if i run 2x 600 watts in a grow lab 145L tent??

will those lights plus fans and everything else be too much to plug into wall outlets with nothing done to them??will i blow a circuit with this amount of electricity being used??

each of your items should have an amp rating. look in your power box, find the correct circuit. it will say how many amps you can run. most likely 15 or 20... add the amps up of your appliances. its good to have a couple amps under the maximum. hope this helps
