Yep , Kyles right, No Sunlight.
Years ago, I worked at a feed store, and the owner integrated a health food store, with over 100, one gallon mayo jars, with bulk herbs on shelves on the walls.
The clientele, (that knew theyre stuff) got pretty upset, that the herbs were in clear jars , and taking in light, reflective light even.. They said the herbs lose theyre potency, and attributes.
So, you might want to find some sort of box , or cabinet, to store those jars in.
But, hey, thats a nice lookin setup you have there.
What kind of pipes are those?
And what baccys are ya smokin?
