Cycle timer can be found online anywhere from 40-80 bucks. Also people sell modified ones on eBay that work nicely, I recommend something you can adjust, you will likely find yourself wanting to play with the sprayer schedule, nice to not have to make a purchase everytime.
As far as I know everything for stink is the same besides the ball valves and such to be able to shut off each sprayer line to be able to drain res quicker. I suggest checking out superstoners threads if you are interested in adjustments/modifications/improvements to this system, his nutrient recipe has been tried and proven, one of the big improvements being the addition of bennies, or a "live rez" i started without having any defense to algae or slime (sterile or bennies) just ro water and nutes and I got hit quick and hard. all the information can be rounded up between his two threads.
For what it matters I am running bontanicare, the kind line to be exact, mainly because I am running RO and thought the added ca would be beneficial. (Stink was running them at one point)
