Wouldn't something like Minecraft Vertical Farms be more effective, specially because you could just have a basin a top of another basin, and have the water drip from the top one to the ones below, thus requiring only one pump to pump the water that collects at the very bottom back up to the top. Of course, having aditional pump to add more water to the system would be helpful but not necessary. The only problem that I've faced with such a design is the amount of mass that all together would have and the required flood strength to support such a weight. That being said, having smaller such systems for room like enviroments shouldn't have many problems.
