Hydroponic Perlite

Harvest Hero Hydroponic Perlite is adaptable to a variety of growing environments and systems, but also can be used as an amendment for container plants, root cuttings, and field and garden grown plants.

Versatility in Hydroponics

Perlite can be scaled up easily to meet the needs of increased production. Perlite is used to grow small-leafed crops such as micro-greens in conjunction with Nutrient Film Technique (NFT). For larger crops, perlite is ideal for use with modular systems such as “Dutch” or “Bato” buckets and perlite-filled “Grow-bags.”

Hydroponic Systems

  1. Fill container with Hydroponic Perlite.
  2. Set plant at conventional height so that the root system is reinforced.
  3. For even greater performance, use fertigation sleeves filled with Hydroponic Perlite.

Container Plants

  1. Mix a ratio of 30% Hydroponic Perlite with 70% peat moss.
  2. Saturate mixture with water.
  3. Place plant in mixture at original depth.
  4. Hydroponic Perlite can be used to facilitate better drainage in humid environments.

Root Cuttings

  1. Add full strength Harvest Hero Hydroponic Perlite into trays or cutting flats.
  2. Water well, place cuttings into trays and put trays in a shaded area.
  3. Cover tray in a white plastic trash bag to retain moisture.
  4. Check to remove any falling or mildewing cuttings to prevent contamination.

Field | Garden Grown Plants

  1. Harvest Hero Hydroponic Perlite can be mixed directly into field/garden soils to create a porous, well-drained soil which allows roots to breathe and stop soil compaction.
  2. Mix 10-20% Harvest Hero Hydroponic Perlite into your garden soil to provide adequate oxygen to the roots.
  3. Perlite is a mined mineral that resists degradation and retains its beneficial granular shape.

Soil Media Backed by Science


Domestically Sourced Perlite (100%)

Perlite is an industrial mineral formed by molten (magmatic) rock, also known as volcanic glass. It has been a key player in the horticultural industry for decades. The biggest benefit of expanded perlite is that it provides space for both air and water within a soilless mix. In fact, perlite retains water in three ways: in between individual grains, in channels leading to the cores of the grains, and on the highly irregular surfaces of each particle.

Additionally, perlite miraculously soaks up moisture against the opposing force of gravity, and it lets excess moisture drain out to just the right level for plant roots. Water mobility in perlite is excellent regardless of initial moisture levels due to relatively fast-acting capillary action. In a study completed by the Perlite Institute, a column of a blue-tinted liquid rises highest in perlite when compared to other commonly used growing media like mineral wool, pine / sawdust, and pumice.

Additional benefits of perlite include:

  • Naturally occurring
  • Improves moisture retention
  • Maintains consistent aeration and drainage for plant roots
  • Prevents compaction
  • Will not decompose over time, depleting soil nitrogen
  • Sterile—free of weeds, diseases, and pests
  • Lightweight, and ready to use
  • Neutral pH—a reliable constant when mixing with organic materials

The Grower’s Guide to Enhanced Perlite Mix

Whether you’re a pro in the garden or you’re just getting started, Harvest Hero can help you figure out how much Enhanced Perlite Mix you’ll need to ensure a robust crop. We’ve carefully crafted the ideal amounts of Harvest Hero Enhanced Perlite Mix you’ll need based on how many plants you’re planning to grow. The calculations in the following chart use a “middle of the road” approach. They’ll work in most instances, but we’ve erred on the side of possibly too much to avoid the mistake of not having enough to sow your next crop.
