Look for the head piece of the shed and see if you can find the eye caps. With eye caps on the eyes will look a bit silvery I think. Not sure. But ya just check through the shed skin pieces and see if you can find the eye caps.

As for which humidity meter to go with, Acurite all the way. It's the more accurate one. I think the stick on is reading higher because you have it placed up higher in the tank, where the humidity rises and escapes, and they're not too accurate, lol. So just go by the acurite digital. It's more accurate and it'll be a better reading since its on the ground where your bp is. Doesn't matter what the humidity is up high in the tank. Your bp will be on the ground right?

Congrats on the shed, and good luck on the humidity and temperature stuff.
