how important really is ventalation.... and wuts the consequences for poor ventilation.... currently i'm setting up a 600watter in a 7x4 ft. room with 8 ft. ceiling. it is going to be in a nice cool basement so there shouldnt be any heat problems with also a few fans... because of uv nosy neighbors to the right and greedy neighbors to the left im going to be unable to open windows downstairs...also i have another problem... my girl will NOT let me do any modifications for circulating air from the outside in / inside out etc.. therefore will the sugar and yeast trick i read about on this forum work??....also the room is seperated from the whole rest of the basement so would circulating air in/out of the room to the rest of the basement help....any suggestions from experience would greatly b appreciated.... thanxx my fello growers
