premier pro mix hp mycorrhizae

Each bag contains 2.8 cubic feet. Reported weights for the 2.8 cu ft bags range from 26.5 to 33 pounds; listings also show a capacity of about 83.7–84 quarts.

'High porosity' means the media has high air capacity and extra drainage, helping root oxygenation and watering flexibility to support optimal plant growth.

The added mycorrhizae form a symbiotic relationship with roots to enhance nutrient and water uptake, increase stress resistance, and improve overall root and plant health.

They are described as all‑purpose mixes suitable for a wide variety of horticultural plants, including water‑sensitive crops, rooting cuttings, and low‑light growing conditions.

The mix combines high porosity and extra drainage (via perlite) with a beneficial mycorrhiza inoculum. This promotes root oxygenation and consistent moisture handling while improving nutrient and water uptake—traits that support rooting cuttings and benefit water‑sensitive crops.

The mycorrhizae are reported to increase water and nutrient acquisition, with listings specifically calling out improved uptake of phosphorus, copper, and zinc.

Listings show one bag per purchase, and each bag is 2.8 cubic feet in volume.
