Two new horticultural substrates presented

Dicalite Management Group introduces the second and third products from Harvest Hero, a brand of soil amendments and growing media targeting the cannabis industry and overall horticultural market.

Harvest Hero Perlite + Silica
The latest product release comes during a time of increased demand for soilless substrates in hydroponic environments, vertical farming, and traditional horticultural markets. To satisfy these demands, Dicalite's product development team focused on the use of diatomaceous earth, a naturally occurring mineral comprised of soluble silicon, an American Association of Plant Food Control Officials (AAPFCO) beneficial plant substance. The silicon, or silica, helps to fortify plants' cell walls, creating a stress-free environment for growers' plants. Perlite+ Silica features a natural, disease-free soilless substrate that mitigates greenhouse insects, increases node and flower development, and requires less nutrition solution.

In 2021, University of Kentucky researchers tested Perlite+ Silica to evaluate the influence of diatomaceous earth-coated perlite on the growth and yield of greenhouse-grown parthenocarpic beit alpha (mini) cucumbers. A University of Kentucky Researcher said: "When trialing the Perlite+ Silica, we observed fewer greenhouse insect pests such as fungus gnats and shore fly larvae and adults. Cucumber plants grown with Perlite+ Silica were determined to have an increased number of nodes per plant and required ~21% less nutrient solution than control plants. Therefore, the addition of silicon assisted with reduced water requirements during summer production. Additionally, the Perlite+ Silica provided a level of buffering capacity to maintain an optimal root-zone pH."

Harvest Hero hydroponic perlite
Harvest Hero is also debuting their OMRI-listed Hydroponic Perlite, a natural, soilless growing medium designed to increase yields for hydroponic growers and systems. Hydroponic Perlite features a 100% sterile growing medium, free from weeds, insects, and disease to ensure a 100% consistent product. Hydroponic Perlite aims to increase plant vigor due to its oxygen uptake and water drainage and can represent cost savings to the grower in the form of water conservation and fertilization costs.
