Review: Very tasty - It took a little while to start working but I have generated two harvest so far. So tasty when fryed with some olive oil and soy sauce. I see the start of a third harvest growing but it does take awhile after harvesting to see new growth.
Review: Nothing grew……(REVIEW UPDATED!!) - Review Update below original review: So I received my kit on October 24 and read the instructions and started it the same day. So far I’ve done everything that it said to do and absolutely nothing has happened and today is November 5th. I’m so disappoint because I was so excited to grow my own mushrooms. I haven’t given up yet and will continue to do what I’ve been doing but so far I’m very disappointed 😞 Ok so after weeks of spraying the thing for weeks and nothing happening I took it upon myself to put water in the bottom of a container and sat the block in box on top of a bowl so it wouldn’t get wet. I made a humidity tent over the whole thing and misted the inside of the plastic at least twice a day and lo and behold after a week or 2 it started to grow!!!! I’ve never been so excited about a fungus in all my life!! lol I feel like this idea should maybe be written in their instructions as a trouble shooting kinda thing if you’re not getting any growth!! But anyway I’m thrilled to see them growing finally!!!

## Questions & Answers

**Q: When should the mushrooms be harvested?**
A: The image on the front of your Spray & Grow Kit box shows the mushrooms at their ideal stage of growth for harvesting. The general rule is that mushrooms should be harvested before their caps flatten or become concave. In the case of lion's mane, before they become yellowed and mushy.

**Q: north spore, please answer, why aren't you accepting snap for payment?? the usda stipulates that all food plants and seeds to grow food are eligible!!**
A: I guess depends on the seller if participate in accepting snap or not.

**Q: Should it be put under a Heat lamp?**
A: Nope, definitely not. These like it on the cooler side and prefer a higher humidity.

**Q: Is this mushroom kit EBT eligible?**
A: Depends on the seller.
