Air movement is very important in your grow area as it can prevent stale stagnant air.
A small amount of movement on the plants will help to strengthen the plant’s stem, which in turn will allow the plant to hold larger flowers and fruits. The constant air movement also means that there will be less heat build up in the room.
Oscillating fans can also be used to direct cool air at specific areas of your garden – particularly useful if you have suffered from any mould problems, mildew or botrytis (bud rot).
