If I were to have say a regular fan and a open window 90% of the time would this be able to get rid of the smell of Cannabis being grown or should I abandon hope until I can afford a carbon filter. Because I have a box that is I would say 3 foot by 3 foot maybe and would of growing about 5 plants and toping it to keep it from growing out of hand. My possible weed will be either blueberry or bagseed. Is it possible to cut off the part at the top to keep it from growing anymore?because my idea would involve one light among the plants with aluminum foil lineing which I would use to reflect lighting and keep it 24 hour lighting until they are a foot tall then force flower them with either a 12 12 or 18 hours of darkness and 6 hours of lights. Does this sound like a good idea so far I am a little unsure since its a cardboard box. lol might not be a good idea. Thanks for any help.
