Can Perlite be Used in Hydroponic Systems?
It’s possible to grow most plants in perlite alone, although usually the finer grades and medium grades will work better and require less water. Seeds can be started in any grade of perlite, but with smaller seeds, finer grades of perlite would be recommended. Our Hydroponic Perlite is an excellent soil substrate that is 100% sterile growing medium and OMRI listed.
What is Harvest Hero Enhanced Perlite Mix?
Harvest Hero is a specialty soil media manufacturer. Our flagship, patent-pending, 3-in-1 blend, comprised of perlite, diatomaceous earth, and essential nutrients, promotes superior growth of your plants by providing essential nutrients during vegetative growth. Using Harvest Hero Enhanced Perlite Mix takes the guess work out of home growing while improving crop production and yields.
How does Harvest Hero Enhanced Perlite Mix work?
The Harvest Hero Enhanced Perlite Mix mechanism is 4-fold:
- Promotes excellent gas exchange through the incorporation of horticultural perlite by aerating the soil profile to reduce compaction.
- Supplies a suitable substrate for beneficial soil microbes to multiply.
- Provides macronutrients for young plants or transplants.
- Contributes diatomaceous earth, a form of soluble silica, that increases nutrient uptake, improves water holding capacity, and provides a strong, abiotic stress-resistant foundation for plants to thrive.
How long does the nutrients last in Harvest Hero Enhanced Perlite Mix
Harvest Hero Enhanced Perlite Mix has 2 macronutrients in the mix — phosphorus and potassium and is expected to last 6 – 8 weeks or even up to 1 year depending on the plant. The phosphorus and potassium stays put in the soil column until it’s ready to be used by the plants. If the plants are heavy feeders, expect a shorter cycle compared to a normal plant which requires only minimal amounts of phosphorus and potassium. With a normal plant, the nutrients can last up to one year. If you’re growing cannabis, which is considered a heavy feeder, expect the nutrients in the Enhanced Perlite Mix to last 6 months if you mix 20% of Harvest Hero with potting media.
How much Harvest Hero Enhanced Perlite Mix should I expect to amend in a potting soil?
One 8-quart bag of Harvest Hero Enhanced Perlite Mix will supply approximately a 7-gallon container at the prescribed mix ratio. One 12-quart bag of Harvest Hero Enhanced Perlite Mix will supply approximately a 10-gallon container at the prescribed mix ratio.
How is Harvest Hero Enhanced Perlite Mix used and what is the prescribed mix ratio?
Harvest Hero Enhanced Perlite Mix is custom blended to be added in conjunction with sphagnum peat moss at a rate of 20-30% by volume. This product also reduces the total weight of the soil – allowing for less expensive shipping costs. Harvest Hero Enhanced Mix can be used for house plants, fruit and vegetable plants, orchids, lilies and is especially well-suited for cannabis gardening in containers.
One 8-quart bag of Harvest Hero Mix supplies approximately a 7-gallon container at the prescribed mix ratio. One 12-quart bag of Harvest Hero Mix supplies approximately a 10-gallon container at the prescribed mix ratio.

Will I need to use additional fertilizers after the initial 4-6 week starting period?
After the initial four to six-week growth period, you could begin your own specialized fertilizer program. The fertilizer ingredients you use will be dependent upon whether you want to remain in vegetative growth or initiate a flowering response.
However, there are additional growing measures that will work in harmony with Harvest Hero, such as an additional nitrogen source. If the seedling appears to lose its dark green color, apply ½ seaweed solution (use ½ strength of bottle recommendations) sprayed on the young seedlings. The seaweed will supply additional energy and minerals to the seedling and restore the dark green color. Harvest Hero will supply sufficient amounts of potassium and phosphorus and promote strong, healthy roots, stems, and leaves. Be sure to keep the soil moist at all times during the germination phase.
Is Harvest Hero Enhanced Perlite Mix toxic or contain any GMO’s?
Harvest Hero Enhanced Perlite Mix contains no genetically modified organisms (GMOs). The product is composed of entirely natural ingredients plus the addition of essential nutrients. For greater detail, please download our safety data sheet (SDS).
Why do I see the occasional algae layer on my soil media and what does it mean?
Algae on soil surfaces represent no issues unless it becomes thick (2-5mm). Once it gets thicker than 5mm, it may impact soil gas exchange, though it is highly unlikely. Algae growth on the soil surface is typical and found on all soil surfaces exposed to adequate light sources. The exception being plants grown entirely in aseptic environments (they would exhibit no algae growth).
Algae on soil surface causes no pathological response to plants. It may be a source of carbon/carbohydrates for fungus gnats but with silica present, in the Harvest Hero, it becomes a non-issue. There is actually a positive symbiotic relationship between the plant, the roots, and the surface algae, and it is just another component of a healthy soil ecosystem.
