Yes, kick ass screen marv. Cute kitty too. So i wanted to strongly suggest that if you havent already, superglue that little brown plastic piece to its tube, on your waterfarm. The one that the air line is attached to... Because if (when) you get a clog in the air line, and your nutes stop coming out of your ring, you'll have to thread that whole tube part out, so you can cut the clogged part of your air tube off and re-attach it. And if you dont superglue that little brown piece onto your white downtube, it will come off when you try to pull it all out, and you will have to somehow get it out of your res... which is CRAZY hard and frustrating, IF you can even do it because of the screen. This may not make sense, but its a fairly common (and easy) "mod" for the waterfarms. I might also suggest, that if you dont already have an air line and air stone in your res (like a DWC) that you add one while you still can. For one, it will give your plants more air that they will love. And for two, if shit gets too bitchy with your drip ring, you've still got the bottom half running as a DWC as a safety net.
Just more of my 2cents. But i really wish someone would have suggested that to me before i ran my waterfarm-scrog.
