PRO-MIX HP Growing Medium with Mycorrhizae, 2.8 cu ft

Pro-Mix hp with mycorrhizae is a high-porosity peat-based growing medium, and is well suited to growing plants which require lots of air and water. It is light and easy to work with and it even aids in stronger plant development through natural ingredients and beneficial fungi.

High Porosity for Better Drainage

PRO-MIX HP is a short form of "High Porosity. This indicates that the mix has more air space than regular soil. This allows water to pass through the soil much more easily, so the roots are not sitting in soggy soil. And at the same time, it holds just enough moisture for healthy growth. It’s a great option for gardeners who want more precise control over watering.

Made with Mycorrhizae for Healthy Roots

PRO-MIX HP contains Glomus intraradices, an endomycorrhizal fungus which colonizes plant roots, improving the absorption of water and nutrients. It spreads through the growing medium and enables roots to take up water and nutrients more efficiently, especially phosphorus and other minerals plants require for growth.

Lightweight and Easy to Use

PRO-MIX HP is lighter than regular soil as it is composed of peat moss and perlite. This makes it easier to handle, pour and use in pots, trays or growing beds. The loose texture also allows roots to expand more easily.

Ingredients and Composition

Every ingredient in PRO-MIX HP is there to promote healthy plant growth and to make gardening less of a hassle.

Canadian Sphagnum Peat Moss

• Holds moisture.
• Improves soil texture.
• Makes the mix light and airy.

Coarse Perlite

• Adds air spaces to the mix.
• Improves drainage.
• Helps prevent water from pooling around roots.

Dolomitic Limestone

• Balances the pH level of the mix.
• Keeps the growing medium in the ideal pH range for most plants (5.8 to 6.2).

Endomycorrhizal Inoculum (fungus)

• Boosts root growth.
• Helps roots absorb more nutrients and water.
• Supports overall plant health naturally.

The general mix is composed of approximately 70–75% peat moss and 25–30% perlite. For strong, healthy roots, this mix provides a balance of water retention and air movement.

Why Mycorrhizae Are Important

Mycorrhizae encourage roots to grow longer and stronger. They form a web that draws more water and nutrients from the soil. Mycorrhizal plants tend to grow faster, look greener and handle stress better than those without mycorrhizae. They require less fertilizer, which saves money over the long run.

How to Use the Product

Check out these tips to get the most from the PRO-MIX HP.

1. Gently scatter the mix in pots or in trays. Just don’t squish them down super tight.
2. Water the plants until water runs out the bottom. Water again once the top layer has partially dried.
3. Start with a light nutrient solution (25-50% strength) and increase as plants grow. Mycorrhizae reduce the need for a lot of fertilizer.
4. The mix is already ph-balanced, but it’s a good idea to test it once a month to make sure it stays in the right range.

Great for Water-Sensitive Plants

Plants such as African violets, orchids and succulents will grow root rot if they sit in damp soil. PRO-MIX HP dries out quickly and doesn’t retain more water, so it’s safer for these tender types.

Helps with Drought Stress

Plant roots can access the soil’s water more deeply thanks to the mycorrhizae. This helps plants stay healthy when they do not receive water every day, so it can be especially useful for busy growers or in warm climates.

Good for the Environment

This item is made with sustainability in mind.

• Made with renewable peat moss.
• Less need for chemicals.
• Lighter weight.

Packaging and Storage

Details on how it’s packed and stored for best performance.

• Bag size: 2.8 cubic feet (about 80 liters)

• Storage: Keep in a cool, dry place. Also keep the bag sealed when not in use to ensure the mycorrhizae does not spoil.

Summary

PRO-MIX HP Mycorrhizae offers a solution when looking for the best growing medium. It encourages rapid root development, helps to prevent disease in the plant, and ensures stable growth. Whether growing flowers, vegetables, or herbs, this mix will make growing easier and more productive.
