Perfect substrate mixture if your tight on space. ### ⭐⭐⭐⭐⭐ Made growing easy! *by D***N on November 26, 2025* Worked great. Way easier than making my own substrate. I grew some Oyster mushrooms just so I could learn how mushrooms grow and a little about Mycology. This is a lot of substrate and went a long way. ### ⭐⭐⭐⭐⭐ Great product but use less than recommended *by J***J on November 9, 2025* I’ve used this twice, both soil were sterilized and both created a full flush. I’d purchase again however I recommend using more inoculated grain and less soil when layering. The soil can easily suffocate the grain, making it grow slower and/or causes it to mold. ## Frequently Bought Together - Surfin' Spores Premium Bulk Mushroom Substrate - 20 lbs Expert Mycologist Blend of Coco Coir, Vermiculite & Gypsum, Pasteurized & Odor-Free, Long Shelf-Life, Ideal for Monotub Cultivation - Myco Labs Premium 5-Grain Mushroom Spawn Bags | Sterilized Grain Spawn | Injection Ports | 2 Quarts Each Bag | 2 Bags per Box --- ## 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.tn/products/629732077-surfin-spores-premium-mushroom-substrate-20-lbs-bulk-cvg-blend](https://www.desertcart.tn/products/629732077-surfin-spores-premium-mushroom-substrate-20-lbs-bulk-cvg-blend) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-13*
