Northern Lights Auto DWC

Transplanted to DWC around 4/11. Just going with the single bucket until it's inconvenient to move the plant, it's not a big deal for the first few weeks, and buys me some space in the tent. My pH meter is busted, errr, it "works" but it won't calibrate, and it's reading off on the reference solution. I even bought new reference solution... Still off. So, probably the probe is bad, oh well. Buying a Apera ph60 so I can replace the probe next time, I'm also happy to have the backlight, that was always painful to not have it, like looking at an old school gameboy. Welp... wait for the roots to drop! This time of the grow is... slow.
