Using air cooled hood to regulate temperature?

Hey,

I 1 1000w hps and 1 400w hps on air cooled mavrick sun 6" and the 400 watt is in the 6" sun tube. The question is can I quit running air through them til my room heats up to like 72 degrees and then have a thermostat turn them on? Or will the bulb get to hot if thats possible?? any input helps!

absolutely. That is what I do. The trick is to figure out when to turn the fans on as rooms tend to get slowly warmer and warmer as the day goes on.

A simple thermostat switch will turn them on but you would really get the same effect by just putting them on a timer.

One word of advice, get rid of that cool tube "reflector" those things have the worst performance of any horizontal reflector..EVER. nevermind if your using it vertically

Thanks! Glad to hear that you do the same thing! Yeah I'm not impressed with the sun tube I just got it for really cheap with a bulb.
