We have perfected the art of substrate. We are proud to welcome some of the best rated substrate on the market. This sterilized CVG + worm castings blend of substrate is extremely user friendly and produces up to 3 flushes when used in our Monotubs. Simply mix one bag of substrate (10 LBS) with 4-5lbs of your colonized grain spawn and you will have your first flush in only a few weeks! Mushroom substrate or casing is moisture retaining medium to mix with grain spawn when growing in containers, trays, totes or "monotubs". This method is generally referred to as the "Bulk" method or "Monotub Method". This is the most popular way to fruit your spawn bags or whole grain jars. We provide easy to follow instructions on how to use and create your bulk grow. The hardest part of this process is achieving the perfect ratios of substrate, casing and water. We've made it easy! Perfect for grain or dung loving mushrooms! Use the following amounts: 10lbs per Monotub. 4-5 lbs of grain spawn per tub Shelf life of up to 6 months+ Show more
