i forgot alot of what you said amount of plants and such. you only have enough lights for one -two plants. here is an idea that will help maximize your yield. make a scrog screen homemade take take either one or two metal hangers depending on the dimension of your box. bend them around the perimeter and secure it to it then weave fishing line or thread or dental floss into squares like a checkerboard . weave your plants through the scrog screen this will keep all your buds sites at the same level move your lighting down to the new canopy height, and you must resist picking buds to test. just wait tell it is done. do this you will be thanking us later show me some pics if you do the scrog screen , and i will help you further.
