Air Pumps & Airstones

If you have a hydroponic reservoir in your grow system, you can do a lot of good by using an air pump and air stone in the bottom of the tank to keep the solution well mixed and fully oxygenated. Plant roots love oxygen, and so do the beneficial microbes that grow in the root-zone. By using an air pump and air stone you will help to ensure you maximise root growth and health. In DWC bubbler systems they are absolutely essential, so it's a very good idea to keep a spare pump about!
