You should put the exhaust fan on a thermostat.. Two 400 watters are gonna get very hot. Are your hoods enclosed? The 435 should be used with exhaust and the smaller fan really ain't needed. The exhaust will create a passive flow into the tent while the exhaust is on..
GaGrown Reviewed by GaGrown on . Ventilation question Hello folks, I am starting a 48X24X60 grow tent and I just had a few questions about ventilation. 1. My plan is to use a ValuLine 6 in Centrifugal Fan - 435 Cfm for fresh air intake at the bottom of my tent and then an Active Air Blower System - 60 CFM at the top of my tent for exaust. Would this work? It sounds like it could be too much intake and not enough exhaust? 2. My second question is about fan timers. Is it ok to just run these fans non-stop or do I need to invest in timers? If so Rating: 5
