The one you are most familiar with, the one you have all dialed in. That takes time. So pick one, learn how it and your plants work together, and in a few grows, you may begin to see the potential of the perfect system. For you.
higher yields can be expected with a hydro systems, and if you want to be as efficient with your light youll want a vertical or stadium grow so no space/lumens are wasted. all depends what you can afford, i prefer outdoors.
