Too much airflow?

hey currently running 2 400s in a 3 x 3 x 6 tent got a 6" inline cooling in batwings no cooltube.

so my question is can there be too much suction in the tent where the hotair wont properly vent out?

with the tent closed it has neg pressure but the temps on the top of the canopy are 100 but open its mid 80s
bottom of canopy's 70 closed 75 open

anyone know anything on this?

well you do need air in to get air out ... too much suction means you dont have enough air entering


happy growin

open up the vent flaps on the bottom of the tent. then vent out the top. cooltubes would help you out a great deal with your heat issues if you can afford them.

I must agree with both previous posters, make sure your vents are open for air intake, and cooltubes are great for keeping temps down. Only other thing I could think of would be to use a insane-o vent fan. In my closet i use a 449cfm Vortex vent fan for my 2 400W CMH bulbs (In a dual cool tube), with an regular AC vent intake. Well, you could maybe try using 2 400W CMH bulbs instead of the HPS or MH, the CMH bulbs run about 10 degrees cooler than the HPS (and are better imho!)

Setting up a grow is expensive and time consuming, but if you put in all the time money and effort ahead of time, it makes the entire grow easier!
