What type of A/C are you running? What are the outside Temps compared to the inside temps. Are the wall insulated? Sorry for so many questions. I am having on built in 10 days just for growing. Just trying to get an idea of what I need without spending on the wrong stuff. I ordered 6x400w inductions lights and already have 5x300w LED lights. Also have co2 regulator,tank and controller. What size inline fan would you recommend? Thanks for any help.
