I have a large upright deep freezer that I keep in an out building, I intentionally bought a non-frost free model so that it doesn't periodically "warm" for the defrost feature. Summers here get above 100F and the humidity in eastern Okla. (
Green Country), is usually high in the Spring, Summer and Fall. I keep the freezer set -well- below -0F and have had no problems for the past
three years. Once a year I move my liquid Nic over to my regular freezer and defrost the deep freeze, moving it all back when finished. My liquid nic is stored in 60ml opaque glass bottles which in turn are organized in stackable plastic containers, my "stash" (
currently 11 liters of 100mg), occupies less than half of one shelf. If you
buy a well made
well insulated freezer, keeping it in a hot environment doesn't make much of a difference
unless you're constantly opening it
throughout the day, then it might.
