First things first, outstanding work. Doesnt sound like the pk i ran, i got a significant grape & complex red wine aspect to kushy aroma. Individual buckets are a pain. Connecting buckets to control with float valve fed by rez is a great way to keep evenly topped off buckets. Recirculating allows for chiller use if desired and maintains even ph and ppm in each bucket.
Drain should be incredibly simple, drop pump (some leave pump in there) into control and pump out..as easy as ensuring tubing is run to correct drain location and plugging in pump. Some just leave pump and drain tubing always connected and only turn in or off pump to drain out.
Trust your instinct, looks like you already pulled the trigger. Just know there are ways to simplify dwc operations if you ever have the interest.
