I suggest starting now, without the automation. I have a similar setup, of using grow lights, hydroponics, and some ol' fashioned dirt. But mine is made mostly of trash that I scavenged.

I print the 3" net cups, but the containers are old food containers, a shoebox with a broken lid, or whatever else I can find that would otherwise just get recycled.

It's pretty bare right now since I just harvested, but I'm about to start another batch of hydroponics today using some containers that are out of frame in the picture above.

And I admit it, I did print some flower pots just for fun. I wouldn't recommend it, unless there's something super cool about your design. It's far more economical to buy them.

I followed you so I can pick up some tips and tricks as you run into issues. I'm especially interested in yo what degree the moving water prevents algae from growing.
