hey all, my first harvest is curing as we speak. i ended up with 22 grams of smoke from one plant. i'd like to make a few improvements to my growbox and i'm hopeing for some tips and constructive criticism.my box is made of plywood. i just painted it flat white.it measures 2'x3'x6' high.my first grow had 336 watts of cfl. i had one 85cfm cpu sucking hot air from the box.passive intake from the bottom of the box. my temps ran from 77* to 86*.i'd like to up grade to a 400 watt hps but i'm concerned about the heat. i'm thinking of a hydrofarm light with an air-cooled hood. would an additional 85 cfm fan and 4" ducting be enough to cool the bulb? i could also add another cpu fan in the top of the box to pull out hot air for a total of 3 cpu fans. i have a 6" ocillateing fan mixing things up inside the box. i hope to grow 3-4 plants. would i be better off going with a 250 watt hps and some additional cfl's? my last grow was in dirt but i'm thinking of trying a DWC hydro set-up.any thoughts?thanks in advance.
