i would vent in "cold air" vs exhausting your grow rooms air. doing that (exhausting your issues/heat )not only gives away your grow rooms smell. you will have to use more power by a huge % to cool it vs bringing in cooler air and having the inline fan on a temp controller
plus if you do co2, more sealed and less exhaust = the better and less cost on ya. co2 exp once the room is properly stabilized you can easily run a hotter room and the co2 and higher nutes will bring 20-35% more vigorous results and yields.
Sealed is the only way i would do and some co2, if not thats a huge degradation of your final and plants results, it would be like suffocation with air for a human and wondering why they cant complete their workouts or live as good.
with co2 and higher ppffd =
900-1500 ppm co2, in flower i try to do 1000-1350ppm and on last two weeks before harvets i gradully lower co2 each day and hit till 900-1000ppm to not only save cash but also uneeded .
feed based on co2, so if co2 900 ppm, feed @ 900ppm
tip for feeding:
seedling-3rd week start with 1/4th strength base (epsom @ 1/4 cup per 50 gal whole veg cycle) and anything else your giving at start-mid veg stage, than gradually raise ppm 300-500 mid range veg to 5th week, 5th week-8th week/end of veg gradually raise 500-750ppm
flower feed: first week of bloom ( even in veg stage a week before flipping them to flower stage) = add some bloom booster at 50% for a week before bloom-end fo week 1 bloom. For epsom rate for 1st week-5th week apply at 1/2 cup per 50 gallons than week 2-5 gradually raise your bloom base and misc based on ppfd and co2 and once u hit 5th week apply 3/4 of a cup per 50 gallons epsom salt + PK bloom booster at 25-50%
like co2 and everything your plant intakes, its all about gradually giving more and not over doing any of the inputs or its not only wasteful but stress.
temps 78-86f on canopy
water 68-75f, it can be warmer but biggest issue alot of people they dont uv clean their water if it isnt city water. then they dont sterilize their rez everytime. those things are asking for bad pathogens go wild in organics. if you sterilize and have a preventive scheme for such those issues will be at bay but also you can have waayy longershelf life on your rez/feed before going "bad"
