Going to be starting a freezer grow soon,and had a few questions about what fans to use... First:Wanting to know what size fan to keep a 600 watt HPS in a cool tube ummmm cool.The light will be getting fresh air and exhaust out of either side,not from or into the freezer itself. Second:What size fan,working through a carbon filter(2 feet in lenght x 6" diameter tapered to a 4" duct),should I use to help control temps/fresh air(working with a thermostat) Set up will include: Freezer is 31.1 cubic feet 2x5gal DWC 600/400 watt NextGen MH/HPS with Cool tube(400w for any blooming needs/600w for flowering) FANS ? Modeled somewhat after Rumple's grow,so all the extra fixings to the grow space are not listed above,but if any of it pertains to my question,I will answer accordingly Any help will be appreciated Also,does Rumple have a link to his grow room build....
A dayton blower would be the fan I would use. Hit up rumple or don piano either one of those guys will help. I have some of rumples info on how he built his room. Ill forward the info if you want. Also you may want to ask this question in growbox/design section.
