Still Air Box

A still air box is basically just an upside-down large clear tupperware container with two arm holes cut in it. The idea is that if you clean the box really well, set it up, put all your stuff in it, and then just let it sit, that the majority of bacteria that’s floating around the air inside the box will settle to the floor of the box. Then, when you stick your arms in the box to work, you’re working in slightly cleaner air than you would be outside of the box.

Look up some YouTube tutorials on how to build a box and how to use it. The mycology community is your friend with this one.

Do not build a box that has gloves taped to the inside of it. While at first it seems like this would keep the box from being exposed to new air when you insert your arms, the reality is that because the box isn’t sterile on the inside to begin with, that the gloves end up facilitating a bunch of air currents inside the box, and stirring around a lot more bacteria than it would otherwise.

The still air box can be used for the small guide (optional) or the medium guide (required). It cannot be used for the large guide.
