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

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!

Easy and quick to grow!

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.

This product was easy to use and the first flush grew pretty quickly and easily. The second flush was small, discolored and kind of dry so I pulled it out and hoped for the next one...it never grew anymore mushrooms. I did soak the block as they recommended and put up a plastic tent around it but nothing else ever came of it. The first flush was very tasty and I was really excited to try more products from them...but for the cost it just didn't produce enough to buy it again.

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.

Packing is very nice and love that it comes with a spray bottle. Instructions were easy to follow. Sadly though it really didn’t grow for us. First round of one box had a little bit of growth (<1/2”) but it turned pink and brown that same day. I tried cutting it off and soaking for another round but nothing.

Amazing results!!! Follow the instructions, and harvest in several weeks!!!

Worked as advertised, nice healthy mycelium started fruiting in days. We did go ahead and put it in a clear tote and mist 2x daily. Never mist the mycelium block directly after fruits become visible.
