Aero systems are great, but require greater knowledge and have more ways to breakdown (more complex).

depends on how quick of a learner u are, i knew nothing about growing anything and within a 2 weeks time i had mine up and runnin. i mixed areo with dwc, so i have the best of both worlds. and mine is all made by hand, and that way if a pump does go out on one i still have the other. + the dwc allows more oxygen to the roots as well.
