Overall rating: 4.9 / 5 from 28 reviews.
I like this stuff… second order was a slightly different mix, less crushed oyster shells. I preferred the first batch.
Also have a seedling growing in the second order. Not sure how a seed makes it past pasteurization. ?
Delivery is fast

First time doing a monotub and i started with 66qt. Mixed a 1lb bag of horse manure booster from Midwest, 10lbs of premium substrate from Microppose and 5 lb bag of colonized grain. After 4 days the whole tub is almost fully colonized. I recommend this top quality substrate.
