You would be better positioning lights over and around plant than taped to wall.
You do need about 4x 10mm holes in the bottom or you could drown the root mass, the root mass needs to start drying out 30 minutes after watering the plants( the roots need air)I topped the plant and the pots pretty heavy should I drill some holes for drainage or is it straight
Yes if it helps to keep your temps in range.Is it ok to run lights 24 hrs
keep the light on 24 and see if it starts to flower, then you will know.I think it’s not femeniles and it’s not auto flower
I managed to fill a 2x4 with a single plant at 11w/ft². Ended up with 4.5oz. I've plenty of mates with 40w/ft² that yielded less so I'd say a big part of it is environment, genetics and care as well.25w ft2 is the lowest you want to go with a cheap led.
