Question on my 400 HPS Setup

Hey guys.

Im about to start some aurora indica tea, and wanted to pass this grow setup by the experts. Ive got a 400 hps, with a single reflector overhead. My idea is to get 4 pieces of OSB board, paint them bright white (or use mylar, havent decided yet) and use the boards as a big box to set my girls in the bottom of it. I assume I would need some serious ventilation, but I figured I could leave a hole for 2 fans on either side of the setup for a sort of cross-breeze.

Make sense? This is my 1st.


Thank gang!

if you're going to use a cab, ventilation is needed. if it's a big room that's climate controlled, you wouldn't have a problem. i use a 400w and a 1k in a room with no exhaust; the lights keep the room around 70f.

if in a cab, i would recommend a cool tube device. cabs get hot with hps very very quickly...

what is a cab?
