Default Re: Automatic water change system design DIY

i plan to do something similar when I get a home (not an apt)

i think it would be much simpler and safer to eliminate the float switches, relays, pumps etc. and...

1. drill an small overflow on the back (no worries about breaking siphon)
2. use a solenoid on the water inputs w/ a timer (like 2-3mins daily) slowly adjusted until its right
3. have water outflow just lead to a drain or flower bed etc
4. have automated fert system
