I've read the ventilation 101 thread from a while back and am having some trouble. I have a 5x5 tent with an ac infinity t8. I am debating converting an old shop into a 4-6 flowering light grow. the space is around 20x15x10 feet. I have been running the numbers on ho0w much it would cost and was trying to find out what type of exhaust fan I should use. Would it be viable to just use a larger inline fan or to use something different? I was planning on install 2 window ac units into the space probably around 8k-12k btus each. I live somewhere with hotter dryer summers so proper air conditioning would be necessary. I'd appreciate any help. thanks
