What do you guys think about using a running waterfall for DO production and agitation instead of an air pump with air stones in a undercurrent system? Anyone who knows fish tanks will know of the over the back filter systems that add oxygen and produce positive bacteria. The point wouldn't be for bacteria but for DO production in place of air pumps.
Then instead of running airstones to each individual bucket I would run 1 inch PVC from a manifold connected to the non-submersible pumps positive pressure to the top of each bucket. I would drill a number of holes in the end of PVC and cap them off. This would then create pressurized streams of water to add DO to each bucket through surface agitation.
Everything else would be the same as most other undercurrent systems. 2" return PVC at the bottom of buckets connected to 1" hose that connects to the "in" side of the pump. 1" hose would run to manifold then 1" pvc would run to the tops of each bucket and reservoir. Adding DO to system water through pressurized agitation from streams created by holes drilled in end of pipe.
I've been reading that for a number of reasons DO production through air pumps and stones is the least effective means of adding oxygen to system. There is also the side effect of adding hot air to the water, root system and inside of buckets as well. I actually found two different threads on two different sites that tested DO with meter. Both found that out of 4 different ways of adding oxygen airstones and pumps were by far the worst.
I gathered the above idea from reading a few posts and most of all from DGP's systems.
I was also considering running my air conditioner in a separate room just big enough to hold my reservoir and air conditioner and a bit of space for cool air. Then I would run ducting from the cold room to the grow room. This way I can cool the room and the systems nutritional fluid for the same energy use.
