Thanks CPW, yea i want to make one like that, my $40 dlr wifi/smart toy is not really working how i want too. It clogges very easily and some plants get water and other dont, hell ineven got water all over since it ran over and spill all the outside floor cuz it eas feeding only 1 plant and all the water went to her. So yea ingot everything pretty much to make a diy one, wavemaker, airstone, 20g res, and tubing. Just need a good recommendation on the type of pump and that manifold u mention what is that? (excuse my spelling i hate auto spelling)
