North Spore Organic Lion's Mane Mushroom Spray & Grow Kit (4 lbs) | USDA-Certified Organic, Non-GMO, Beginner-Friendly & Easy to Use | Handmade in Maine, USA

This two-pack of 4-lb blocks is the best deal available for this species. The larger substrate holds enough nutrients to support a remarkable harvest, so the results justify the effort. Plan for proper temperature and humidity—around 70°F and 90% relative humidity—and choose the right season or indoor spot to maintain those conditions. Even as a beginner, I saw first flushes of over half a pound after trimming them to a market-ready appearance. The flavor is outstanding, and the mushrooms shine in sauces, sandwiches, or side dishes. Let the bags rest a couple of days before starting, and treat them like the living organisms they are. You’ll be glad you did.

Easy and quick to grow!

The kit provided two flushes of beautiful, puffy Lion's Mane mushrooms. I use the mushrooms to make Lions Mane tincture. I save a ton of money this way, and I know the quality of the product. I will certainly order again!

This is a great product you got to have a lot of patience

Grew on time still have about three days left. Hoping to see a second and third maybe even a fourth flush. Make sure it’s an almost constant 70 degrees maybe 15 degrees higher or lower at the max. In a cold dark room. Can’t wait to try it.

On the Lion's mane growing kit, I followed the directions exactly, got a little white to start showing, but then it turned into black mold, and never recovered or grew more. I kept spritzing it 2 twice a day for about 6 months when I finally gave up. I reached out to North Spore because they have a grow guarantee printed on the box. They responded to my request for a replacement with they won't honor the grow guarantee because I the grow guarantee is only honored for 3 months from the date of purchase. However I didn't see this catch written on on the box anywhere. Can't recommend this brand since it didn't fruit and became moldy, and they didn't honor their guarantee when I gave it additional time to grow and do something, to no avail.

This kit was exactly as described and worked perfectly- very easy to grow Lion’s Mane mushrooms. You literally spray twice a day with tap water… Follow the directions and you’ll get mushrooms to eat within 10-12 days. You can even reuse and continue growing mushrooms using the same kit after your first harvest. Highly recommend this!! I included pictures of the box throughout the 2 weeks it took to grow them.

amazon.com Feb 28, 2026 I received the lion's mane grow kit on Feb. 19 in good condition. I cut the plastic open in the usual X shape and put a hunidifier by the kit in the kitchen. It's now Feb. 28 and I just collected the large lion's mane off the grow kit. Very easy a nice looking fluffy mushroom! The size is about 8 inches high by by 6 inches wide and 5 inches thick. Pictures show day 3 and day 10, when harvested.
