Why Growstones are the Perfect Growing Medium:

Growstone Hydroponic Substrate is the perfect growing media for use in hydroponic growing systems as simple as manually irrigated containers, or as advanced as automatically drip irrigated containers, Ebb-Flow systems, and NFT tables. It replaces strip-mined materials like Hydroton or stonewool, reducing environmental degradation. Growstones are designed to allow for rapid moisture absorption and enhanced drainage and oxygenation.
• Proven 3.5 times more water absorption then Hydroton
• Reusable, lightweight and easy to work with
• No clay dust in your reservoir – rinses clear without residue
• Made in the USA, a sustainable and earth-friendly option
