Ventalation Question

Hi there, is it possible to grow with only fresh air coming into the growroom thru a vent and not have one for stagnate air to go out of? thanks.

if your using hid's higher than 250-400 then yes, but otherwise it should be good with a fan

and people usually vent out with a carbon filter for smell

ok, yeah i'm growing with floro's and the reason i asked is because i don't want to cut two holes in the wall seens how i'm renting lol, do you think it would stunt growth at all tho?

if you have a nice intake on the vent and a fan inside with floros you will be good

not like 50 floros though, then you will need one

yeah i'm using 8 48'' 32 watt floro's with 4 warmer and 4 cooler lights in a closet

i think you will be ok, if you your budding them with that light I suggest start flowering like 2 n half weeks into veg maybe 3

is your room totally light/air proof ? if not then you dont even need an intake but thell do better with one

Just go with an exhaust, it's easier to move the hot air out
