Duct Fittings


Temperature and humidity are very important for healthy plant growth and can be controlled with a capable fan and fan controller. The heat from the lights is used to maintain an ideal temperature while a fan controller controls humidity and replaces stale air with fresh air and CO2. C02 controllers and TNB Enhancer bottles can provide extra CO2 if neccesary and a quality carbon filter will remove any unwanted odours. 


We sell a range of SMS fan controllers and in-line fans for any situation, as well as co2 controllers and carbon filters from Cann and Rhino. We have been selling these filters for years and feel they are the best in their class. We also have a wide range of ducting and duct fittings, humidifiers and Ona air fresheners.
