I learned a lot through trial and error, mostly because I couldn't find a lot of detailed information on aeroponics.. there is some out there, you just have to dig.

Good luck on your new system.. for glue on mine, standard pvc plumbing primer/adhesive, with silicone to seal the end caps on the channels (made from 5" vinly fence posts). Everything can be fully disassembled for maintenance. Did you figure out the spacing of your plant sites?

Peace,
