How do you all collect the run-off for testing? I am using 5 gallon buckets and placed one of these under each.
Not so hard now, but as they get bigger, I can see where it will be a pita getting the samples.
Another noob question. When I water/feed them, do I water/feed until the juice drips out of the bottom every time? I would think that we would want to test ppm & ph every time. Correct?
