Reishi is a mushroom with mystique, history and healing reputation. If you have dreamed of growing something ancient, functional, and beautiful, our Reishi Grain Spawn Bag lets you do just that. The spawn is pre-colonised, using our high-yield G1 culture strain, so as soon as it arrives you are ready to go. No need to wait for spores; you jump straight into fruiting block preparation.
Reishi is a tough, woody mushroom, not one for eating in large volumes, but its presence is powerful: great for teas, tinctures or just as a majestic fungal fruiting in your grow space. Because of its nature, growth is slower than your oyster mushrooms, but you will be rewarded with good, dense growths and large cap structures. For yield expectations, once the substrate is mixed and conditions are right, you can begin harvesting about three weeks after spawning.
This spawn is compatible with different substrate types — hardwood, sawdust, or mixes — and works well in monotubs or block style fruiting environments. Reishi prefers stable warmth, high humidity, and lower fresh air exchange until fruiting starts, then more air helps form the fruiting bodies. Lighting should be indirect but good.
Overall, this grain spawn bag gives you the chance to grow Reishi with much less fuss. It is perfect for growers who enjoy a slower pace, patience in cultivation, and getting returns over time. Whether for wellness or pure fascination, Reishi rewards the grower who takes their time.
