how many lumins would i need for a 4X2X5 grow tent? i was ganna use about 18,000 or so
i think he means AC hood = Air Cooled hoodYep, I agree with Legal, I have a 400 in a 4x2 space also.
You can get by without the A/C though. Air cool the light and run lights at night.
I agree, 400watt HPS.... these are fairly cheap and very effective for small grows.You want 50-70 watts per sq.ft. So in your case, a 400 watt would be best. Your going to need to need a decent fan and AC hood to keep temps down.
