My grow room is 3.5x5x8(an old bathroom).using an aero set up(14 sites 5 inch net pots 25 gallon res with a chiller along with 16 plants/1 gallon bags with soil)with a 400watt mh/hps ballast and bulp with no reflector.I dont currently have a co2 tank and regulator but do have homemade co2.I have 2 bathroom ehxhaust fans in the ceiling about 200cfm combined I think.I have a intake fan that was given to me but dont what cfm it is.It looks like an older model. I want to upsize all of my fans.Its almost summer and will be growing indoors all summer long.I have central air but still worry about heat build up.I dont really no much about intake/outtake fans,cfm,air filtration and the noise it will emitt.I live in a 2nd floor condo.Any imput would be helpful.
thanx
