you dont have to be so anal about the temps and all the preciseness and stuff haha unless thats just how you are.
i just throw seeds in a damp paper towel, put em in a cup, put a bag over the cup and put it somewhere dark like a shoe box or cupboard.
check it every day after 24 hrs, when i see a taproot i throw it in rockwool and put em on top of my cable box for a little heat. ive had bad luck with heating mats being too hot and humidity domes havent seemed necessary. once it comes out of the medium and reaches for the sky i put it under light.. i always have success..
not saying thats the only way, just showing that you dont have to be so crazy about making everything perfect, you could really just put the seed in soil and it will pop up. its nature so dont sweat on it too much ya know.
i can already tell youre going to do a good job because youre so open to learning.. you will learn a lot here. i sure did. just dont get too caught up on specific ways, theres a million ways to do everything and everyone has their own way so just find yours and perfect it. and remember its a plant, it grows on its own really you just gotta help it.
