Proven to Deliver Results

This patent-pending mix was designed by agronomists to improve soil structure for nutrition which promotes bigger plants and bigger yields. In fact, a study done at North Carolina State University (which focused on cannabis plants) showed improved soil structure that resulted in dramatic increases in plant height, stem diameter, root mass, and yield.

Harvest Hero Enhanced Perlite Mix will meet your plants’ needs throughout those critical initial vegetative growth weeks by improving soil quality, providing plant nutrients, and amending soil properties to make it easier for the plant to absorb and translocate essential plant nutrients to the root system.

Consisting of domestically sourced perlite, diatomaceous earth, and essential nutrients, Harvest Hero’s 3-in-1 Enhanced Perlite Mix is unlike anything on the market today.

Save Big With Harvest Hero

Our proprietary blend of perlite, diatomaceous earth, and nutrients isn’t just proven — it’s cost effective as well. Take a look at the chart below and see how our Enhanced Perlite Mix delivers more value for your money than separately purchased components.


Harvest Hero Enhanced Perlite Mix is a revolutionary, patent-pending, 3-in-1 soil substrate formulated to jump-start your crop!

Harvest Hero Enhanced Perlite Mix is specially formulated to enhance your standard growing media to produce ultra-luxuriant growth, appearance, and fragrance in your potted specimen. This proprietary blend of perlitediatomaceous earth, and essential plant nutrients will improve your soil quality, helping your plants get the nutrition they need, ensuring robust, vigorous growth.

Potting Soil

  1. Mix a ratio of three (3) parts Harvest Hero Enhanced Perlite Mix to ten (10) parts coco coir or peat moss. No need to add fertilizers in the initial vegetative growth weeks. Harvest Hero Enhanced Perlite Mix has everything your plants need to thrive during the vegetative stage after planting.
  2. One eight-quart (8qt) bag will supply approximately a seven-gallon (7gal) container at the prescribed mix ratio.
  3. One twelve-quart (12qt) bag will supply approximately a ten-gallon (10gal) container at the prescribed mix ratio.

Root Cuttings

  1. Mix a ratio of five (5) parts Harvest Hero Enhanced Perlite Mix to ten (10) parts coco coir or peat moss.
  2. Saturate mixture with water.
  3. Make a hole in the mixture and insert the cutting.
  4. Press the mixture down around the cutting.

Root stimulators may be helpful in some instances. Keep mix wet and out of direct sunlight, preferably in a shaded location. Fertilizers are not necessary for the first four to six weeks.


  1. Mix a ratio of three (3) parts Harvest Hero Enhanced Perlite Mix to ten (10) parts coco coir or peat moss.
  2. Plant seed according to seed species directions. (Oftentimes, you’ll place the seed on top of the mix and cover with a thin layer.)
  3. Water well.

Raised Garden Beds

For raised-bed applications, we recommend a minimum of 10% Harvest Hero Enhanced Perlite Mix by volume. Ideally, the mixture rate could be increased to 30% depending on the bulk density of your compost, field soil, or dirt. For artificial blends such as peat moss and Enhanced Perlite Mix, a 10-20% Enhanced Perlite Mix inclusion rate allow for supra optimal growing conditions.

This mix may be used in trays for seedling beds directly on the ground. When the seed is well-established, transplant it to its final location.

Soil Media Backed by Science

Perlite, Diatomaceous Earth, and Essential Nutrients

Domestically Sourced Perlite

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
Natural Diatomaceous Earth

Diatomaceous earth (DE) is the naturally occurring fossilized remains of diatoms. It is a near-pure sedimentary deposit consisting almost entirely of silicon dioxide, one of the world’s most abundant elements, which is semi-soluble and essential for plant health. Silica improves cell wall strength and structural integrity. This allows diatomaceous earth to improve the soil quality while increasing resistance against abiotic plant stressors:

  • Drought
  • Waterlogging

It also aids in reducing salinity, promotes a neutral pH, adds matrix to the soil, and improves overall soil quality.

Essential Nutrients (0-0.57-0.57)

Harvest Hero’s Enhanced Perlite Mix is mindfully crafted with essential macronutrients for the first four to six weeks of growth. With a 0-0.57-0.57 grade, it is a significant source of potassium and phosphorus (with nitrogen provided by the organic matter in your soil choice of sphagnum, peat moss, or coco coir).

Nitrogen (N): Harvest Hero Enhanced Perlite Mix is strategically designed to be mixed with an organic soil amendment high in nitrogen (ideally plant-available nitrogen). As a result, Harvest Hero’s team of agronomist placed an emphasis on formulating a soilless mix with essential nutrients high in potassium (K) and phosphorus (P).

Potassium (K): This nutrient supports overall plant growth, activating dozens of important enzymes for protein synthesis, sugar transport, N and C metabolism, and photosynthesis.

Phosphorus (P): While this nutrient is essential for the general health of plants, it’s especially vital for root health: the basis of your seedling’s success. It is a key component of ATP (the energy unit of plants).

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.
