Hi Highdive, been following your grow and it is awesome!
About your circuit breaker popping, most likley it is a 15amp breaker. You can replace the breaker with a 20amp. or see if there is anything on the circuit that you can eliminate, that is not needed. Could also run another wire from the breaker pannel to the room creating another circuit just for your room. Please be very careful about overloading a circuits because of the obvious fire hazard. I also recomend changing the breaker that has popped, a breaker gets weaker if it is overloaded too many times.
I hope this can helps. Keep up the good work!
