Zimbogro

In Africa (secret location, stealth grow). RDWC(CCH2O/ Spectrum King Led). New grower (Nov 2017), imported all my kits from USA (the best guys in the business). I have a 4x8 and 10x10x11 Gorilla tents in a 20x15 room. Intake HEPA filter in adjacent room next to window (always open). Exhaust air from 10x10 goes back into grow room in a 8" duct with a 4" duct also taking air out into adjacent room to avoid positive pressure build up. A 10" fan and Phresh filter is on LOW to filter and redistribute air in room.
