So i have a bag of perlite, hanging out in my incubator, waiting for my girl to ovulate. this is my first year breeding (and hopefully it will be my first year with eggs too!!) and i was wondering. i read that alot of people use a mixture of perlite and vermiculite. I've also read about just using hatchrite, or just perlite. ive read bad things about using just perlite. my question is, what would you do?
