Horticultural and Hydroponic Applications
Growstone manufactures substrates and aggregates engineered to meet the specific needs of different horticultural communities. See how our products can be used to build a hydroponics system, as a soil amendment to improve structure and to build the best soil for water retention and aeration. Or use as a reusable plant growing medium in commercial, container garden, and landscape applications.
A Green Product
Growstone horticulture products reduce environmental impact at both ends of the production chain. They replace strip-mined materials like pumice, perlite, and stonewool, reducing environmental degradation. At the same time, since the product largely consists of recycled bottles, a large amount of waste material is given a new life, keeping it from the landfill.
Growstone's sister company Earthstone International was started by co-founders and eco-preneurs Andrew Ungerlieder and Gay Dillingham in 2003. In 2004 the company began developing a horticultural product line. Using patented technology, waste glass is being transformed into engineered horticultural products that are environmentally friendly and effective.
Field-Tested
Growstone is focused on providing not only an environmentally responsible product line, but also one based on sound science and technology. Extensive horticultural trials in association with universities are continuing in both traditional and hydroponic greenhouses, as well as containerized nurseries. Data show that Growstone products can be an effective and eco-friendly part of hydroponic systems, and serve as an effective soil amendment, in a variety of climate zones and environments.
