I’ve had a little more growth on my cultivated Pearl mushrooms, but no mushroom heads, so I poked some holes into the substrate using bamboo skewers to let the water in. Now we wait. Again. I purchased this kit about eleven months ago. It produced about five small mushrooms, then I accidentally broke off the stems (they really do mean it when they say cut the heads off with a sharp knife, it needs to be seriously sharp to leave the stem cluster intact). No more fruiting bodies since then.
