An oscillating fan circulates the air inside the grow tent or grow room: it evens out the temperature, prevents pockets of humid air between the leaves and strengthens the stems. It does not replace the extractor fan, which takes the air outside. Here you will find Ralight 45 cm, 130 W fans in pedestal, wall-mounted and floor versions.
A circulation fan does not take air outside: for that you need inline fans with a carbon filter.
At 45 cm in diameter, the Ralight fans are designed for grow rooms and large tents, as a guide from 120x120 upwards.
| Ralight 45 cm version | Where to use it | Recommended position |
|---|---|---|
| Pedestal | Grow rooms and large tents with floor space | Adjustable height, just above the canopy |
| Wall-mounted | Grow rooms, fixed to the wall | High up, aimed over the canopy |
| Floor | Grow rooms and large tents | Low down, to move air under the canopy |
Leave the fan running with the lights off too: without the lamp the temperature drops by 2–6 °C and relative humidity rises, just when the risk of mould increases. If humidity stays above the values for the stage (45–55% in flowering, 40–50% in the last 2–3 weeks), circulation alone is not enough: you need more extraction or a dehumidifier.

Yes: without circulation, pockets of warm, humid air form between the leaves. An oscillating fan breaks them up and evens out the climate.
So that they move air above and below the canopy without blasting the plants directly: the leaves should only just move.
Yes. With the lights off, relative humidity rises and still air encourages mould.
