I'm planning on doing an extraction here in a couple weeks with around a pound of Mimosa, I read the Erowid tek here
Erowid Mimosa Tek
and feel I have it down for the most part I was wondering though, when I go to put my jars in the freezer do I keep a lid over them? or just have them open? I was gonna use some Mason jars or something. Thanks for any help!

It seems fairly simple. Easier than when I grew mushrooms so I shouldn't have too much trouble methinks, I'll just stick with the lids then
thank you endlessness
