I have the pro 200. It has 24 hour timer, pump(which suck) and 3 lights. I run a 175watt metal halide lamp. Honestly. I dont use the pump anymore, I use airstones. Im only using the aerogrow light to just get more light to the lower shelve, its sitting on the ground. I run a seperate timer for my lights, have the aerogrow plugged in to so its lights turn off at the same time and another CFL light on the other side. I run the airpumps pretty much all day(dont know if its good or bad)
so keep that in mind before you buy one! I could have made a better set up for the same price!
