Composted Pine Bark
Production of pine bark growing medium takes place through thermophylic composting. Fresh bark is milled into a specific size, urea and water is added and then this mixture is placed in long windrows. Temperatures are regularly monitored and when the heap reaches 70 deg C it is turned and aerated for the heat build-up to start again. This process repeats itself three times during a four month period.
A testing room on site allows us to monitor PH, EC, Sodium, Moisture and Temperature for our traceability reports. Once the product is stable with little variation in temperature, it is screened or blended and released to customers.
