I have a large and well equipped grow room for my second grow, before I grow on a large scale I want to be sure I have everything ready. Do I need to have an air intake and exhaust if my room has a 24500BTU air conditioner with built in dehumidifier and a 11000BTU CO2 burner to produce more CO2? I will be using 5-8 liquid coolder 1000w HPS lights and five 4x4 ebb and flow trays. Thank you all in advance

If anyone with experience could answer this I would really appreciate it.

damn, thats a nice setup.... don't know the asnwer to your question, but I would put them in if i were in that situation.

Thanks for the compliment my setup has cost me a pretty penny, I was hoping to avoid punching holes into my walls if possible, also I was concerned that the exhaust would vent out the CO2 produced by the burner, if someone could give me their expert opinion i would be grateful

the exhaust will absolutely pull out the co2, so don't have the co2 running at the same time as your exhaust, but I think you will have no choice but to have an exhaust and intake, temp control is key.

I have 8 liquid lumens liquid cooled 1000w HPS lights that will run around 70-80F I also have a 24500BTU Airconditioning unit which is used for the grow room alone, so heat should not be a major issue. With the AC and a CO2 burner do I still need an external intake and exhaust?

how big is the grow room?

Only run your co2 at lights out and your exhaust is off.

Ok so I'm sorry I am a total noob. I have the best equipment but that deffinatly doesnt help when you have a total lack of knowledge like I do.. I have been running my CO2 when lights are on, and keeping it off when lights are off, dont the plants use CO2 most with lights on or do they use it most at lights off or equally? Also having an exhaust is necessary even with the window AC unit and the CO2 burner?

The room is about 140 sq ft
