The bucket array got it's plumbing put in today and I'm sure I bumped a few of the seals. Gorilla glue was really there are more of a structural glue anyway, and the plugs on the inside of the buckets are now healthily coated with silicone based caulk. Next time I'll just use PVC seal. Anyway, the pipes all went in great (top left), and even put in a water level indicator (top right).

The lettuce continues to grow at an alarming rate. (bottom)
