PRO-MIX® HP® AGTIV® REACH™ High porosity growing medium 3.8 cu.ft.
Former name: PRO-MIX® HP® MYCORRHIZAE
PRO‑MIX HP with Mycorrhizae is perfect for growers that require a growing medium with good drainage, high air porosity and low water retention. The combination of fibrous Sphagnum peat moss and a high percentage of coarse perlite makes this formulation ideal for growers who require a growing medium product adapted to their needs for watering flexibility and crop seasonality. PRO-MIX® HP® contains a beneficial endomycorrhizal that improves plant growth.
Benefits

- Well suited for low-light and high-humidity growing conditions
- More difficult to overwater crops
- Reduces incidence of water-related problems (root diseases, algae and fungus gnats)
- Holds less water for improved leaching of fertilizer salts during crop cycles
- Supports plant root systems
- Enhances nutrient and water uptakeÂ
- Produces more vigorous and healthy plants