Can Harvest Hero Enhanced Perlite Mix be used with aquaponic systems?
It’s not advised to use Harvest Hero Enhanced Perlite Mix in aquaponic systems because the water-soluble nutrients become too readily available and could cause over-fertilization. However, we recommend using Harvest Hero Hydroponic Perlite for hydroponic systems. Perlite is an excellent soil substrate that is 100% sterile growing medium and is OMRI listed.
Can I use Harvest Hero Enhanced Perlite Mix to improve soil conditions for increased plant vigor with sleepy ornamentals in my yard?
Mix in 20-30% Harvest Hero Enhanced Perlite Mix with peat moss. Remove soil around the drip line of the plant you want to revive. Take a band of soil from around the root ball approximately 6-10 inches deep by 5-8 inches wide. Be sure to not disturb the existing root system. Replace the native soil with Harvest Hero Enhanced Perlite Mix. Water well and keep moist for 2 weeks. You should see a flush of new growth in 10-15 days.
Can I use Harvest Hero Enhanced Perlite Mix to propagate and root cuttings?
Harvest Hero Enhanced Perlite Mix is an excellent substrate for the development of new roots from cuttings. Use Harvest Hero Enhanced Perlite Mix at full strength, without adding peat moss. Place cuttings into the Harvest Hero Enhanced Perlite Mix after dipping the cut end in rooting hormone. Water the Harvest Hero Enhanced Perlite Mix well and keep moist. Gently supply bottom heat with a soil heating pad, cover the planting container with a plastic dome to prevent moisture loss, and keep fresh cutting away from direct sunlight.
Storage and Handling
To prevent possible contamination of your Harvest Hero products, please follow these guidelines:
- What is the shelf life for Harvest Hero Enhanced Perlite Mix?
Harvest Hero Enhanced Perlite Mix can be stored indefinitely if the product is kept dry. This product will not lose effectiveness or potency when stored over time. Keep Harvest Hero products clean and dry until use. Moisture will not degrade Harvest Hero products, but it will make it difficult to unload and may separate some of the material. Harvest Hero products do not contain any organic content. However, allowing water to absorb into the material may promote the growth of mold or other organic materials.
- Keep the products away from odors
Harvest Hero products exhibit a porous, microscopic structure, which allows for the retention of small amounts of liquids and/or gases on their surface. If you store the product next to products that have strong odors, it is quite common for Harvest Hero products to pick up these odors.
- What to do if your Harvest Hero Product becomes contaminated
You can dry Harvest Hero products and they should return to their original properties. Similarly, you can remove odors by applying heat. This is of course, inconvenient, and potentially costly, so please prevent contamination by using proper storage guidelines.

What benefits can be achieved by using Harvest Hero Enhanced Perlite Mix?
Harvest Hero’s 3-in-1 Enhanced Perlite Mix increases the oxygen levels in the soil and the soils ability to drain excess water while eliminating soil compaction. It also maintains soil pH levels, supplies essential nutrients during vegetative growth, while strengthening the plant’s cell wall, creating a soil environment favorable for microbial growth, larger plant yields, including flower and terpene production in cannabis plants.
Your product claims to “promote increased flowering, enhanced terpene development, and larger overall yield,” compared with other soil amendments. What data can you share to support this?
Harvest Hero improves soil conditions to promote root growth and nutrient uptake levels in various soil compaction densities. Nutrient flow in plants is directly related to gas exchange, which is also directly related to soil compaction. Perlite reduces soil compaction and offers porosity and an accompanying increased ability for air/gas movement.
Compared to a standard perlite and sphagnum peat moss mix control group, Harvest Hero Enhanced Perlite Mix resulted in:
- Improved Soil Conditions Increased THC Total Yield
- Improved Soil Conditions Increased Dry Flower Weight
- Improved Soil Conditions Increased THC
- Improved Soil Conditions Increased Total Cannabinoids
- Improved Soil Conditions Increased Terpenes
- Improved Soil Conditions Increased Leaf Weight
- Improved Soil Conditions Increased CBD Total Yield
- Improved Soil Conditions Increased Stem Weight
- Improved Soil Conditions Increased Dried Flower Weight
- Improved Soil Conditions Increased Root Mass
Most sterile, inorganic soil media can be used for hydroponic growing. Why can’t Harvest Hero?
Harvest Hero Enhanced Perlite Mix cannot be used for hydroponic growing because the essential nutrients will become instantly soluble in the water, creating too much fertilizer availability and subsequent burning of the plant roots. However, you can use Harvest Hero’s domestically sourced perlite, vermiculite, and diatomaceous earth for your hydroponic growing needs by completing a special order request form.
