The bulb you were interested in would work just fine. 7200K should produce some great results.

I would probably go with 60/40 OF/Perlite, I've seen OF compact pretty badly. And with that, you could likely do almost the entire veg phase and only need to add nutes come flowering time.

Never heard of the paint you're talking about, though I would wager since it would work on a roof, it would work on other rough surfaces, you just need to worry about even application.
khyberkitsune Reviewed by khyberkitsune on . Indoor Grow Box Set-up Here is a quick layout on my ideal grow box. Im going to build a custom cabinet type grow box. As you can see in the photo its 3'x3'x7' and I plan to use a 4" exhaust inline duct fan with a carbon scrubber, im not sure what size intake vent hole yet, 400w HPS lighting, 2 CFL side lights, and a circulating fan for strengthing stems and in case I need to cool down the temp a bit. Any ideas on what I should add or change? Any suggestions on how many plants I can fit easily? Rating: 5
