Hi all

I have a Grow Tent 1m x 1m x 1.8m and a 400w HPS is 85msp per hour (23Ltr/sec) or should i use 110 ms (31 litres per second)

Regards

your using mesurements for liquid, thats whyits a bit confusing, a 50 cfm (cubic feet per minute) would be fine..... they are bathroom exhaust fans for arounds 20 $ at the hardware store

Hi wel, I agree with MOBY... sort of.. LOL

IT may be enough.... it depends.... what temperature is the fresh are going to be?

You should have a fan also BLOWING AIR UP at the HPS bulb... blowing the hot air, up and away from your plants

You would be really happy if you got a NICE strong INLIONE fan and directly exhausted your HPS.. dealing with heat issues, is a real bitch... it is worth the investment to FIX it once and for all..
