? about using a/c efficiently

[jimjay]

In a grow with exhaust/intake how can a grower use a/c efficiently?
With air being exchanged so fast it seems like the a/c would always be trying to "catch up" especially if the intake air is warm. Is it better to cool a lung room and have your intake pulling that air vs having a a/c unit in the grow?
Im trying to plan out a new setup and really want to get my environment dialed in and a sealed room seems like the best way to do it.

Lung room ftw.

Sealed room mean's no intake/exhaust when light on ,some exchange air at night.

I know what a sealed room is. Im asking how efficient a a/c unit is when air is replaced so fast in a "open" room. I would think a a/c is better for a sealed room where the air isnt being replaced.

It will cool all surronding space(house) if big enouft so not efficient i.m.h.o.May i ask what is the purpose of using a/c if not sealed?

If you're using an a/c exhaust fans should be off. You should have 3500 btus for every 1kw of lighting. If your trying to cool 8 thouusands with a 12,000 btu portable give up now.

There's no efficient way of doing it. You're having to replace the air thats being sucked out every 5-10 mins. A lung room won't help because you want the a/c thermostat in the room where the heat is so you can regulate temp in that room. I personally recommend 5000 btu's for ev 1000 watt light. You'll find on super hot 90+ high humidity days, 3500 btu per light will not be able to keep up. Plus the extra 1500 btu helps account for the added air exchange. What will help is having the cool air from the room used to cool your lights and exhaust that warm air outside of your grow space. You can also look into portable swamp coolers. These use water to cool your room and will help your a/c cool the room better
