Horticulture: Soilless Grow Media

ULTRA-EFFICIENCY SOILLESS GROW SYSTEMS demand high-performance grow media. Ponics Stone™ delivers in the key areas of stability, nutrient holding capacity, gas exchange, drainage, weight, media particle size, crop balance and media life.

With the rising popularity of high-efficiency growth systems, especially aquaponic systems, pumice provides every advantage as a soilless grow media.

Why Ponics Stone? Ponics Stone hits the right notes on each of the following key considerations:

NUTRIENT HOLDING CAPACITY—an effective grow media must have the ability to retain that nutrient-rich water for a time, making it continuously available to the roots between watering cycles.

DRAINAGE—balance is so important: a grow media must be able to shed water quickly to allow air into the root zone, yet retain enough nutrient-rich moisture between irrigation cycles to fuel rapid growth.

GAS EXCHANGE—a grow media must allow free-flowing exchange of oxygen and carbon dioxide in the root zone.

STABILITY—the grow media must be substantial enough to support a plant’s root system, as it is the root system that support the plant and the fruit it bears.

WEIGHT—grow beds tend to be positioned above ground/floor level to allow a water tank underneath and/or to provide easy access when planting and harvesting, and that means grow media weight is an issue.

CROP BALANCE—a grow media must provide good drainage, excellent moisture retention, and increased gas exchange necessary for both vegetative and reproductive (fruit) growth.

LONG MEDIA LIFE—to be able to repeatably replant in the same grow media saves time and money.

SUSTAINABLE AND GREEN—Ponics Stone™ is not manufactured. It is 100-percent pure, natural pumice. The entire suite of pumice’s useful properties were bestowed by nature, and the process to prepare Ponics Stone™ for market is simple, sustainable, and green.
