Gypsum Powder - Elevate Your Mushroom Cultivation with High-Quality, Solution Grade Gypsum
Vital for Mushroom Cultivation: Gypsum powder is essential for creating the ideal substrate in mushroom cultivation due to its roles in pH adjustment, calcium supplementation, water retention, and improved oxygen circulation and mycelium growth.
Supports Healthy Development: Our premium-grade gypsum powder ensures the necessary pH balance and provides vital nutrients (calcium and sulfur) for mushrooms to thrive.
Improves Moisture Retention: Gypsum’s unique properties allow it to absorb and retain water, helping to maintain optimal moisture levels in the substrate.
Prevents Clumping: Adding gypsum to the substrate prevents clumping, enhancing the texture and promoting air circulation, which is crucial for preventing harmful bacteria and fungi growth.
High-Quality Gypsum for Soil Improvement: This high-purity gypsum serves as an excellent soil amendment, improving soil structure, reducing erosion, and supplying essential nutrients like calcium and sulfur to both plants and mushrooms. Contains 97% calcium sulfate dihydrate.

Until I have an issue I can only say that the quality and consistency in their products is why I recommend once past the beginner learning phase.

This company excels at packing their products. Living in Hawaii, where items often shift during transport, I appreciate how well they package their grain and substrate. I never have issues, so I'll be purchasing all my grain and substrate from Mycology Simplified. I love the stickers.

I wanted to try something new other than BR and drippy 🌽. I was shocked to see the mycelium growth after a few days I was expecting at least a week. I really love the packaging as it came in double sealed perfectly. Super sterilize and I didn't have to worry about buying a pressure cooker

I love the black contrast I'm able to see growth a lot sooner than squinting. Also is way more shelf stable in my AZ heat than a nutritional yeast I had purchased

Super reactive to the mycelium! I will be getting more soon. Company is fast to ship great quality products

So much better than this roll of parafilm I had bought that turned out to be just Saran wrap. I had dropped a plate and the wrapp unraveled. This is secure and I I feel like it better against contamination

Inoculated two days ago and I'm already seeing mycelium growth 📈. I will be purchasing again soon. I love the stickers that came with it. I made two separate purchases and got different stickers which made me happy.

The mycelium taking off like crazy! It loves this stuff.
