Yep it would become a mess. But this is a common practice. They simply run the water through sand based filters to remove particulates from it. That could be dead roots, algae, dirt and dust or chelated nutrient solution. This is a common practice also in aquaponics. They don’t feed the actual fish waste to the plants, they filter it and then allow the water soluble nutrients to feed the plants.

The biggest boston (dome) lettuce factory in the world is close to where I live in Montreal and they said in a news report that they never change the water, it flows and gets oxygen from the pumps and they replace the water that the vegetables absorb but that’s it.

How is that possible ? Wouldn’t the water get filthy after a while ?
