Here at Victory Hydro Gardening a new and improved hydroponic grow medium and soil additive has been catching on with many of our customers. Growstones are an outstanding alternative to hydroton and rockwool for hydroponic growers. It has great benefits as a soil additive as well since it gives 40% more aeration than perlite and it ads a constant silica leech into your plants root zone. To learn more please read the short article below and take the time to visit there website or stop by the store and we can tell you all about them!
The great advantage of porous media is its ability to provide simultaneously sufficient levels of oxygen and water to the roots. Water is mainly held in the small pore space of the medium while rapid drainage and air entry depends on the presence of large pores. So a good distribution of small and large pores is essential for a good growing medium.Growstones highly porous and uneven shaped aggregates provide just that - a balanced combination of small pores inside each aggregate and large pore spaces between aggregates. This determines Growstones capacity to store water, air, and the ability to provide them to the plants.
But what’s truly unique about Growstones is the combination of pore size distribution and pore interconnectivity. Pore interconnectivity results in a large surface area available for roots to grow in and around. While larger pores between aggregates, assure rapid drainage and air exchanges, which guarantees oxygen is rapidly dissolved in the water and supplied to the roots, small pores are filled with fresh air and covered by a film of oxygen-saturated water. As a result, after irrigation each pore acts as a ‘micro NFT system’. The combination of small and large pore spaces creates an ideal environment for roots, microorganisms, and worms to thrive, full of oxygen-rich water, and nutrients.
Growstones pore size and connectivity results in good wicking ability. Growstones absorb and retain moisture 4 inches above the water level. This wicking ability has multiple advantages, all associated with creating a constant moist and highly aerated environment for roots above the water level. These conditions promote continuous development of hairy roots, which considerably increase the absorption area of the root system. Growstones wicking ability also has practical implications on growing. With Growstones, in flood-drain tables the water level need only to be raised up to 2 to 3 inches below the surface of the medium. The upper layer of Growstones will keep moist and filled with air. This eliminates the possibility of excess moisture at the surface of the medium reducing chances for fungus gnat infestations and algae growth.
Growstones pore size and interconnectivity also facilitates horizontal water diffusion leading to uniform moisture distribution, which in turn induces uniform root growth allowing you to take advantage of the entire volume of growing medium you paid for.
From the growing management point of view, Growstones drier nature in comparison to other growing media has multiple advantages. It makes it easier to change root zone nutrients, pH and moisture levels as quickly as desired. As a result, with Growstone it is easy to transition your plants from vegetative to bloom. Being drier, also allows taking advantage of frequent feedings with no risk of over-watering or root rot, and it reduces plant’s susceptibility to Pythium and other fungal diseases.
Finally, because Growstones are made from recycled glass, its surface leaches out silica in a form roots can uptake - monosilicic acid (H4SiO4). Plants that accumulate silica have higher resistance to stresses such as drought, salinity heavy metals, and pathogens. In summary, with Growstones, roots have a larger available surface area, which retains water and loads of aeration at container capacity. Its unique pore structure promotes the growth hairy roots, assures uniform root growth through the entire medium, easy drainage, high leaching effect compared to other less clean substrates, leaving fewer residues behind. Its dry nature makes it easier to control moisture and nutrient levels, and to change them as quickly as desired making it easy to transition between development stages. It also reduces susceptibility to fungal diseases. For all these reasons, Growtones roots are not just healthier. They are healthier longer.
