enclosed hood will be the game changer there. butt if temperature is at 80-82 degrees, and you wanna fight fire with fire.. so to speak, run Co2. i keep my room at 82-84 with Co2 and the yield/quality is effing ridiculous. i understand if Co2 isnt in your budget at the moment, but a system including a tank and reg and suspended lines @canopy lvl, cost me close to 350.. best investment i ever made. tank refill is 17 dollars. im in cali, dont know the avail of co2 there.. sorry to hear of your illness, and i hope your health returns with the vigor im sure your plants will display.
ciao, damp
