Organic Masters Mix – Ready-to-Use Pasteurised Fruiting Substrate

The number one cause of contamination is leaving bags in the original packaging for too long. Remove all sterile grain and substrate from the packaging when it arrives. Allow air to reach the white filters.

Before you get to work, have a quick check of all bags to ensure no splits or damage has occurred during transit. If you find any damages or issues

Store grain and substrate in a cool dry place (not the fridge). Use by date on the bag although the highest chance of success comes from using the product at it's freshest.
