Diverse Applications for our High Performance, Sustainable Products

Growstone’s patented process creates horticultural, commercial, and consumer products with customizable properties. Our successful trials with Universities and industry professionals has led to new products and processes.

Growstone is also continuing research in other market sectors as varied as green technology building materials, green roofs, water filtration, and advanced hydroponic growing systems. Growstone’s proprietary green technology and physical characteristics such as pore size, pore structure, abrasiveness, and hardness can be customized to satisfy a wide range of plant and climate growing requirements in different growing systems.


Growstone manufactures substrates and aggregates engineered to meet the specific needs of different horticultural communities including floriculture, greenhouse and nursery, and commercial hydroponics. Products can be used in hydroponics systems and as a soil amendment, in commercial, container garden, and landscape applications.


Growstone has created products for hydroponic growing systems, for use in both commercial and home hydroponics growing. A reusable plant growing medium, the material can be steam sterilized and used again or simply added to soil to improve texture, structure, and aeration. Growstone is the first major product development in this arena in over 20 years.

Soil Amendment

Growstone products are an alternative to perlite, and other soil amendments. They help commercial and home gardeners create the best soil for water retention and aeration. Growstone has products for container gardening, the floriculture business, greenhouses and nurseries. Growstone products are competitive in price and effectiveness with established soil amendments in the home and commercial horticulture markets.

Green Building Material

Growstone is a green technology building material that offers lightweight, bulk density and a high surface area for use as an aggregate and as a substrate.


Growstone material is a high strength, lightweight aggregate that has chemical compatibility with cement.

Green Roof Research

Growstone can be an integral part of green roof systems. Its lightweight, superior water retention properties, and strength make it a promising alternative to other green technology building materials used for biodiverse green roofs. Research is ongoing for the use of Growstone as an integral part of green roof systems. Its light weight, superior water retention properties, and strength make it a promising alternative to other green technology building materials used for biodiverse green roofs.


Structurally rigid and strong enough to handle high pressure, Growstone material can be used for a variety of filtration applications. A rigid foam with pores, the material has a high surface area, whether used in a particulate or block form.

Growstone material can be used as a structural substrate and coated with ion exchange resins. Uncoated, it is still naturally compatible against most acids used to remove pollutants or contaminants in common water filtration applications. Filtration applications in the petrochemical industry and nuclear waste processing are also being investigated.
