Electircal set up.

Discussion in 'Growing Marijuana Indoors' started by hitmanbob, Jul 26, 2007.

  1. i'm a few days away from setting up my first grow, and im looking for a way to get electricity to where it is needed. i've got a standard, american wall outlet about 30 feet from where the electricity is needed. if i connected an extension cord, plug it into that, and then at the other end, plug a surge protector into the extension cord, will i have a problem with not having enough electricity? i'm planning on having about 200w of CFL lights, a small fan and thats about it

    the surge protector, on the back says

    "maximum load: 15A 125VAC 60Hz 1875W"

    im guessing that is 15 amps, 125 volts, 60 Hz(of what, i have no idea), and 1875 watts. Is this correct? and can a wall outlet put out that much? the room where the outlet only has a heater(for the whole house), 2 waterheaters, and thats about it. i am 90% sure it is on its own switch on the circuit board.
     
  2. You will be fine with that
     
  3. First off, I would highly recomend doing some research on elecrticity basics and learn as much as you can about residential wiring. This is always the safe thing to do, especially when dealing with electricity!

    Now your plug strip is rated at 1875W if you have at minimum of 125volts sitting at your outlet, which may or may not be the case. They get the 1875Watts from taking 125Volts and multiplying it by 15Amps. So, the formula is Power=Volts(Amps). Now depending on which values you have, the watts, amps or volts, you can always manipulate that formula to get the value you are looking for. So at maximum load, your plug strip can handle up to 15amps, which in my opinion is putting way too much continuous current through that thing.

    Without having to go through all kinds of crap explaining this all to you, I will tell you what will work without a dought. If you plan on setting up any kind of grow room at all, DO NOT run it with an extension cord. And if you do run it with an extension cord make damn sure that cord is at least 12AWG and I would upgrade that with 10AWG!! If you want to do it right and safe then I woould highly recomend running at least two more circuits to the grow room from your main panel in your house. Some people will say that is overkill for what you are going to have running, but from experience you will probably end up adding stuff that is necessary to your grow that requires more power than you have. For example, when it comes time to flower you will end up beiing dissapointed with the CFL's and have to go with an HID. Not only will you need power for your light, but power for your cooling system. Just add the extra circuits and be done with it. It is cheaper and easier this way in the long run.

    I have left a lot of important electricity facts out because I don't have the time to explain them to you. You NEED to know a lot more about electricity before you start rigging some stuff up so I would recomend on spending your next few days learning!!
     
  4. aight thanks. the extension cord i currently have is 10AWG.

    i currently don't have the option to wire another circuit. if i did i would definitely do it for the convenience, but this isn't a long term grow op. i'm living with my parents until about november when im going to europe for a few months. i might be able to hook up another cord in a different area of the house and run it under the house to the grow area.

    other than that, i dont think im going to need much electricity. i plan on having 4-8 plants under 200 to 400W of CFL. no need for MH or HPS currently
     
  5. \tElectrical Safety for the Indoor Growrooms[​IMG]One of the commonly asked questions regarding electrical and gardening with High Intensity Discharge (HiD) lighting is "how many 1000 watt lights can run on this set?" Generally an outlet on your bedroom or basement wall is part of a 15 amp circuit. There are up to 12 lights and or plugs on that circuit. A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit. A range outlet is typically 40 amps on an older house and 50 amps on a new house. Therefore you could run up to eight lights and 10 lights respectively. The important thing to check first is the breaker size for the circuit you want to use. The breaker is sized to protect the wire and then anything plugged into the circuit. Below is a table used to size wire for whatever load you have.
    \nYou must note that for safety, the Canadian Electrical Code states that you can only load circuits up to 80% of their recommended capability.
    Another common question is "Should I run my lights on 110 volts or 220 volts?" The answer is that it makes no difference - a 1000 watt ballast uses nine amps at 110 volts or 4.5 amps at 220 volts go on a typical dryer outlet. You can run six lights at 4.5 amps, 220 volts for a total of 27 amps, 220 volts or six lights at 9 amps 110 volts (three lights each side of the 220 volt circuit) for 27 amps at 110 volts and 27 amps on the other 110 volts.
