BRF Mushroom Substrate Jar – Half Pint

The Seismic Spore BRF mushroom substrate jar contains a perfectly hydrated mixture of freshly ground organic brown rice and vermiculite. Brown rice flour is rich with nutrients, while vermiculite retains moisture. Additionally, an extra top layer of vermiculite is added on top to offer protection from contaminants. Your mushroom substrate jars are sterilized and ready for inoculation upon arrival.

Our BRF jars are expertly designed to enhance the success of multi-spore syringe inoculations. The half-pint size of these jars is ideal for quick colonization. While the dense composition of the brown rice flour can be challenging, our Seismic Spore BRF jars address this with two Self-Healing Injection Ports (SHIPs), ensuring a more uniform spread of spores throughout the substrate.

Aligned with PF Tek Methodology

PF Tek was a revolutionary method in the world of mushroom cultivation, particularly popular among home growers. Developed by Robert McPherson, this technique has gained widespread acclaim for its simplicity and effectiveness, especially for beginners.

One of the key advantages of PF Tek is its contamination resistance, largely attributed to the natural protective properties of the vermiculite layer and the sterilization process. This makes it an ideal choice for spore syringe inoculation, as it reduces the risk of contamination.
