Ok, just got done reading through the whole post. THE most informative forum post on growing I've read online. I understand most of this setup, but I'm confused with adding/mixing.

1. When pumping water from the reservoir to one of the grow buckets (to add water/adjust pH) will these buckets attain equal level? Or will the grow bucket overflow?

2. You said you mix the solution in the buckets w/ the reservoir before checking pH right? How do you mix buckets? During mixing will the buckets maintain equal level?

3. Also to be sure, the reservoir bucket has two drain valves right? One to stay connected to all the buckets in the series, and one to mix/add solution.

Thanks again RumpleFS for this thread/idea/gem for mankind! and everyone else for helping out.
