Pro-Mix HP Mycorrhizae Grow Bag

You can plant directly into the bag. It comes with pre-cut drainage holes and an easy-tear top, so it is designed to serve as both the container and the growing medium.

High-porosity means the mix contains a higher ratio of perlite, which creates more air pockets. This allows for better drainage and oxygen flow to the roots, making it ideal for plants that are sensitive to overwatering or root rot.

Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots. They extend the root system's reach, helping your plants absorb more water and nutrients, which generally leads to stronger growth and better stress resistance.

This mix is excellent for rooting cuttings and establishing young plants. However, because it is a high-porosity mix designed for drainage, you will need to monitor moisture levels closely if you are using it for very small, delicate seedlings that require consistent humidity.

While the bag is durable, the peat-based medium will break down and lose its optimal structure after one full growth cycle. For the best results and to avoid potential disease carryover, it is recommended to use fresh medium for each new crop.
