thinking also about adding in a drip ring for each tier, and running a clean ph'd res, with added h202

any input?? I eventually will get into brewing, I plan on my compost pile being fully ready in a year and I will start a wormbin for vermicompost and also get a brewer and do some ewc's too.
as for now I have nutes I would love to use up so i figured lettuce is something I'd eat up and would love the cold window during the winter.
the biggest problem I think with the drip ring idea would be flow rate. the top tier would have to have say, 6 holes, then the next have 5, the next 4 , and the last have 3.
the reason being, i dont think that the flow rate of the air pump will fill the rings and actually drip out of all of them for each one. if each one has a slower flow rate than the one before it i think it might help distribute everything more evenly, I'd just have to add in a screen at the bottom so i could avoid clogging
the beauty of an airlift though, is there is no clogging because the water never goes through any type of propeller.. I just am not sure if a single drip line will be enough to water these and think it might be better if i made something that would evenly disperse it.
any input on this?? I don't have a lot of exp. with hydroponics and would love any input on putting the 1x1 rockwools into the clay pebbles, and how i should Drip
remember though that each drip depends on the flow from the bottle above it :\
