well you dont need to use led lights you can use other lights that will do the same job, you could for example use flo. lights you can also use some light balbs, you want them bright but you can even get cfl lights, compact flu. light. do a ebay search so you can see pictures. you also need to look for spectrums in the lights, for veg you need 2700k and flower is 6500k
cfl lights are about 40 watts, so you will need some cords you can put the light bulbs in one end and the other plugs in, real cheap to set up. theres also lights you can use from street lights but i would nt recommend that with out getting caught but you could get 2 and have some good free lights, but for money you could buy horticulture lights that are cheap but you start moving up in cost, then your leds, ect. outside, free well hidden, and last resort you could put it in a window and add extra light for longer grows.
