Everything looks pretty cool I'm fixing to make one myself but lead in the water is not a good idea

7$ deburring tool will help make those holes way cleaner

I hope you're going to seal the sides of holes where the fittings are!

I can't find bins that stack like that

Water will be sitting on the lower part of the bin 🤔 should have placed the flood fitting at the lowest part

an air stone isn't necessary for ebb and flow since the pump is running on a timer. once the flood cycle is complete the water will drain and oxygen will start filling up the roots pushing nutrients and oxygen up into the plant.

Is the parts and glue food safe?

Where is the part 2 man?

how the hell do you own a vertical band saw but not a hole saw lol.

Weight, not hook.

Dwc much simpler und cheaper und efficient

Your lack of proper tools is disturbing.
