Pasteurized Manure Based Mushroom Substrate is specially formulated mu Review: Mushroom substrate and casing. - Hello, I just made another purchase using desertcart Prime and bought some Out-grow products. Quality and provides great results for my fruits. I usually make my purchases from Out-gross website but I decided to go the desertcart Prime route this time around. 4 bags of mushroom substrate and 5 bags of casing. (Sterilized) In the past have have just purchased their 50/50 wheat straw and bulk. I never had the need for a casing. I am confident with their product but I asked for my items to be placed in one box. Each bag is clearly labeled casing and substrate. I'm just a bit confused with the product inside each bag. The casing has what looks to be some wheat straw, bark or mulch and has an ash and leathery like smell. Confused with the bulk bags too. It has a fresh smell and light brown color compared to the casing. Light and fluffy almost like Coco Coir and horse manure (hopefully) appearance but could be pest moss. I'm not sure... Like I mentioned the bags are clearly labeled but the casing to me looks like it could be the bulk and the bulk could be the casing. I hope I am wrong but I am sure to find out soon because casing that I just purchased and applied will hopefully be happy and sprout some tomatoes soon. Like I stated before I usually purchase from your Out-grow website. I personally like your 50/50 sterilized bulk, your Coco Coir, also your 1\2 gallon horse manure and have had amazing fruits and flowers. Review: Good Sh!t !! Literally! 'Dung loving' mushroom cultivators , look no furthur!! - Was a little pricey with shipping cost, but I would say that despite the cost the quality of substrate I received was worth every penny of what I paid for. I mixed 2lbs of colonized grain spawn with 2 Lbs of substrate (1:1 ratio) in a mono-tub setup and within 10 days the substrate was fully colonized.. It went on to produce 5 flushes of beautiful mushrooms that were magically delicious 🍄🤤 ## Features - Easily grow your own mushrooms in bulk - 100% premium mushroom growing substrate - Fully pasteurized and ready to use - Water content guaranteed and ph balanced - Works perfectly with fully colonized spawn ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003N07MYG | | Brand | Out-Grow | | Brand Name | Out-Grow | | Customer Reviews | 4.1 out of 5 stars 656 Reviews | | Global Trade Identification Number | 00689466311730 | | Item Type Name | Toy | | Item Weight | 1 Pounds | | Item weight | 1 Pounds | | Manufacturer | Out-Grow® | | Manufacturer Part Number | ZOE-PN-95688391 | | Model Number | ZOE-PN-95688391 | | Style | Modern | | Style Name | Modern | | UPC | 689466311730 | | Unit Count | 1 Count | | Unit count | 1 Count | ## Product Details - **Brand:** Out-Grow - **Global Trade Identification Number:** 00689466311730 - **Item Weight:** 1 Pounds - **Style:** Modern - **UPC:** 689466311730 ## Images ![Out-Grow Manure Based Mushroom Substrate in Mushroom Grow Bags - Image 1](https://m.media-amazon.com/images/I/7155wE784SL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Mushroom substrate and casing. *by T***R on 4 May 2017* Hello, I just made another purchase using Amazon Prime and bought some Out-grow products.

I have had contam issues with other brands. I have good results with this. I wish i could give 4.5 stars but going with 4. The reason for the not perfect rating is the sub was just slightly too wet. Not bad and it worked fine but felt that is about two steps past field capacity. ## Frequently Bought Together - Pasteurized Manure Based Mushroom Substrate in Mushroom Grow Bag - Sterilized Rye Berry Mushroom Substrate with Self Healing Injection Port (1) - BRF Jars Brown Rice Flour Mushroom Substrate --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/278165918-out-grow-manure-based-mushroom-substrate-in-mushroom-grow-bags](https://www.desertcart.us/products/278165918-out-grow-manure-based-mushroom-substrate-in-mushroom-grow-bags) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
