Outstanding thread!!….Question?..While I am having success using the tea with one particular undercurrent system, I am trying different methods with others that I have to ultimately come to a most efficient conclusion. In the setup that I have concerns for, I am running AN (w/o tea) and I am seeing wonderful results with it. But just 2 days ago, I performed a nutrient change (3 part PH perfect, B-52, Voodoo Juice and R/O) but failed to check my inline filter which is attached to my pump that pulls all of my water through my chiller. Nonetheless, it was clogged and therefore my temps ran high for about 24 hours. I checked the roots once I realized this and they were still pearly white but I could see some clear slime on a few of them but just at the bottom where they sit in the water (water level 2"below net pot). I know that the chiller will bring the temp back to normal but my question is do I need to flush with H2o2 or will the fact that I have corrected the temporary problem solve the issue at hand? My plants are 2.5 weeks in veg…..I was trying to avoid using tea and or H2o2 in this particular system just to see what works best….but if I have to I most definitely will.
