Supplemented Hardwood Substrate - 1 Bag Per Order - for Wood Loving Mushrooms - Hardwood Sawdust (Oak) Mixed with Bran - Use to Grow Gourmet Mushrooms - Ready to Use

I greatly appreciate the caution label! I knew right there, that they take pride and great care of their products! As I took out the substrate from its package, I noticed it was very well sealed and exactly what I was wanting!!! I am very pleased with this product and I will be making another purchase soon! Thank you!!!!!

I ordered 7 of these bags. They are not sterile. In fact I have Trichoderma and white mold growing on themDon’t waste your time and moneyDry not moist. Loose crap

I will buy again. One was busted in shipping. They replaced it free. These bags work well. Great product!

Wood was damp on arrival, while the bag had a vent (to try and keep moisture down I guess) it did not work well. There was mold growing in it when I first opened. I ended up leaving it out in the sun for a few days to dry out.

The product came contaminated with mold (Trichoderma by my estimation). Product is not sterilized properly and not safe to grow mushrooms in.

Moisture is at field capacity colonization and fruiting was faster than I could have hoped for or keep up with honestly

Silly me didn't read reviews. Came in wet and moldy. Sent back.

Bag started growing mold. Refund process started. Will not be using this vendor again. This could have destroyed an entire lab of the contamination got out.
