I guess I am a cheapskate - I always try to establish my trades before I order any new ones
I bought a large jar of cinnamon for less than $2 at Aldi.
I poured about 1/4 of it into a gallon zip-lock with about 2 cups of vermiculite, threw in 4-8 tubers at a time and gently rolled them around (I am sure you remember "Shake & Bake") - after doing that 8-10 times I needed to add more cinnamon, but the jar lasted through all of my 400 plus tubers.
