Otherwise, if you just need a refresher, or you want a quick-start guide, then my Starting Seeds Indoors eBook is just what you need.

Rotate the trays daily if you notice any of the seedlings around the edges are reaching, or aren’t growing as well as the ones that are directly under the light.
