400-1200w MH/HPS (currently running 1200w, dual 600w HPS)
Hydrofarm Radiant AC 8
8" inline duct booster fan 500cfm (exhaust)
8" window fan 500cfm
i have my hood connected to about 2-3ft of ducting that attaches to my 8" exhaust fan, which connects to about 4ft of ducting, which is connected to the 8" window fan (set to exhaust, which helps assist the duct fan from bogging down).
temps can reach to mid 90's depending on time of day.
so heres my idea on "boosting" my CFM's, or just to make a better exhaust fan, money is super tight ATM, so..........
I have lots of 120mm/4" CPU/axial fans, rated between 118cfm to 80cfm, & a few other sizes of CPU fans as well.
my idea was to take 3-4 of my 120mm (12v, .9amp, 118cfm), & somehow group them together to make 1 bigger fan, & then take this fan & either put it on the inside to push (boost) air through the booster/duct fan, or pull air through the other end (like the window fan) to help boost the booster/duct fans cfm/rpms.
these 118cfm fans are very very strong, considering they are .9amp each, just need somebody to so me how i can get them to fit into a 8" configuration to hook up to the 8" duct fan to boosts its cfm/rpms.
i plan to use 1-2 of my collection of cpu fans to build a carbon filter.
fyi, i have about 7-8 120mm fans, 2 80mm fans, 2 60mm fans, & various others laying around, all new, so if that helps.
so i just need help in designing a way to put them together in a group, or in a housing to hook up to the booster fan
