bro i could give you a lot better advice on the mechanical side, theres some bad ass gardeners on this site that you could read there grows, im a few weeks into flower of my first aero , all i can tell you is its unbelievably fast, i tried to veg 6 in a similar system for 4 weeks and had to pull 3, i still had to do a lot of trimming, unless you tie em up those small cups can fall over, if you veg for 2 weeks there going to be pretty big by the time they stretch. make sure you drill the holes a little small so the cups are very snug. im going with 3 or 4, 4" cups next time with a 2 week veg, im using a 1k hps and co2 and it grows so fast its like learning how to drive in a dragster, the most important thing i think is res temp, no mater what you have to keep your res below 70 and its tuff to do without a chiller unless you want to babysit your res with frozen bottles, i bought a cheap one on e bay and they are very simple to hook up. sorry i cant give you a better answer to your question
