you would be ok with no filter. Thats kinda pushin it tho.

I will be growing lettuce in it if you didn't read 2 posts up. Not rasta lettuce, like romane lettuce as I am going to postpone growing cannabis until I move to a medical marijuana state and get a card, or until I am living on my own. So no filter, but 1 odor eliminating bulb will be in there just incase.

that's just a very small space; how much light do you need? how much heat do you want to deal with? i don't think i'd want to deal with an HID in that space

70w HPS and maybe a deodorizing light bulb would be no problem in a cooltube. 150w is pushing it... I don't know if the 70w will provide enough lumens though. 1.8 square feet and I will be using it all with plants. So around 6000 lumens from the HPS, then 1600 from the deodorizing light bulb, so that would be 4222 lumens per foot, that is acceptable.
