This fast-growing strain of Shiitake is our favorite mushroom here on the farm. Once you activate your Shiitake mushroom grow kit, the first harvest will begin growing and will form big beautiful mushrooms over 10 to 14 days. Once the first crop has been harvested just soak the kit in cold water overnight and a new crop will begin growing in just another two weeks. Our Shiitake blocks produce 1-2 crops. Experience the joy and wonder of watching beautiful mushrooms grow before your eyes and then eating them!

The mushrooms are easily grown indoors at temperatures averaging 60-70ºF. They prefer indirect light and require a daily misting to maintain humidity. Our Shiitake mushroom grow kits are 100% Certified Organic blocks of enriched hardwood sawdust that is fully colonized by mycelium from our favorite hardy strain of Shiitake.

Each mushroom grow kit comes complete with care instructions and recipes!

I had this sent to my daughter for her birthday after my own great experience with it. She; was so happy and said it was the best birthday gift ever!

My daughter loves to grow things, is a great fan of mushrooms, especially shiitake and was thrilled with the successful and delicious results.

Fun and ea easy

First time growing mushrooms. Easy as can be. I'm almost always at work and could still find the time for watering. The results were very satisfying and I was able to make meals for myself and give some mushrooms away as presents to family and friends. Overall a fun experience that I'm excited to try again. Maybe even at the office! Thanks cascadia!
