Where do you get these timers?I used a recycle timer for 1 min on 5 min off, or 30sec on 3 min off. Seemed to work well for everything from seed to finish.
i recently started growing and went from a aero/dwc hybrid to a more LP aero with no standing water in my root chambers and im running sprayers 24/7 with great results! healthy white long dense roots! but i plan on moving to HPA in the future, its much much more efficient with out loads of water for a big rez.Ahh excuse me he says hes going for aeroponics. So yes if you are spraying at +60psi of pressure and can generate sub 50micron water droplets then yes 15seconds on and 15mins off. If you are however not using the kind of caliber equipment that can produce a true aeroponic environment then all this is nonsense
