why do you want the super system?
I would opt for a basic system to control the temps alone.
use an appliance timer for the lights, and handle humidity on your own (I dont think helix can help you with humidity)
Unless you want to spend the extra 100 US to have your lights slowly dim down and up, then go with the supersystem.
Either way, Helix controls are the best!!
you wont regret the fact that you never have to worry about your temperatures again!
id spend the extra 100 bucks on a good quality digital thermometer/hygrometer from radio shack.
I havn't used the accessories, but have heard they are great as well. Goodluck!!
