Need to move about 1100cfm total. Will be pulling like this:
Intake (multiple passives, 2x outtake size as min)->room->CAN filter->fan->hoods->exhaust
Using two tables w/ 3x600w each.
My bro who is setting this up is not real savvy with DIY/construction related stuff, so I've been drafted to help design and build the room....fair enough, he has helped me out in more ways than I can count in the past.
So, there is already one 6" vortex 449cfm in his meager collection of gear. My numbers show the need to move about 1100-1200cfm (there is some padding on those numbers for a safety factor). I believe he can do this with either one 12" Vortex XL or similar CanMax, OR can use 3 separate 6" Vortex.
Per the people at CAN, a can filter of the proper size for the fan + 25' ducting gives about .75 sp (or 0.5 with just the filter and no ducting). Per the Vortex people (Atmosphere) a 6" Vortex will move 300cfm at 0.75 and 350 at 0.5, while a 12" Vortex XL will move 1700cfm at 0.5.
Clearly the 12" moves more total air, but both should be sufficient on cfm.
COST: Add 2 more 6" for a total of say $325, or a single 12" XL for $650.
POWER: All would run 120v, and there is only one 120 circuit in this space (lights will be on 240) so total amp draw is an issue. 100w ea on the 6's for 300w total vs. 528w for the 12XL.
NOISE: 6" go at 49dB each, total at 54dB for 3 of them (adding sound levels is not simple addition, dBs are on a log scale) vs. 12XL at 67dB.
Cost, noise, smaller fittings, flexibility if moving to another grow space, no replying on a single piece of equipment, being able to build DIY carbon filters for half the retail price, and not having to build a plenum all point toward using the 3x6".
WHAT AM I MISSING? Or tell me why it would be better to go with the 12". He will not be expanding this particular grow, so the "buy more than you need" is already accomplished in either option.
what say ye?
