you are gonna need more than computer fans to cool a 250hps in that space. i had over 200cfm total exhaust fans to cool a 150hps in a similar size space. i also had a couple 4inch duct fans for intake(1 above the screen and 1 below) computer fans are great for circulation in a small cab grow but the plants will be much happier with more powerful ventillation fans imo.
justaseed Reviewed by justaseed on . small grow cabinet suggestions The attachments below are pictures of an armoire that I want to convert to a grow cabinet. I'm thinking that becuz of the size limitation that a 250w HPS Scrog would be good. The dimensions are 3' 9" high x 3' wide x 1' 8" deep. I'm not looking 4 high yield, just some high quality buds. Would a 250w HPS be too hot for this space? Any suggestions will be appreciated!!! Rating: 5
