(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

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.

Worked great. Grew beautiful mushrooms. I hadn’t eaten Lions Mane mushroom before so I wanted to try it. I love mushrooms but not this one. Otherwise I grew them within a week and cooked them and we ate them. I’ll have to try some I’m familiar with next time.

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.

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

IT WORKED.

I started using it the moment I received it. Ive used similar kits from other brands in the past with a lot of success. This one never even started to grow. I followed the instructions exactly and it just got slimy and weird. I reached out to the company but they didnt seem to care and said to wait a few weeks. I also noticed the kit I received was manufactured in 2019. Seems obvious why it never started to grow. I would not recommend buying from this company again or this kit.

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.

Ok so first off. I was missing the squirt bottle. No dig deal. I had some laying around. Second the brick came in a few pieces. Not the biggest deal. Understand that transit might of been a factor. But I feel the mycelium was rather weak from what I have seen before which would make breakage easier. So now the grow. I tried the way on the box. I live hawaii. Good humidity. But did it as instructed. For 3 days. Nothing happen. The block looked more and more dry. So of course there was something going wrong. But I grow mushrooms myself and I have a automated fruiting chamber. I put it in there and within 3 days. The mycelium was thriving and it looked so good. 2 days later it finally pinned. And now I'm almost a week in and it's definitely growing. I ended up taking completely out the bag. Took the broken pieces and spawned them to new substrate that I made. And will see how that goes but I can't hate it's definitely growing. But if I was someone who had little to no knowledge then it could of failed or maybe I didn't wait as long. But seriously the mycelium looked like it was dieing.
