the lights as in the one connected to my light switch. The lights 'T5 and 1000watt HPS' I would have to plug into the recpticls. along with the rest of the stuff.
all my grow room stuff would be on one 20 amp breaker.
Monoxide, can you add up the amps drawn from all the components you have connected to the circuit. You should stay below the 20 amp breaker. If the amps are not shown on the device just divide your watts by voltage, that will give you your amps. So if your light is 1000 watts running off 120v you would have a 8.3 amp draw from your light. Somebody correct me if I am wrong.
