At Major Mushrooms, we believe growing mushrooms should be both practical and inspiring. Whether you’re running a farm, a small lab, or a grow shelf at home, our cultivation supplies are the same clean, consistent materials we rely on in our own production facility. Every batch is prepared, sterilized, and sealed on-farm under the same standards we use for our commercial grows — because dependable inputs are the backbone of dependable results. All sterile products are guaranteed clean when they leave our facility. If something gets past our quality control, we'll replace it, simple.
