I was wanting to make the flowhood in the tek described and when i asked around on shroomery.org i was told i would need a blower three times the one i have for a 12x24 hepa after all the resistances. Is this true, has anyone had sucess useing a 265cfm dayton with a 12x24 fungi perfect hepa and a standard prefilter??
Thanks for your time
