Thank you, I appreciate it, you're too nice. Accumulating data helps me a lot because I don't have a lot of experience.
in uninsulated buckets (plain black with reflective top) the temperature is 3 degrees Fahrenheit below ambient. Insulated buckets (foam rubber under aluminum on the outside) the temperature is 6-10 degrees Fahrenheit below ambient. Both types have oscillating fans pointing at them.
The pumps are only on if the line pressure is low, below 80 psi. Nutrients are stored pressurized in an accumulator, and the lines up to each bucket.
LOL well that's relevent
