you can actually go with a 1000 on 4x5 but with the height i would prob go with a 600.
i would paint the inside a flat white paint for reflectivity.

good luck on your second grow
texas grass Reviewed by texas grass on . First cab recirculating dwc grow First of all hello to everyone; I'm finally ready to start my 2nd grow.:D For this time around I'm trying to go a little more stealth than just in an open closet because I live in an apartment. I have a pretty good sized cabinet; the first pic is the cab without any modifications. I replaced the back (that was just a piece of cardboard) with a piece of plywood, and removed the separator in the middle for 2x4 studs. (So I can have one open space) Iā??m going to try a recirculating DWC system Rating: 5
