Since I can post pics, I decided to up date the thread with what the outcome looks like.

Behold "Fogfognugen" a fog/aeroponic growing machine.

138 plant sites per tray, 276 total sites.
Ultra-sonic fog fed thru large pvc and 8 mister nozzles in each lid for pressure misting system.
oldmac Reviewed by oldmac on . SOG technique; spacing I am in the process of building a new hydro set-up using fogponics, both dry fog and wet fog. It will be a SOG, fog to waste and I am using 2- 4'x4' trays. In laying out the lids, I was shooting for 4" stem to stem spacing using 2" net pots. I picked 4" spacing because that is what I use now with 4" rockwool blocks. What I'm finding is max number sites gives me 3 3/4" spacing or use less sites but spacing is at 4 1/2" apart. Which would be better, or what do you believe to be the best Rating: 5
