How much should I spray my mushroom kit?

You don’t need to empty the bottle each time you spray, but it is important to get the area where you cut open the bag nice and damp! Try 5-10 sprays each time. It can take a little trial and error to get the frequency and amount just right. If the surface of the block seems very dry the next time you spray it, you should give it a bit more water or water a bit more often. If you run AC or live in an arid climate, using a humidity tent can be useful to prevent your block from drying out.
