Hello Farmer Rich,

As I said before, somewhere else, this is a very nice build. Nice set up, very simple which almost makes it elegent.:thumbsup:

I'm currently setting up a aero/fog grow tray, and have been foolin around with aero for the past 18 months. I would like to point out that even tho my system is probably more complicated, it does do away with most of the problems that have been raised here.

1) root rot; by using ultrasonic fog I have eliminated all pathogens and nasties from the root zone. Ultrasonic fog is not just sterile, it will sterilize the root zone for you. No green alge, no brown slime... no nothing. (root rot can only survive in a 1/4" zone around the stem and neoprene collar)

2) resivior temps; I do aero/fog to waste, there is no temp build up since nutrients/water are in 5 gal jugs and the temp is whatever the jug is. Plus without recirculating anything you eliminate changes in Ph and PPM and if you do have unwanted crap start to grow it won't be spread thru the rez.

Many advatages to going aero, at least that's the way I see it.
