marijuana seed when to give light

I hope you continue to enjoy the blog.

For those who are growing indoors, cannabis seedlings may be put under lights as soon as they emerge from the soil or growing medium.

My sprouts are about 2 1/2 – 3 inches tall. They have produced the first and second smooth leaves, as well as the first serrated leaves. They also have the second, tiny serrated leaves coming out. But the initial leaves have turned slightly yellow. I’m concerned that I am, perhaps, overwatering? Any suggestions will be welcomed. (Thanks for the suggestion for moving air. I will try that to strengthen the stems because they will go outside once the threat of frost has passed.)

Comments

If they lean or tip over, I use the soil around them to “mound” around the stem. Makes them wicked thick in maturity.

Good afternoon Jon,

Thank you so much for sharing your experience.

With best wishes,

Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.

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.

Training plants

However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
