Shroomability Gypsum Powder for Growing Mushrooms Food & Lab Grade for Mycology Purists (2 lb)
Main highlights- Overall, gypsum is a useful tool in mushroom cultivation and is often used in conjunction with other additives like lime, peat moss, and vermiculite to create a balanced and nutritious growing substrate for mushrooms.
- Our Gypsum is Food Grade not the much lower soil ammendment grade. We are Mycology Purists when it comes to ingredients. We use this in our mushroom substrates and you should too. We use this daily in our mushrooms substrate recipes and you should too.
- Gypsum is commonly used in mushroom cultivation as a source of calcium and sulfur, which are important nutrients for the growth and development of mushrooms. Here are some ways in which gypsum is used in for growing mushrooms.:
- 4. To increase mushroom yield: Research has shown that adding gypsum to the substrate can increase mushroom yield by up to 50%. This is because gypsum helps to create a more stable environment for mushroom growth and promotes the development of larger, more robust mushrooms.
- 3. To enhance mycelium growth: Gypsum contains calcium, which is an important nutrient for mycelium growth. Mycelium is the vegetative part of the mushroom that grows underground and absorbs nutrients from the substrate. Adding gypsum to the substrate can help to promote mycelium growth.
- 2. To improve water retention: Gypsum can also improve the water-holding capacity of the growing substrate. This can help to prevent the substrate from becoming too dry or too wet, which can be detrimental to mushroom growth.
- 1. To adjust the pH: Gypsum can be used to adjust the pH of the growing substrate. Mushrooms prefer a slightly acidic substrate with a pH between 6 and 7. Gypsum can help to raise the pH of the substrate if it is too acidic.
