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!!!

Bad Batch
Has a very foul smell and a lot of gnats…when I googled if this was normal, Google said no…I’ve only had it 3 days…followed the instructions… I’m very disappointed…I was so excited about growing my own mushrooms…I will not be buying from this company again…I also read this isn’t how it was supposed to look…The MFG Date says 7/03….I received the Kit September 21th, Today is the 24th…it’s almost 3 months old, this can’t be right!

Mushrooms are great!
Just harvested this morning, can’t wait to eat for dinner. Three weeks to this first flush. These were really fun. I did water more than 2x\day…more like 4x.

Fungus gnats
When the company Ì had been buying my blocks from went out of business Ì decided to try North Spore. I immediately put the block in my smart box grow unit. By the 3rd day I noticed fungus gnats!! So disappointing. I put a small dish of vinegar solution in the unit and it does look like the block may pin but we’ll see. Update; black mold developed and block tossed. Would not order again.
