gettin blown

is an exhaust neccesary if temp is not an issue? fresh air coming in + climate control. seems exhausting the cooled air would be a waste. any thoughts?? thnks

As long as your bringing in fresh air (or adding CO2) you really don't have to exhaust the air. If you could seal of the lights and exhaust them without evacing the room air would be even better. You'll be able to run the lights a lot closer anyway.

Exhausting forces air into the environment from which it was exhausted, so you have air flow both ways already. As long as you get as much fresh air on the plants as possible, or close up the room and use Co2 instead and that's it!

bump...fresh air..
