dumb ass, check your local weather forecast and see how much the temp changes from day to night and from day to day. you're worried about 5 fucking degrees?
god you're so completely full of shit. what does the book of the dead (which you haven't read) say about quantum physics and how do you know is says what you claim it does?
that's an impressively long-winded way of avoiding admitting that you've never read anything written by ancient egyptians. do you even know how to read hieroglyphs?
fuck you, fuck your imaginary god and fuck your illiterate, child raping, slave trading, mass murdering, genocidal, scripture plagiarizing, dog hating fraud of a prophet.
there's no point having your exhaust fan up high when you've got an ac and humidifier blowing air around. you want it as close to the top of your light as possible to suck up the heat it puts out before it can be blown around the tent.
a thick slab of styrofoam under your tent will keep your roots from losing heat and having your air inlet at the top of the tent and outlet at the bottom will pull the waste heat from your lights down through your plants.
you're wasting a ton of light and generating more heat than needed. put up some white plastic sheets or silver foam board or something. and try to concentrate the air conditioner more on the plants.
