The double flange kit connects to the intake and exhaust blowers of a HydroHut. Simply place the double-collared flange through the vent opening then sit the faceplate (O-ring with holes) on the opposite side of the tent fabric and connect together for an air-tight fit. This dual flange kit fits all HydroHut duct vent openings, but be sure to confirm the size your indoor greenhouse uses. The dual flange allows you to vent either the lighting system or the HydroHut tent (or both).
