Why not just go with Waterfarms. The advantage is you can move the buckets around and place them as space/light dictates. I almost went with one of those stationary drip systems but am glad I didn't for my needs/lifestyle....with individual buckets you can move them around as needed which makes the more flexible/adabtible to different grow rooms (when you move, etc).

With the Waterfarms you can easily get 3+ oz per healthy Indica plant

You can get a complete 8 bucket system for ~299 or you can just buy a few individual Waterfarms and their resevoir for much cheaper if only doing a few plants. Many good options out there, but almost every hydro store sells Waterfarms which makes replacement parts (if ever needed) easy to get. Only mods they need is to drill ~10 extra 1/4" holes in the bottom of the baskets to allow for more root penetration, and maybe have the buckets recirculate if doing more than 4 buckets, other than that they are trouble-free and low maintainance. Best of luck on whatever u decide and enjoy!
