hi pple thanks for viewing and answering. ok so this is my first time doing dwc and i a m currently using a 20 g. rubbermaid tote bucket. i have 6 plants and they seem to be really crowding. i am current ly under a 4 ft by 10 inch t5 sunblaze and i am planning on flowering under a 600 watt hps. so plants seem to be really crowding but they are not growing to the spread or what the 600 watt covers .now are there any suggesstions on how to make sure that i get a full canopy for the 600. ?
