Our exclusive Air injection rings by Jet-Stream cover a wide area of our 20ltr or 36ltr RDWC pots and feature pinhole-sized pores to create the tiniest bubbles possible. The smaller the bubbles the more surface area of oxygen is touching the nutrient solution and therefore the more that fluid is becoming oxygenated. This should result in highly aerated and healthy root zones in your plants.
It is advised that your air rings be held to the bottom of your Silver Pro series 20l or 36l pots with at least 3 large suckers per air injection ring (Sold separately).
