Man, I would go with the Titan Flo-n-gro system instead. It has larger grow sites, larger diameter tubing, and comes with better pumps. It's the first system I ever used, and I've liked it from day one. The only thing I would change is making the buckets black instead of blue...
Honestly, I like it because it's almost idiot proof. My nutes stay at a pretty stable PH, and I've actually gone three or four days without having to actually adjust the PH... Just fill the rez and go. I'm thinking about setting up a top-feed system in the flower room to supplement the flooding. I've been reading that that will help tremendously..
