I didn’t water to runoff the last few grows: autopots. There’s another way to make things easy and there’s any number of growers with journals on them. I can go 5 days without touching anything for 3 plants with the reservoir supplied.
If you use Jack’s and either top-feed on a timer (blumat) or bottom-feed like with autopots, the need to water to runoff goes away.
Do some research: search this forum and read some journals.
