Many of us have had this nightmare-come-true in our indoor gardens: You walk into your garden one evening only to find it extremely hot and full of wilted plants. Astounded, you look around to find the cause but you hear it first. The duct connecting the fan to the exhaust has broken and you are not evacuating the hot air, just moving it around.

Well, put your mind at ease with ThermoFlo 2000SR ducting. 2000SR is the strongest ducting on the market.

Available in even sizes from 4 to 14 inches.
