Currently i have 3 plants. 2 of them are seedlings and ive been keeping them outdoors, my other one is flowing in my grow room. The summer hasn't even started and already it gets riduculously hot in there witch is why i took out my two seedlings because i don't think they were diggin it lol. I currently don't have a fan or any ventelation system. My grow room is a closet about 10' wide 3-4' deep and about 7' tall. I want to set up another grow soon but im kind of sceptical because of the heat that is going to be coming. The summers here get up to 105-110 degrees. Im wondering if i used a 400 watt hps what kind of fans/ventalation would i need and about how much it would cost me, because if its going to be really expensive i'd rather set something up outdoors. Any help is appreciated thanx
