my a/c is a dehumidifier as well thanks.You can get a good portable AC for 300-350 but it will have to be vented outside. That will definitely keep it cool. Those also work as humidifiers not dehumidifiers so you may also need a dehumidifier. Even upper 80s is too hot.
Why haven't you run air in take and outlets yet? Carbon canister? Very easy to run your roof for fresh in/out dependin winter /summer and the other in to the rrom below so you can switch with seasons. Why no co2? you can just DIY it if your strapped for cash. I too have an attic with similiar height restraints.
i didnt run air intake because i am about to move into a new house so i dont have to be strapped for space and height not to mention i have 2 box fans and 4 oscillating fans in also in the flower room. co2 will come i ordered a 3 burner co2 generator for my next spot.how do the buds look you think the 27000 wat cfl will do anything in the last couple weeks?
