My two cents is to start with a single plant, and grow it in a 5 gallon pot or bigger. Like others have said, don't waste money on a prefab system, instead get a good tent and build it yourself. I have graduated from a makeshift ghetto setup to a quality Gorilla Tent, 1000 watt LED and 4" fan and phresh filter combo over time (approx $1300-1500). If you are concerned about yields, sink your cash into more light. Light output equals more plants, more yield. Once again, you need to learn to start small like a single plant and grow through its full cycle. All you need is good soil (ocean forest or happy frog) and a bag of perlite to mix in maybe 30 percent. Then good genetics or seeds. Then a 5 gallon pot, light (I like at least 300 actual per plant) and patience....lots of that. Soil is way more forgiving of mistakes in feeding and condtions. Hope this helps, good luck.