Can Harvest Hero Enhanced Perlite Mix be used in outdoor soils?
Harvest Hero Enhanced Perlite Mix can be used to amend outdoor soils, gardens, and basically any place where you would grow a tree, bush, plant or shrub. Just incorporate a 10-20% mixture of Harvest Hero Enhanced Perlite Mix with the native soil (depending on soil type). This will increase drainage, increase the soil’s ability to hold oxygen, supply fertilizers and nutrients for the young plants.
Will Harvest Hero Enhanced Perlite Mix affect how much I water my plants?
You may find you will spend less time watering your plants. Harvest Hero Enhanced Perlite Mix allows for greater water holding capacities in the soil while making the nutrients readily available for growth.
What is the Difference Between Coarse Perlite & Harvest Hero Hydroponic Perlite?
The main differences between coarse grade and medium grade perlite is the particulate size. Coarse perlite is 2mm or greater and medium perlite is 1.5mm or less in size. Also, the smaller sized perlite has more surface area, whereas the larger sized has more pore space between particulates. The larger grades also have less bulk density when compared to smaller grades. Coarse grades can be used in medias requiring a higher rate of water drainage. Its best used for plants, such as cactus and succulents which prefer dryer soils.
Harvest Hero Hydroponic Perlite has the best particulate size to promote good root development and maintain soil moisture for robust growth. When using Harvest Hero Hydroponic Perlite, watering cycles become less frequent. A coarser grade of perlite requires frequent watering, sometimes needing to be watered 2 or 3 times a day compared to watering 2-3 times a week when using Harvest Hero Hydroponic Perlite.
Does Harvest Hero Enhanced Perlite Mix contain mycorrhizal fungi or lime?
Harvest Hero Enhanced Perlite Mix doesn’t contain mycorrhizal fungi or lime. The patent-pending 3-in-1 blend contains high porosity perlite, diatomaceous earth, and essential nutrients. The mycorrhizal and lime, however, does work in harmony with Harvest Hero Enhanced Perlite Mix as it improves fertilizer uptake which also helps you to save on nutrient costs in the long-term if you’re doing larger grows.
Can Lump Charcoal be Used Instead of Perlite to Ensure Excellent Drainage?
Lump charcoal helps with pH fluctuations and is a good carbon source that creates a surface for beneficial microorganisms to live on. However, it doesn’t provide any nutrients, soil porosity or gas exchange in the soil. Perlite, on the other hand, provides excellent gas exchange by aerating the soil profile to reduce compaction. Also, perlite increases plant vigor by delivering excellent drainage with increased oxygen uptake.
Are the Nutrients in Harvest Hero Enhanced Perlite Mix Enough to Satisfy the Demands of Faster-growing Crops?
The nutrient profile in Harvest Hero Enhanced Perlite Mix is engineered to satisfy plants’ vegetative growth requirements (generally within 4-6 weeks). For faster-growing consumable crops such as leafy greens, the availability of nutrients is essential to generate robust growth. We recommend adding a balanced water-soluble fertilizer like Maxigro to ensure the availability of nutrients for vigorous growth.
What Steps Can I Take to Avoid Root Tip Burn?
Urea-based fertilizers (46-0-0) are very acidic and too strong for young, tender roots. We recommend using a calcium-based fertilizer (15-0-0) instead. For example, YaraLiva (YaraTera) Calcium Nitrate- 15-0-0 blend will produce the available nitrogen needed to finish a crop that takes less than 35 days to finish.
What Nitrogen-based Fertilizer Works in Harmony with Harvest Hero Products?
We suggest using calcium nitrate (15-0-0 at 275ppm) and mixing with a well-rounded fertilizer profile (such as 10-5-14) engineered for fast-growing plants. For example, GH MAXIGRO 10-5-14 at 120ppm with the Harvest Hero Enhanced Perlite Mix. Mix both solutions and combine the two to make your stock solution. If mixing Harvest Hero products with Coco Coir, add Maxicrop seaweed to color the stock mixture. This should compensate for the high carbon to nitrogen ratio of the coco fiber.
What Must I Consider When Mixing Harvest Hero with Coconut Coir or Coconut Fibers
There are several considerations that impact the robust growth needed to grow shorter lifecycle plants (such as leafy greens). When mixing Harvest Hero products with coconut fiber or coconut coir, the coco has a carbon to nitrogen ratio of close to 90 parts carbon to 1 part nitrogen. Soils containing peat moss, for example, have a carbon to nitrogen ratio of 20:1, which is the preferred carbon to nitrogen ratio. When carbon to nitrogen ratios are higher than 20:1, nitrogen is bound and used to decompose the organic substrate, meaning the nitrogen being applied to the crop is bound to the organic component in the media. To be successful when using coco coir products in growing media, one needs to increase the applied nitrogen to compensate for the increased carbon to nitrogen ratios.
