1 a still air box, arm holes cut for you, let's be real. Sab's are best for those with low budget. But maybe you don't want to spend $60 on a circle saw, spend time sanding (on the other hand of that, getting your arms sliced up by sharp plastic) or risk toxic fumes with a metal tin and your stove.
I'll do it for you. Glove boxes or "sabs with built-in gloves" are not what you need if you're looking for a place to perform sterile work. 2 one 4oz glass jar of sterilized spawn that is ready for innoculation.
3 four of the same 4oz glass jars - partially filled with agar - ready for innoculation/germination. 4 one surprise mushroom sticker.
