mush-O-sphere - THE HUMIDITY TENT
This is how the humidity tent slips on. Use the Velcro tabs to secure it - It doesn't need to be tight or aligned perfectly just as long as it holds.
As the mushrooms start to form most varieties will do better with more fresh air. The green-colored velcro tabs on the side and top can be connected to allow more air when the time is right.
you may decide to open up the humidity tent really wide like this towards the end of the fruiting cycle. Sometimes paper clips can be used to help the tent stay secure and dial in a good fresh air/humidity balance.
The humidity tent is designed to be able to slide on/off during a grow cycle at any time, even as the kit hangs. You may wish to remove it entirely if you are in a humid environment or if the mush is almost fully grown.
