I agree that the problems can be avoided or planned for, but they are a very real part of aero and pretending they don't exist is just begging to lose a crop and wind up regretting trying aero.
When my friend told me about the sprayer thing I was like that's a damned good idea, I can't I haven't seen it anywhere. The unit I'm building has 18 sprayers, 12 360° and 6 180°, so I need 3 extras to change everything every 6 days. That's $1.50 and all but garuntees that I will never have to deal with a clog. The fittings I'm using will never ever give me a problem. I've run gas at pressures exceeding 1,000psi through them. I wouldn't use them if I had to pay for them, but I don't need to so why not.
A good aero setup produces amazing results. They also are the most efficient in terms of water useage, so you waste less nutes. Having seen my friends results I would reccomend aero (I'm making the switch over now), as long as the drawbacks are taken into account and planned for.
