Here is some math for you to figure out!
CFM=LengthXwidthXheight. do that for your grow space that should tell you how much CFM you grow space has. You would run your fan 15min per hour would prob give u good results. Also as far as ur light requirements do LXW for grow space. You need 6000Lumens average per sq foot so 6K time your grow space will tell you how many lumens u will need. Look up Rosemans CFL tutorial and it teaches u about light requirements and much more
Ta. Am assuming 65 lumens per watt, giving me 375 x 65 = 24375
Using 80 x 80 Secret Jardin so seem to be on target
