I have done quite a few DWC grows (Shallow water actually= SWC). These days I only use it to start seedlings/clone. Once the roots are big enough I transfer to F & D because, F & D allows me to check water level, pH, as well as easily replace/replenish nutes.
Where I live it's hard to keep nutes cool, so I replaced the kitty litter tote with an Igloo cooler
And since the last picture I made new plant totes with the F/D tubing on the bottom and added control valves to make sure each tote was getting the same volume of nutes
Here's my simple DIY
