Wasn't so much btu as it was using darker shade cloth or section off areas keepng consistent temps. Depends on greenhouse size.

It will be a 20 x 40. I want to vent in summer and cool it with ac in winter with dehumidifiers and add co2 burner.

probably only a 5 ton but not really needed. I run larger size gh w/ lights and co2 and the fans will only come on sometimes on a sunny/hot winter day.
