One of my cocoa seeds is sprouting despite my failure to give it a secure 85°F+ incubation.

What is the success rate of unheated cacao/cocoa seeds and how long do they usually take to noticeably sprout?

Sheesh. My mangosteen was easier on my nerves!

Setup: large styrofoam cups with filtered bottom, moist wet soil.

I'm using a heating pad to give them a small temp boost during possible draft times.
