How to Choose Ventilation Ducting for a Growbox or Grow Room
How to choose the right ventilation ducting for your indoor growroom or growbox? We prepared an overview of the three basic types of ventilation ducts and practical tips for their use.
Choosing the right ventilation ducting is crucial for the effective operation of your indoor growroom or growbox ventilation system. Ventilation ensures air circulation, removal of excess humidity, temperature regulation and odor control—key factors for the healthy growth of your plants. In this article we introduce three basic types of ventilation ducts, their advantages and disadvantages, and provide practical tips for their correct use.
ALU ducting made of aluminum (ALUFLEX)
Flexible ALU ducting is made from a combination of aluminum and laminate. The duct’s structure consists of a steel wire helix sandwiched between several material layers, giving it the necessary flexibility. ALU ducting is easily shapeable, allowing for simple mounting even in hard-to-reach places or where obstacles must be avoided. The material withstands temperatures from -30 °C to 140 °C and a maximum pressure of 2500 Pa at air speeds up to 20 m/s. ALU ducting is especially suitable for connecting fans and carbon filters.
Rubber-coated COMBI ducting (COMBIFLEX)
Flexible COMBI ducting is designed to be resistant to mechanical damage. The inner part is made of aluminum, while the outer layer consists of a durable protective plastic. COMBI ducting is strong yet flexible, so it can be used for complicated and heavily stressed connections. COMBIFLEX material handles temperatures from -30 °C to 140 °C and a maximum pressure of 3000 Pa at air speeds up to 30 m/s. COMBI ducting is suitable for air distribution as well as connections between fans and odor filters.
Sound-dampening SONO ducting (SONOFLEX)
Flexible SONO ducting minimizes noise caused by moving air. The duct consists of a rigid aluminum inner part wrapped in an insulating layer of mineral wool. SONO ducting significantly reduces the noise of the ventilation system and is particularly suitable for air distribution. Like the other duct types, SONOFLEX withstands temperatures from -30 °C to 140 °C and a maximum pressure of 2000 Pa.
Tips for installing ventilation ducting
When installing ventilation ducting, remember that every obstacle the air hits reduces fan efficiency and increases noise. The fewer bends and the shorter the runs, the quieter and smoother the ventilation system will operate. To attach ducting to fans, carbon/odor filters and couplers use metal hose clamps and occasionally check joints to ensure they are properly sealed. Between growing cycles, disassemble the ventilation system, clean it and replace worn parts if necessary.
