I have just been reading the link for "Flithy Fletch" for his 30 minute 6 pot aero build The 30 minute 6 plant aero build
and i want to make a similar one for veging some plants whilst my main area is in the final flowering stages so i can have a better turnover.
But because i have so many electrical things plugged in for my main area i was thinking of using a few computer fans on 9volt batteries to save on power. But my question is does anyone know where i can get some mini timer switches for these, or should i just let them run until the batteries run out?
