Graphics devs, I have one hour a day i can spare for learning opengl and the math it needs to be understood. Is it possible or should i look for another hobby that is doable in that amount of time.

Definitely possible.

One hour per day over a bunch of days is a pretty long time, and your brain keeps processing it in the background anyway.

If you're starting off with OpenGL allow me to recommend this if you're familiar with C/C++ already: http://www.opengl-tutorial.org/#
