if you are already on a 15 amp breaker
1 600 watt of flower
1 200 watts of veg
1 300 watts of fans and extra components for exhaust and ventilation

around 1100 watts of power
15 amp breaker is good for about 1800 watts and 80% of its power is good for about 1400 watts of power(dont want to exceed over 80% power much)

no electrition needed unless you want more hid lighting
texas grass Reviewed by texas grass on . having a electrician come out and wire everything to my room for all my lights,fans,,ect will be on a seperate breaker. I am going to have a veg box and a flower box. What Amps are you drawing with a big set up? Both my boxes will be 4 ft wide 6 ft tall 3 ft deep. I want to make sure the electrician goes overboard so there will be no chance of a fire or tripping the breaker all the time. Rating: 5
