Pumice 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.
