This ducting from Dimlux works with the heat extraction system on the Dimlux light fitting. It fits onto the outlet ports on the unit for passive heat extraction, meaning you could lower it a bit closer to the plants. Even a small drop can make a lot of difference in the light available to plants. Simply connect one end to the light and the other end to your current ventilation system. DimLux 50mm Combidec Ducting is also for use on the Nano tube fitting from DimLux. This system completely encloses the lamp in a a glass tube which extracts through a separate exhaust port.
