I suppose that would all depend on wether or not your using LST/SOG methods. If so yes about 1 foot height would sound appropriate. Also, my own personal guesstimate on distance between pots would be around 6 inches. But then again that depends on how lush they grow. If they overlap leaves just a little thats fine but it shouldn't be too much. You want as much light penetration as possible. Hope this helps and happy growing.
