Reusable medium great for flood and drain or NFT hydroponic systems. Clayballs are the perfect medium to use in your Aquaponic grow beds also.
THE GROW SHOP PRODUCT TIP: WHEN FINISHED WITH YOUR CLAYBALLS SOAK IN A DILUTED MIX OF HYDROGEN PEROXIDE TO STERILISE. USE A HIGH PRESSURE SPRAY TO REMOVE OLD DEAD ROOTS. LET THEM DRY AND THEY ARE THEN READY TO BE USED AGAIN.
