Hi, If those messurements are metric then you have a 600W HPS light & ballast inside a 31"sq tent 62"tall? and you want to keep it cool without expensive equipment? I think you're dreaming, that light puts out far too much heat to be contained in that small enclosed environment. That's where LED ,T5 florescent or other low heat lights are needed, then intake and exhaust fans will work. Otherwise you're fighting a losing battle with heat and humidity.IMHO.
It’s in cm
I have now bought a inline extractor fan should do the trick
I will post some picks of my grow area later today or tommorow
I run led inside
I think that's the trick of it all, when you're talking about an enclosed environment. I use a 1000 watt hps in an open air 5x5 square room curtained off to prevent light leakage from my curtained off 5x4 sq veg room where I use t-5's and t-8's. Most of the year I vent the heat from the flower room into my veg room because there's not enough heat keeping my plants warm with the low heat florescent lights in my basement. We only have a month or two here where the heat I get from the HPS is a problem. I'd like to switch to LED's to save on electrical costs but I'd have to heat my rooms so there'd be no savings.
