it is my favourite system, using growrock and a good control res, when done right, eliminates most if not all root related problems, as the plants are growing in air, I strongly recommend it, personally prefer it over DWC because it needs less equipment and tubing, no airstones less humidity less things that can go wrong, it is very easily automated with a simple timer, recycling is also very easy and is very clean unlike coco or soil.
In true aero doesn't it spray the roots with nute solution which then drains away to a res. Then sprayed again !---All I know is I copied that first aerocloner on a larger scale and the system works no matter what it's called and I'm O.K. with that !
That is the funny thing about grow methods. One method can work flawlessly for one person and fail miserably for another (in similar conditions). I think its because there are so many variables to contend with that someone who isn't highly experienced can easily forget to account for this myriad of variables that are present, and themselves vary depending on the grow method used.
I know that I have used similar methods under similar conditions and couldn't understand why they failed until I found the method that worked, and discovered that there were a few variables that I forgot to account for, which led to the failures, ie, cloning methods. :doh:
But spray valves are definitely bad for clogging up, even with the best of nutrients. The reason is often due to pressure causing changes in the solution which lead to minerals precipitating out of the solution and collecting around the sprayer valves. Pressure and temp changes can definitely affect the way solids dissolve in water, and stay dissolved or precipitate out.
the aero misters are known to get clogged often, and then you need a relatively powerful pump which means more power usage. When i chose ebb and flow, i wanted the roots to grow in air similar to aero, and growrocks provide this environment. It baffles me whenever i hear good growers say that it does not work for them, in my case, everything that i put in that system, be it weed or even veggies, grows great.
