I first measure the amount of cord I need to get to the first light, then I cut the cord across with scissors, then cut however much cord is between the first and second light. Strip a 1/2" of plastic off the ends, connect the wires and then put a wire nut on. Well.. I'm tired and so I'll just draw a picture. Remember that there is going to be 3 wires going into every nut except for the last light on the circuit. You can connect however many lights you want in a row as long as you don't exceed your 15amp circuit breaker. The oarnge is the extension cord, the oarnge dots are the wire nuts, the black is the black wire and the red is normally the white wire (sometimes you get 2 white wires, then just cut off the extension cord where you need it, strip it along with the light bulb, then plug in the cord and carefully touch the wires together while NOT TOUCHING ANY OF THE METAL. If it lights, it works, if it doesn't light, then it won't work, for ones that work both way, do it however you want)
I am trying to do a better wiring setup for this next grow. I want to do more of a professional, clean looking setup this time.
