I bought a back to the roots mushroom kit at Maker Faire last year, and despite following the instructions, it never worked. Turns out that just being close to the kitchen window, pretty much never in direct sunlight, was apparently enough to stop the mushrooms from coming out.
After getting a replacement, which didn't work either, I finally figured out that it really needed to be in a dark corner. The kit I threw away actually started producing in the garage without even being watered.
Once I figured that out, I was able to get the kits to work, first inside, and after getting the first crop, I put them outside in the yard for more output :)
Finally, got some mushrooms indoors, after weeks of failing :)
The other kit had other mushrooms, which were quite yummy too
Did we save money or time? Hell no :) but it's about the challenge :)
And I was able to get more by just putting the already used up kits outside
