How to choose ventilation ducting for a grow tent or grow room

How do you choose the right ventilation ducting for your indoor grow room or grow box? We have prepared an overview of three basic types of ventilation ducting and practical tips for their use.

Choosing the right ventilation ducting is essential for the efficient operation of the ventilation system in your indoor grow room or grow box. Ventilation ensures air circulation, removal of excess moisture, temperature regulation and odour removal, all of which are key factors for the healthy growth of your plants. In this article, we will introduce three basic types of ventilation ducting, their advantages and disadvantages, and provide practical tips for their correct use.

ALU aluminium ducting (ALUFLEX)

Flexible ALU ducting is made from a combination of aluminium and laminate. The ducting structure consists of steel wire wound between several layers of material, which gives it the necessary flexibility. ALU ducting is easy to shape, which allows simple attachment even in hard-to-reach places or where obstacles need to be avoided. The ducting material withstands temperatures from -30 °C to 140 °C and a maximum pressure of 2,500 Pa at an air speed of up to 20 m/s. ALU ducting is particularly 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 aluminium, while the outer layer consists of a durable protective plastic. COMBI ducting is durable and flexible at the same time, so it can be used for complicated and heavily loaded connections. The COMBIFLEX material can handle temperatures from -30 °C to 140 °C and a maximum pressure of 3,000 Pa at an air speed of up to 30 m/s. COMBI ducting is suitable for air distribution as well as connections between fans and odour filters.

 

Acoustic SONO ducting (SONOFLEX)

Flexible SONO ducting minimises noise caused by flowing air. The ducting consists of a hardened aluminium inner section wrapped in an insulating layer of mineral wool. SONO ducting significantly reduces the noise level of the ventilation system and is particularly suitable for air distribution. Like the other types of ducting, SONOFLEX withstands temperatures from -30 °C to 140 °C and a maximum pressure of 2,000 Pa.

Tips for installing ventilation ducting

When installing ventilation ducting, bear in mind that every obstacle the air hits reduces the efficiency of the fans and increases noise. The fewer bends and the shorter the duct runs, the quieter and smoother the operation of the ventilation system will be. Use metal cable ties to attach the ducting to fans, odour filters and connectors, and check the joints from time to time to make sure they are sufficiently sealed. Between individual growing cycles, dismantle the ventilation system, clean it and, if necessary, replace worn parts.
