PRO-MIX® HP® MYCORRHIZAE, Soilless Potting Mix (3.8 cu.ft.)

High-air, fast-draining soilless mix for propagation and greenhouse growing

PRO-MIX® HP® MYCORRHIZAE is a peat-based growing medium for growers who need strong aeration, extra drainage, and lower water retention than a general-purpose peat mix. The 3.8 cu. ft. bale is suited to greenhouse vegetables, transplants, young plants, ornamental containers, and controlled-environment growing.

Why growers choose PRO-MIX HP

• High porosity: Coarse perlite and fibrous peat help create air space around developing roots.
• Extra drainage: A lower water-holding profile gives growers more flexibility to manage irrigation and dry-back.
• Mycorrhizae included: Contains beneficial endomycorrhizae for the root-zone environment.
• Useful across crops: Suitable for annuals, foliage plants, potted flowers, greenhouse vegetables, vegetable transplants, and propagation.
• Large compressed bale: Provides 3.8 cu. ft. of soilless medium for larger planting programs.

What is in the mix?

• Sphagnum peat moss, approximately 65–75%
• Perlite
• Calcitic and dolomitic limestone
• Wetting agent
• Beneficial mycorrhizae

How to use

Open the bale and loosen the mix in a clean tub or container. Lightly break up compressed material, then add a small amount of water if needed so the mix is evenly moist but not saturated. Fill flats, pots, or containers without packing the medium down, plant your young plants, and water in thoroughly. Adjust irrigation and feeding to your crop and environment.

PRO-MIX HP is a soilless medium, not a complete fertilizer. Use a nutrient program appropriate for your crop and growing system.
