Great thread!! I'm going to watch this one because I go out of town occasionally. A source for some devices is X10 for security monitoring and surpluscenter.com for relays,boxes, switches, and such. I'm working on a short term power source for the transition from hoese current to the genset. We lost power last night,. That woke me up..shot me off the couch..twisted my hip..All so I could unplug the timers somy plants wouldn't go schizophrenic with the interuption of *day* as i've had thatoccur before with semi-disasterous results, the girls went back into veg growth briefly, and i wonder why I'm losing my hair! I haven't read the full details, I will, and I'm going to work out my system with a former Cisco routing guru. The more deeply I get involved with growing, the more i want to maximize my yeild..besides, it's cheap(relatively) compared with my other hobbies.
