What temperature does growrooms have to at night when the light is off?

What degress or fahrenheight does the enviroment have to be at nightime also should i leave my fans on or off?

I keep a steady 77 F all day long...seems to be working for me. Maybe the experts can fill me in on this if it really makes a difference to have lower temps during the dark period? I also keep the fans on throughout the day.

Generally you don't want a drop more then about 10 degrees F during your day/night cycle. Depending on where the stain is from I like to keep my temps around 75-80 with the lights on and about 70-75 with lights out... If you drop them too low you could stress them out.

It's a good idea to leave some fans on for circulation. I never turn off my fans...

And yes, i would keep the fan on 24hrs.

75 with lights on and 75 with lights off.

Without knowing how big your grow room is, we have no way to help you with ventilation questions...

I personally like these http://www.amazon.com/LEDwholesalers-GYO2402-6-Inch-Hydroponic-Booster/dp/B003YFADW8/ref=sr_1_2?ie=UTF8&qid=1350605075&sr=8-2&keywords=inline+fan

They work great and are cheap... You can have a couple on hand incase you need more ventilation or if
one burns out... They are a little on the loud side but they work very well IMO

Two of those fans I linked to will keep your tent very close to the room tempature +/- 5 degrees F. Only open 1 passive intake in the bottom for better results... my veg box is about the same size and I have a 400w in it with pretty much no problems... If you do have too much heat in there then add a 3rd exhaust... Winter I only need 2 summer I add the 3rd so I dont need to run my a/c all day lol...
