Which end goes on top when I put the block back into the box after soaking? The light side or dark side?

Great question! As every block is different in the way the mushrooms colonize, I can’t say which side is lighter or darker. You can choose any side you wish to place back into the box as long as the X you cut in the block is exposed so it gets proper air exchange and moisture from misting! I hope this helps! Please don’t hesitate to reach out again if you have any other questions. :)

How do I start the second harvest? I see no exact instructions on that... Just the fact that it's still possible...?

Hey Jon! So if you take a look at the back of the instruction pamphlet, you're gonna see the section that says "Bonus Crop". In case you no longer have your instruction pamphlet, here are the instructions in simplest terms without images: We recommend if the mycelium around the original X incision seems to be dried and crusted, simply tape over it and flip your mycelium block and start over on the back side of your block. Then you will start from step 1 again, just like when you first got your kit. Cut an X, soak your substrate, and mist regularly. You should be able to get a couple more fruits in just make sure they get another round of soaking in! After their first fruit, they are probably pretty dried out. Hope that helped! :) If you have more questions please feel free to let us know.

Is it just one harvest?

No, you're able to get 1 or 2 more after the first one (but the first harvest is always the largest)
