Hey folks,
Great threat btw. I currently run a passive hydro setup, but this thread has me considering alternatives.
I have a question for y'all: Do you think it would make sense to utilize a CAP controller to flood a 3x3 tray? I have limited height in my flowering space, and would prefer to not have the tray sit on an 8-12" rez. I know the tray would have to be raised to the point that the highest 'flood' would be even with the top fill point of the controller.
I already have a food-grade barrel, so would not need to buy a rez. Another potential benefit is that I could keep the barrel (rez) outside the flowering area to maximize use of my space, and I could keep the nutrient temps lower.
Thanks for your insight.
