How to determine size of Co2 Gen/Air Conditioner?

[Thehulkster321]

This is my first large scale grow ... I have 6 closet grows under my belt but thats about it.

I'm trying to determine what size Ac Unit and Co2 Generator I need for my new grow room.

The room is 12 x 10 and has 4 600w HPS and ts a basement grow so it stays relatvily cool.

The Co2 Generator, AC Unit, Ballasts and Outlets are all in a separate room from the plants to reduce heat.

Any one have a formula to figure out how many btu my AC needs or how big my Generator should be

1 ton for every 500 sqft

Here you go. It's how I picked mine. Scroll down a little to input your room dimensions and desired PPM (about 1500). Your question will be answered by the best in the field.

For CO2, not AC.

so it stays relatvily cool.

Then why bother with AC?

For AC I use 3000 BTU's for each 1k of light.
