I have a small tent practicing on these two bagseed plants. These are 3 weeks old just using MG all purpose, its 8% N. This is an experiment with the PV cells to stimulate growth, so far its made them stretch since they are about 2" away from 2 all blue 14w led panels. I would think one panel per plant would be good to veg and they wouldn't stretch. Can you see how purple the stems are?
