Growstone Hydroponic Substrate is the perfect growing media for vegetables, herbs, fruit and flowering plants – from lettuce and basil, to tomatoes, cucumbers, strawberries, gerbera daisies and orchids. It can be used in hydroponic systems as simple as manually irrigated containers, or as advanced as automatically drip irrigated containers, Ebb-Flow systems, and NFT tables. Features:
- Highly effective balance between air and water content at field capacity, meaning high air-filled porosity coexist with high water holding capacity.
- Growstones hold 3 times more water and 12% more air than Hydroton.
- Easy control of root zone moisture content – high steer-ability.
- Easy drainage and re-wetting after being completely dehydrated.
- Silica release in a form plants can uptake.
- Highly flexibility for different plant needs for consistent high yield.
- No weed seeds or disease spores.
- Reusability and lightweight.
- A sustainable and earth-friendly option.
