Hey guys, ive been a long time lurker here. I have a small cabinet grow, 30x18 x 55" tall. I have one plant in there under a galaxyhydro 300 and 3 small screw in led bulbs. Im wanting to build a cob light, but i cant decide on size, watts or how many chips i need. The Cree CXA 2530 seems to be a good chip but im unsure if its too big, or how many to get. I was thinking 3 inline, or 4 at 4 corners layout. I will likely do a water cooled system as where my grow is it will be easier to run water lines to a reservoir in the basement which is always cold. So for one plant in that space w a water cooled cob setup, how much do i need. Ive looked at alot of other diy cobs but they are all in bigger multi plant setups. I dont wanna build a light and burn plants.
