Good work, Hope you can keep your temps that low. I'm right there with you in the mid to high 70's rez temps in my veg room. I have to say I was a bit skeptical at first but low levels of bleach are keeping everything clean and happy. I was having a bit of algea and root rot in my last drip run this summer when temps were 80+ in my rez. 2 doses of bleach and it was all but gone and way cheaper and easier than hydrogaurd which is I believe chloramine based.
Scrogger, I'm running with the water level just above the bottom of the net pot as recommended by Heath and root growth is much more even and prolific. Yet another bong toast to the master...HM
Wait, you add bleach directly into your resorvoir? Even when you have living plants in it?
