grow tent temps

Greeting growers . Ive been wondering this for a while.Would it be possible to make a grow tent have cooler temps then the room temperature.Lets says have 75F in grow tent and outside of grow tent(room) have 85F room temperature. Im basically asking if its possilbe to have a cooler temp in grow tent than in room. If so will this be possible in a 36in X20in X62in grow tent with a 400W MH 6 inch 530 cfm inline air cooled hood with speed controller. with two 4 in 175 cfm 1 for intake 1 extra for exhaust

dunno..try it and see.

i actually dont have the equipment right now. just ordered air cooled hood and 6 inch inline should be here in a week or so. anyone know?

You need something to generate the cooler air then, otherwise your box will be at best the ambient room temp or higher. You just need to find something/somewhere to get the cooler air from. if youve got a big freezer and a bit of time on your hands you could do what ive seen some people try and get a bunch of like 2 liter bottles or gallon milk jugs or etc and fill them with water and then freeze, get at least double as many as you think you'll need at a time, that way you can switch em out every 8 hrs or so.

yes its possible but like dark destruction said ur gonna need cooler air..im using a 48x24x60 and my temps r like 75-65 degress but im using a window ac with tubing hooked 2 the bottom vent 2 pump cold air in from the bottom up..i have an inline fan i never use (or not yet) but if ur using a 400 and the same inline fan as u stated i think ur temps can stay pretty low..like maybe 78-88..my tent is 71 dgrees right now and my room temp is about 80-83 ..

Ive just got my big room setup i have 3x 600w with cooltube i suck air in from outside and my flowering room is 72 degrees while my tent which has a 400w in is 80 degrees cool tubes are the way to go, its just where to get the cooler air maybe a cellar?
