Midwest's Select Bulk Casing Mix - 5 pounds

Pros:

effective
super fast service
great customer support

Cons:

Prior to my latest mycology grow efforts, I had only grown mushrooms sucessfully once almost ten years ago. I grew them directly in the grow bags which were from Midwest Grow Kits even then. After great sucess upon my maiden voyage to growing cakes in a fruiting chamber using Midwest's Mega Mushroom Grow Kit, I decided to evolve directly to a monotub project. I mixed two bags (10 lbs) of casing mix with two bags (5 lbs) of colonized spawn. I followed all recommendations, misting the walls of the tub daily, and literally watching the mycellium grow in front of my eyes. At day ten, I began exposure to the light. I expected pins within two to four weeks, but no. Two days, and not pins so much as a super fast and expansive flush that filled the fruiting chamber withing the first 5 days of light exposure. As a first time grower outside of bags, I haven't had experience with any other casing mix. What I can say is this. Midwest select casing mix is comparatively one of the lowest priced mixes. My experience with this stuff has been superior! I am super impressed with Midwest's Select Bulk Casing Mix. I am a complete novice who just reaped only his first flush, and realize I am short a few half gallon Mason Jars. I have already filled one jar. The results have been phenomenal

Love this stuff

This stuff is the bomb. Just mix mycelium, keep dark and moist. Mycelia took off like a rocket.
