Hello all. I have a cabinet right now that 30"X18"X60". I also have a 400w Lumatek MH/HPS with a sealed air coolable hood W/ 4" flanges. I have been thinking about putting the light in the cabinet w/ 2 180cfm fans. One to cool the light, and one for ventilating the cabinet itsself. The cabinet will be flat white on the inside, and smell is a problem I have a carbon filter. Would this set up work? Or is the 400w just way too much for this area? I was thinking that maybe with 180cfm aircooling the light, and 180cfm of ventillation I could keep the cabinet at a reasonable temperature, but I am not sure. I am afraid the there will be too much heat. And can you have too many lumens? I believe I read the rule of thumb was 50w/sqft, or 5,000 lumens/sqft. That would mean this would sit at 106.6w/sqft, or 14,666.6 lumens/sqft. Is this too much? Will the light just go to waste in this area? I was thinking about an autoflowering strain, because of the dependency on light. Any and all help is appreciated!
