Personally, as a formulator for a lifetime, I am partial to having visual contact, arms reach, multiple shelves and levels for my essential oils, tinctures, powders, skunk and Civet essence, crystals and gums etc. I know I am leaving a few things out. But you get the idea.
Essentially most all active ingredients including castor, both powder and paste types are all keep in a 15-foot range. I like to have them all at my beckon reach as I need them. Measuring materials, blenders and scales everywhere. I know where everything is due to muscle memory. However, when that goes bad, I am in trouble.
When I am working up batches of product it sure makes for an efficient operation. No talking, no visitors or phone calls.
The middle and opposite end of the shop is for processed glands, aging meats and bases.
Reading labels on a packer daily as needed to find or to locate something would be a big issue for me. Then what you need is always in the bottom packer etc. I don't see you working in that fruit cellar or outhouse for long. We will see...............
