Hydro Schematic(Note Any Flaws)

I'm confused as to why you need all the tubing. Couldn't you just hook the supply from the main reservoir into the first bucket, then hook the buckets to each other and have the return from the last bucket go back to the reservoir? It would just make a simple circular circuit that way.... I don't know a whole lot about hydro, just trying to give you some feedback.

 

That would cause uneven watering, and it could drown the first plant and dry out the last one.

 

Agreed. Hook them up in series.
