Re: Port light exhaust back into room on a thermostat?

I want to figure out a way to port some of my light exhaust into my grow room if < than 65°F. Do they have a device such as this? Like a Y with a flap on an actuator that is controlled by a thermostat.

Or maybe just open a little valve like a fireplace thermostat on a valve. I am no electrician, or engineer. Not sure if it is ok to port exhaust back in.

See like this with some clever thinking.

This would work I wish I knew how to make it. No idea huh?

Put your exhaust fan on a thermostat, that way when it gets to a certain temp the exhaust fan will turn off allowing the room to heat up again
Once it reaches a certain temp that you choose the fan turns back on
Here is a good one: http://www.horticulturesource.com/c-a-p-custom-automated-products-cooling-thermostat-temperature-controller-50-115-f-with-3-temperature-probe-p5719/?osCsid=42bd847c76b4040ae505f249ebbaa50c

I am worried about the bulb not being sufficiently cooled for a lot of the night.. Worry wort?

That is a nice thermo cheapest good one I have seen so far, thanks.

You will be fine man that is how most ops are setup
The bulb life won't be effected that much by the fan turning off sometimes

Coolness, err uh warmness..

Thanks Bro
