:rastasmoke: ok........keep in mind....hydro system...in a closet about
5'x2'(deep)x7'

have a dr60 grow tent (2'x2'x4'7''), the tent has passive air intakes at bottom for cool, clean air...getting a cooltube (19") (due to height constraints)...have a vortex (4" 172 cfm) fan that exausts to attic...planning on flowering here...have 4" filter that i want to chain in this order: filter>duct>cooltube>duct>exaust

I am pretty much set on getting a cmh (ceramic metal halide) lamp for the grow just because of the ridiculous spectrum...it's quailty not quantity here.

I want to go with the 400w cmh....(approx 34,000 inital lumen, 29,000 lumen mean).

I plan on flowering only 1 plant in here.

My questions are:

1. Can i use this 400w lamp in this situation? or is the lamp just over kill for 1 plant?

2. If yes, do i need to upgrade my fan?

3. If none of the above, any suggestions that would make this work???


Thanks in advance. :hippy:
