Air Circulation – Why It’s So Important!

When growing plants indoors, it’s incredibly important to focus on improving the air circulation. It may be unbelievable, but not having adequate air circulation will have devastating effects on your plants!

Having inadequate air movement in your grow room can cause negative effects on the health and strength of your plants. When in nature, plants have the air constantly pushing and pulling on their leaves. Therefore, when growing indoors – this needs to be mimicked. The easiest way to do this is by using circulation fans. These fans will push on the leaves and help them to grow thicker and stronger. Likewise, it also helps them to build up a stronger resistance to stress. Plus, your plants will develop thicker stalks to hold heavier fruits and flowers.

You’ll also find that it’s easier to develop diseases and infestations when not using Air Circulation Fans in your indoor grow room. Diseases such as fungal or bacterial infections can be easily controlled with a little air flow. Fungal spores will not be able to settle on your plant’s leaves, or even develop into a full infection! Plus, a strong air current will make it impossible for any pests to settle on your plants or lay eggs.

Air circulation is important for any sized grow room, small or large. There are plenty of different options available to suit almost every size grow room. In smaller grow rooms, fans will help to steady the airflow and keep a consistent flow of air. Whereas in larger grow room setups, you’ll want to add Air Circulation Fans to make sure air is freely flowing across all sections of the grow room. Therefore helping to reduce the build-up of stale air within your grow room.


There are plenty of different options available on the market, all ideal for different types of rooms and plants:
