PRO-MIX® BRK20 is a peat-bark based growing medium similar to PRO-MIX® BRK, however bark content has been reduced to 20% by volume. The result is a general use growing medium that holds more water than PRO-MIX® BRK and has a lower bulk density. This medium has been enriched with a biofungicide (Bacillus Subtilis) that prevents root diseases. These bacteria colonize developing root systems, and suppress disease-causing organisms, such as Pythium, Fusarium and Rhizoctonia, which attack root systems. The bacteria also act as a biostimulant developing with the growing root system. A vigorous root system is then established, resulting in more uniform plant stands after transplanting in the field and in greater crop yields.
- Peat bark-based growing media for transplanting a wide variety of plant species
- For large cell-pack bedding trays (i.e. 606 and larger), pots and containers up to 2 gallons
- Contains bark for high porosity and improved bulk density
- Has the lowest water retention and highest bulk density of all PRO-MIX products
- Contains BIOFUNGICIDE™ (Bacillus Subtilis-MBI600)
- Reduces overwatering risk
- Increased drainage
- High bulk density ensures good pot stability
- Growers can use fertilizer regimes similar to peat-based mixes, unlike other bark-based mixes
- BIOFUNGICIDE™ reduces incidence of root diseases to improve overall growth of plants
