I have a 90cm x 90 1.2m high indoor grow . I had four ten litre tubs under a 400w light in coco and air post .. All vented ect, setup is pro setup ... I had to lollipop my plants because it was such a small place the bottom was receiving little if no light.... So I was thinking is there away round this but not topping ! Or am I better to put 2 plants in a nft setup = plants get more light and more bud or 4 plants and risk the over crowding... Any advice or info greatful only my second grow so a newbie really
