Usage
For In-Bag Fruiting
Add fully colonized grain spawn directly into the bag using clean hands or tools in a sanitary environment. Mix thoroughly to distribute the spawn evenly throughout the substrate, then reseal the bag. Once fully colonized, cut slits or open the top of the bag to initiate fruiting.
For Monotub Use
Use a ratio of 1 bag of grain spawn to 2 bags of RMS CVG Mix. Open all bags in clean conditions, combine in your monotub, and mix well to ensure even distribution. Flatten the surface and proceed with your standard fruiting process.
Storage Recommendations
Store unopened bags in a cool, dry place, away from direct sunlight. Use promptly for best results and to maintain substrate quality.
