Hey John, how are you going to plumb in the win barrels?
The grow bed will be raised and partially positioned over the tank to drain back via a standard overflow standpipe (timer based)....
You can see that the grow bed has a couple of small holes in each end...

One end will be plugged.. the other will have a 19/13mm reducer fitted into it....
From that we'll just run a 13mm tube spine between the barrels and tee off into each barrel...
Each timer cycle will deliver a small amount of water during the full flood stage...
We'll fit a small valve to control or shut off the flow... depending on season, heat, evaporation and/or moisture of the barrels... the barrels will drain to waste any excess water...
The hole in the blue tank is being fitted with a float valve to automatically top up as required...
