The smaller the cabinet, the more difficult it becomes to vent heat out.
Rusty Trichome Reviewed by Rusty Trichome on . What's the right size cabinet for a 600w hps? I'm going to make a basic square cabinet. - 600w HPS hanging from the top. - temperature activated fan to cool - Black & White poly on all the surfaces. - 6" square pots (each 1 gallon) with soil - standard grow nutrient, but no co2. How big should the cabinet be? Rating: 5
