<span class="link_user">@Willy_Balls</span>, Hello Willy_Balls! Yeas, i run sterile approach, its easier for me, using hypochlorous acid. I have Milwaukee pH58 - ORP/PH combo pen and Ali Express ORP/PH controller with 240v relay output for peristatic pumps (dosing pumps) . To be surprised cheaper work great also but with better probes. Probes for PH and ORP are also from Ali Express, they work two years for me and still working . This grow i want to try higher levels of ORP in flowering (+500mV) and even more in last two week (+750mV).
