Yes, listen to the Bear.
You want one 20-a breaker per 1000w of usage that your growroom draws.
There is no greater nightmare for a grower than having to call in the fire department, who bring the cops with them... you know how that story ends.
stinkyattic Reviewed by stinkyattic on . Light question I'm running a 400 + 600 hps in my growroom fine on an extension cord then a contactor. I'm thinking of adding anothger 600 into the equation but fear it will be too much power from a single socket I cud use teh socket next to wall + have a seperate power supply for the extra 600. How much extra bud will I get with the extra 600 is 1 k of light enuff to get a decent yeild or do I need more Rating: 5
