The Ballast for that light should be part of the bulb itself so no you do not need a ballast. How is the water going to be given to the plants? on a drip stake or?? The reason why I ask is you have to remember that Rockwool holds water VERY well so your water time might be a little to much but you prob wont know for sure until it is up and running. The CFL's will prob work ok for Vegging but when it comes to Flowering you cant beat the difference a true HPS light will do for you. Lastly take your time installing the Mylar, can be a little hard to work with. Be carefull about wrinkles and such as hot spots can be created. 2 sided poly (white/black) is allot easier to work with. Is normally thicker (4 mil) and allot more forgiving when trying to clean and maintain. As for Nutes I have been using General Hydroponics nutes with very good luck. I only use the FloraMicro and FloraBloom and get plenty of N/P/K that is needed. I also use a decent size airstone in my res to keep the O2 up in the res.
