If I have big enough fan and filter can I flower in open basement? Or do i have to flower in tent or built sealed rooms for smell of flower.
Well it like this NO. I have my tent set up in my old den (basement). Although I shut the door down to the basement (I do all my maintenance on the freezer (comfortable height)) within minutes of taking the plant out of the tent, it smells in the mid level hall (4 level side split). I can isolate the back Hall/front foyer with a French door but I still have to operate a deodorizer in the front foyer, in case someone comes to the house even if we are legal here. I will add we have forced hot air heating here and of course there is a cold air return in the basement, this occurs whether the furnace is running or not (read during the summer). My tent vents outdoors and the exhaust fan still pulls the smells from the tent/den out. It doesn't matter, that stuff goes everywhere.
You again?
It's not so much if I give a fuck or not... it's all about remaining stealth.
