I can't get them under more light ie the sun for another two weeks i'm going to try to leave them in those pots as long as possible they have a long grow period ahead as they are going till fall. I have a heat pad to keep them warm can the lights be further away when there true leaves get bigger? And interesting opinion on paper towel it kind of makes sense
What happens when you have smallish containers with young seedlings is they are growing roots exponentially now. You don't want to root bound them early on.
That will trigger the plant to stop growing vertically or at least slow down vertical growth and start side branching.
If you want to go outdoors or into a greenhouse you will have lots more VERTICAL space than horizontal. You want them to grow tall. Get them into bigger pots so they continue to grow taller. Once you change location in a few more weeks they will take off if you give them enough soil.
You can VEG a cannabis plant for a very very long time. I have some mothers that are 2 years or more old right now. Soon I will just cut all the tops off and make them clones and toss the mother. The clones will be the same age as the mother. Round and around it goes. New set of donor plants for clones that go into flower.
The Mother should be a worthy selection. Just a little food for thought going forward, should you find a plant you really really like, or a friend really likes. Won't have to purchase seeds. Well thats the idea anyway.
You mentioned greenhouse I think?? Just be careful with Tomatoes in with cannabis. They attract pests (tomato) that are harmful to cannabis.
Spinosad is a friend for IPM.
IPM = Integrated Pest Management.
IPM is very simple start reading up on it when you get time.
It's obvious you know how to grow plants. Use the same technique you do for your veggies and flowers with the cannabis.
Someone here gave me that advice a long long time ago.
I grow my cannabis much like we grow our Hydrangea outside. My wife kicks my ass routinely with bigger badder hydrangea flowers and they last longer too. sadly. lol
