# How to Build a Four Light Grow

Anybody that has more than two 1000 watt Multiple grow lights in their home has likely keep running into the issue of how to supply power and turn them on and off. A standard 120 volt circuit in your home has a 15 amp rating, that implies one light. Note: I will utilize the expression “120 volt” and “240 volt” to depict the two unique sorts of circuits we will work with simply because that is the term the weight fabricates utilize. They are frequently alluded to as “110 volt” or “220 volt”, really on the off chance that you gauged the voltage with a precise meter a 120 volt circuit regularly will be not as much as that a can shift. A 1000 watt light draws around 9.2 amps at 120 volts (1100 watts/120 volts = 9.17 amps). See this page for other balance wattages. On a 240 volt circuit the amperage is 4.6 amps (1100 watts/240 volts = 4.58 amps), so when running different light frameworks, it’s less demanding to wire them for 240 on the grounds that you can utilize littler wire.

In a 120 volt circuit, the power lines have three wires; a dark, a white and a green. The dark is the “power” or 120 volts, the white is the “normal” or “return” and the green is the ground. In a three wire 240 volt circuit, similar to we use for Multiple grow lights, there is likewise a dark, white and green. The high contrast are both 120 volts (180 degrees out of stage with each other) and the green is the normal and ground. In a 240 circuit we are part the heap between two wires.

The issue for the greater part of you is that you can’t go out and purchase a clock that you can “connect to” four lights. I have taken a gander at a wide range of lighting controllers for the hydroponics business and found that most are \$200 to \$300 for what sums to a \$30 transfer in a case with a few outlets. I know a considerable lot of you get a kick out of the chance to manufacture this stuff all alone, so I setout to construct one of these in view of security and low cost and to get as quite a bit of it from Home Depot as I could. I realize that some of you have constructed controllers in light of the Intermatic T103 clocks like this one, they will work for four lights yet what do you do when you have eight or twelve lights and you need them to turn on in the meantime? The appropriate response is a transfer.

A hand-off works like a light switch, it associates and detaches two wires. The distinction is that as opposed to flipping the switch with your finger, a transfer has a loop that when power is connected, it makes the association. The benefit of this is the loop requires just negligible current. The one I am utilizing draws 85 milliamps. That implies I can control many of these transfers with one 15 amp clock. 15 amps/.085 (85 milliamps) = 176, or 176 four Multiple grow lights controllers. I don’t know whether anybody has 704, 1000 watt lights, however in the event that you did you could turn them all on with a \$10 Home Depot clock! One issue however, regardless you require 176 diverse 30 amp circuits….. On with the venture.
