Grain Spawn from Martian Mushrooms I ordered grain spawn from Martian Mushrooms and I’m really impressed. The shipment arrived quickly, the packaging was clean and professional. The grains were perfectly hydrated and colonized beautifully and evenly after inoculation – see the attached photos. The quality is obvious at first glance – no contamination, strong and healthy white mycelium, and vigorous growth. I highly recommend Martian Mushrooms to anyone looking for a reliable source of high-quality grain spawn. I’m now preparing my second order – this time I’ll be trying their liquid culture, and I’m excited to see the results.
