Yeah, dats exactly what I am sayin, 'Hound. Holes at bottom of bucket, and they are daisy chained together. Drip in top, drains out bottom back to rez. I thought easiest and since SS dont have cash to be buying all the stuff to do controller for rez. Hydroton and them mega monster net pots on the buckets and big ole plants.

Rez change time comes, hook hose to pump, empty to shower, refill and mix. Simple as that!

SS, and once them plants get rockin you are not going to be able to go with changing one bucket on a 9 day cycle. You can forget that. They are going to drink a lot. You are going to be mixing and adding daily would be my guess to keep water level and nute strength where ya need it. Plus your pH will rise as sure as god made green apples (quickly) because of the small volume of water I would assume. And once your pH goes up to around 6.2 or so your plants lose ability to uptake P and K which they crave in flowering.

LW had what you want to do down to a science. Need him to toss some more ideas out. Wonder how he controlled pH.