How can Harvest Hero be used with Peat Moss or Coco Coir without a pH adjuster being involved?
We recommend using Canadian Sphagnum peat moss, which is just slightly acidic. pH values for Canadian Sphagnum peat moss are well within the acceptable ranges of cannabis culture. Be mindful, Diatomaceous Earth (DE) is slightly alkaline in nature, which will have a buffering effect over the slightly acidic nature of Canadian Sphagnum peat moss, rendering the mix neutral pH.
What would you recommend for raised garden bed directions for use for Harvest Hero Enhanced Perlite Mix?
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.
If applicable, how and when do I submit a sales tax exemption form?
If your purchase is exempt from sales and use tax, please forward a copy of your exemption certificate to SalesTaxExemption@harvesthero.com. Please make out the Vendor/Supplier to be Dicaperl Minerals, LLC.
Can Harvest Hero Enhanced Perlite Mix work for cactus and other succulents?
Harvest Hero Enhanced Perlite Mix will do a great job keeping cacti and succulents hearty. Use a 50/50 blend of Harvest Hero Enhanced Perlite Mix with peat moss. This will supply excellent drainage and good root gas exchange.
Can I store over-winter bulbs and corms such as dahlias, gladiolas, calla lilies and Dutch bulbs like tulips in Harvest Hero Enhanced Perlite Mix?
Use pure Harvest Hero Enhanced Perlite Mix to store all your dry bulbs for the winter. Dig bulbs in fall, after the foliage dies back. Dry the bulbs on paper for 5 days and place the dried bulbs into plastic bags containing dry Harvest Hero Enhanced Perlite Mix. Mark the plant names on the bag and place the resting bulbs in a cool, dark place. They will be ready for planting come late winter or early spring.
Can I use Harvest Hero Enhanced Perlite Mix to improve soil conditions that promote new growth on old fruit trees, ornamental trees and shrubs?
Harvest Hero Enhanced Perlite Mix works well to improve soil conditions that promote new growth on trees and shrubs. Take a 2-inch diameter dowel or old garden shovel handle and pound this into the soil, along the drip line of the tree or shrub approximately 10-15 inches deep. Fill the hole created by the dowel with pure, un-blended Harvest Hero Enhanced Perlite Mix. This treatment will aerate the soil and supply nutrients to the root zone, where the tree or shrub will have direct access to the newly available fertilizers.
Should I use Harvest Hero Enhanced Perlite Mix when I re-pot my container plants?
Most container plants require re-potting every year. The best procedure is to remove the plant from the container when the soil is somewhat dry, brush the loose soil off the plant’s root ball, then mix 20-30% of Harvest Hero Enhanced Perlite Mix with peat moss and blend well. Set the root ball in a container at the original depth, making sure not to set the root ball too deep but exactly at the original soil depth. Fill the new container with the freshly blended Harvest Hero Enhanced Perlite Mix, being sure to slightly firm the new soil mixture into the container. Leave the fresh soil mixture 1 inch from the top of the container to allow for watering.
Can Harvest Hero Enhanced Perlite Mix be used in commercial greenhouses and grow operations?
Harvest Hero Enhanced Perlite Mix is well suited for commercial and industrial use. Its cost-effective benefits will allow growers to realize greater profit margins. Commercial cannabis growers will improve their soil conditions promoting higher yields, increasing terpene and THC levels, and reduce potting soil costs.
Can I re-use the soil after harvesting my plants?
It is not advised to recycle or reuse Harvest Hero Enhanced Perlite Mix due to the inclusion of essential nutrients. To ensure your plants receive the highest level of nutrition, it is advised to use fresh product for every cropping cycle to guarantee adequate supply and delivery of essential nutrients.
Will mixing Harvest Hero Enhanced Perlite Mix with Coast of Maine Bar Harbor Blend organic potting soil make the soil too “hot”?
The amount of nutrients contained in Coast of Maine Bar Harbor blend releases very slowly. When Harvest Hero Enhanced Perlite Mix is added, there should be no problems with hot levels of phosphorus and potassium. We recommend adding no more than 20% of Harvest Hero and you’ll have a superior product with enhanced soil performance.
Also, because Harvest Hero Enhanced Perlite mix is not 100% organic, when you mix both Harvest Hero Enhanced Perlite Mix with Coast of Maine Bar Harbor blend organic potting soil, it will not retain the organic profile.
