right well deep breath. im planning on buying a darkroom 120 grow tent. which is 1.2x1.2x2.0 meters. its a thermal insulated so heat might be a problem with the 600 watt light that ill be using. so i was wandering what the ideal power of exhaust/extraction fan i would need, and what carbon filter to acompany it. ive been looking on various websites and online shops, and curious as to whether its possible to have a fan that is too powerful for the grow tent. i got too many questions at the moment lol. any help would be brilliant.
