Beacause I have a window in the cellar I have had to seal every lil gap with sealant in order to make it light tight for when I switch to flower and I have no fresh air gettin to the room as of yet but I'm gonna put ducting straight from the airvent and lead it to the bottom of the grow roo
The sooner the better, because lets face it you cant live without air so dont expect your plants to:hippy:
