The Wall Fan 40 cm Fans. 2 Units is a pack designed for Indoor cultivation that frees up floor space and maintains a constant breeze in rooms and grow tents.
Two wall fans with a diameter of 40 cm offer ample airflow, easy control, and stable installation for homogeneous microclimates.

The Wall Fan 40 cm. 2 Units Fans pack brings together two wall-mounted devices designed to move large volumes of air without invading aisles or work surfaces. The elevated mounting allows you to direct the airflow towards the canopy or intermediate areas, creating cross circulation that reduces heat pockets and moisture stagnation.
Each unit, with a diameter of 40 cm, covers large areas and facilitates an even distribution of airflow in medium-sized tents and larger rooms.
The manual control by cord or front panel (depending on the version) simplifies speed adjustment and activation of available functions, while the lateral oscillation—when present—distributes the airflow across the entire front of the grow area.
The wall-mounted structure prevents tripping, protects against irrigation splashes, and keeps wiring organized.
This pack fits both domestic and professional installations, where high foliage density increases transpiration and constant air renewal is required to stabilize temperature and humidity.
Combined use with extraction, injection, and carbon filtration enhances gas exchange, strengthens stems with a gentle breeze, and reduces the likelihood of mold in dense flowers.
All this makes this set a strategic choice among cannabis growing accessories and a practical solution for those seeking stable performance in cheap indoor grow tents without giving up professional ventilation.
In indoor growing environments, continuous circulation is needed to homogenize the microclimate. With Wall Fan 40 cm. 2 Units Fans it is possible to create cross currents that sweep the canopy from side to side, minimizing thermal stratification and promoting gas exchange throughout the volume of the tent or room.
It is used to prevent fungi and pests by breaking up stagnant areas, strengthen stems with a continuous breeze, and stabilize environmental parameters in scenarios with high foliage density. The two-unit format allows you to cover aisles and sides, or work in parallel to increase effective airflow over rows of pots.
Among indoor growing accessories, this pack provides versatility and order. Wall installation frees up floor space for pots, trays, and irrigation systems, while keeping work routes clear. Multi-step speed control makes it easy to adapt the airflow to each stage of the grow and to current climate conditions.
Installation recommended from the start of the cycle. For seedlings and cuttings, a gentle flow helps dry surfaces after watering and strengthens structures; during growth and flowering, the double fan maintains a uniform breeze between branches, reduces condensation on compact flowers, and helps dissipate heat emitted by lights, especially in hot periods.
Select a solid wall and mark the anchors. Mount each fan at a height that allows it to sweep the canopy without directly impacting flowers for prolonged periods. Aim the head towards aisles or sides to generate an enveloping flow and, if the version includes oscillation, activate it to distribute airflow across the entire width of the grow. Choose low speed for seedlings, medium for growth, and higher for flowering or when relative humidity rises. Keep grills and blades clean every 1–2 weeks; dust reduces airflow and increases noise. For automation, use compatible timers or environmental controllers, respecting the maximum loads indicated by the manufacturer.
