Thank you all for such comprehensive thread.
I’m now building an aeroponic system for basil using vertical pipes and HP misters.
But now I’m thinking about using ultrasonic foggers. Such an idea is extremely tempting because you do not need to use all these tubes, accumulators, high-pressure pumps, etc. After reading some information (including this thread) I see next disadvantages of using ultrasonic foggers:
- heating. Maybe solved by using water coolers (like these ones that used in saltwater aquariums for keeping the water at the same temperature). As for cooling a root zone using fans - I think it is a bad idea. The biggest treat of aeroponics is a roots dring out. And with fans + extremely fine mist, such situation will become more probable.
- clogging. IMO it’s not a problem to clean these foggers once a year
- roots pomping. IMO this is the main problem. Due to an extremely fine mist that US foggers produce, plants start to build huge roots, that may finally close tightly all the space. An in my situation (growing basil in vertical pipes) there will be a bottleneck for the fog to spread through a pipe.
Could you please comment on my thoughts?
