browse thru the grow room set up area .It sounds like your testing everything in your room first thats good. Electricity is a bit of a pain I currently have double 15 minis on almost all my breakers mainly double 20's now lol. But yeah growing with the elctrical know hows tough and do it yourself is dangerous. Find a buddy whos a elctrician and swap out those breakers. Im not looking to see what your set up is but always gonna have to control heat and humidity , the problem with that is humidity control means dehumidifiers that make heat. Good luck
