Al, thank you, thank you, thank you for all of your help. I'm sure I'm becoming somewhat of a pest with all of my questions...
but, I'm trying to copy your setup as exact as I can (with some tweaks for my space I guess). So I did some math. Your tables are 2'7^ (820mm) with 23 6.9'' (175mm) pots in each tray. 2'7x2'7 = 7.29, and 23/7.29 = 3.15, meaning you have 3.15 plants per sq. ft. All of this information is based on a post you made in the original thread on pg. 52, and with all of this said, I'm going to be shooting for the 3.15 plant a sqft. that you have. However, you just said that you try to hold your plant count down to 2.5 sq ft. So, I'm not sure if I missed some adjustment you made to your setup (table size or plant number) as I was not able to read the entire thread.
Moreover, I really can't get around the hydroton/fytocell problem. I don't want to have to go to the hydro store or order off the internet as often as this setup would require me to, and I don't want to have to deal with disposing of this stuff either (not much of a problem with the fytocell). So I think I'm gonna construct or buy 4 4x4 aeroponic setups. How do you feel about aero? I've run a DIY aeroponic system myself before, but never doing SOG...
