Please help me out here. I am growing in a box the 2'wx2'dx3't. I have two plants inside currently that I am experimenting with under 6 CFL all 23 watt (actual). I know that this is not enough light but as it is, I am having issues with heat. I have one 4" intake down low , one 4" exhaust on the back wall mid way up and one 4" exhaust on side wall up top. I also have two more passive vents on the box as well. My temps inside the box spiked up today to 86 degrees! The temp in the room is 77. How can I get my temps inside the box down to where they should be? I originally had one of the exhaust fans as an intake but a member here advised me to have more exhaust than intake so I turned one into exhaust. It does not seem to be helping. Please advise! Thanks!
