Agricultural gypsum, also known as hydrated calcium sulfate (CaSO₄·2H₂O), is a natural additive widely used in the cultivation of mushrooms and edible fungi. This product contains an average of 22% calcium and 18% sulfur, minerals that are essential for the nutrition and development of mycelium.
In substrate preparation, gypsum serves a dual purpose: it provides nutrients that can be directly used by the mycelium and improves the physical properties of the substrate, promoting aeration and structure.
Main benefits:
- Calcium and sulfur supply: essential for the health and development of mycelium.
- Improved performance: promotes more vigorous growth and higher productivity.
- Optimizes substrate structure: promotes aeration and prevents compaction.
- Natural product: mineral-based and free of chemical additives.
This agricultural gypsum comes in 10 kg bags, ready to be added to substrate mixtures for the cultivation of species such as Pleurotus (oyster mushroom), Lentinula edodes (shiitake) and other lignicolous mushrooms.
An essential supplement for growers looking to improve the quality and yield of their crops.
