Shipping in Overnight 50 degree temps (heat pack?)

[GregOyeah]

Hey all, I’m gonna be shipping on a day where overnight temps in Memphis and at the destination are gonna be in the 50s.

My first instinct is that I should put a heat pack in but I also don’t want to over heat the box. Any experienced shippers have any thoughts?

my experience and practice is:
heat pack ONLY if temps are approaching freezing
ice pack if the temps are 90 or above
neither one if the temps are between these.

I had a guy ship me corals this July who decided itd be a great idea to put a heat pack in the box. At least he said they were corals. They didnt look like it by the time they got to me :/

Too cold is safer than too hot, unless the cold is near freezing.
