Good Drainage Equals Healthy Roots
Foam Pot Raiser is designed to lift your pots off the ground to ensure adequate drainage. This is critical in all hydroponic systems except deep water culture (DWC) to minimise root rot and other problems caused by wet feet.
For re-circulating systems, pots MUST be higher than the brain/return reservoir. Similarly, in a run-to-waste system, pots must be higher than the waste catchment. If they are not, the roots will be constantly sitting in nutrient solution.
Use pot raisers to keep your pots at the necessary height!
