i never thought of that but i have my pumps and everything on the same outlet in a surge protector.

no extension cord

the pumps run all the time though

1 air pump
two water pumps
2 fans all the time / pretty small ones
fatatattat Reviewed by fatatattat on . 400w mh this is my first post and my first grow. anyway i got a used 400w mh when i started and maybe im just paranoid but it seems to me that it is putting out alot less heat and seems to be a bit dimmer and im wondering if it may be almost time for a new bulb. i have about 3 weeks left in veg and it is a very small space. im wondering since im planing on switching to an hps or a conversion bulb for flowering, if this is dimming on me a little will it be ok to stick with it till veg is done, Rating: 5
