Pro-Mix HP Biofungicide + Mycorrhizae is a high porosity peat-based growing medium.
With high perlite content, it provides significant drainage capacity, increased air porosity and lower water retention: it dries out more frequently than general purpose mixes and is perfect for low-light growing conditions and high humidity, reducing water related problems like root diseases, algae, and fungus gnats. An excellent medium for starting seeds and root plugs, this helps prevent damping off.

Pro-tip: This is boosted with Mycorrhizae but needs additional fertilizer to achieve maximum growth—but as a blank canvas for your amendments, it won’t contribute to fertilizer burn.
