You guys are funny lol. But back to the source I'm growing in a 6ft cupboard using 1 cfl light yes that is tin foil. I'm going to town soon to get more lights and a reflector sheet. My plant was stunned because I was using the wrong pH water but I caught it in time cured it and now you see the result from the pic I took last night . its grown dramatically . nearly got its full sett of 6th leafs. Iv been feeding it nuts ( tomato grow )thathat's the reason why its shot up within a week.. So I no its working leafs are a solid green out of lights. I was doing 18/6 cycle but I changed to 24/0 cycle to help it grow and its worked . so when should I switch it to 18/6 again.. I will upload a pic of it later with the new light n back ground ect
