If I understand correctly you are going to use a blubber/air pump to do what is basically a drip system, and they will be getting the water/nutrients from above. As long as they are dripping fast enough to keep the roots saturated there is no need to keep them submerged into the nutrient solution.
Although if you are planing an system where the plants roots are submerged continuously, and adding the air bubbles to the nutrient solution so the roots get enough oxygen/air. It would be best if you could design it so the water level is adjustable, so you can test it at different heights. But a basic rule of thumb is that you want the water level high enough to submerge all the roots but not so high that the plants develop stem rot. Probably somewhere between 1 and 3 inches depending on the plants you are growing. My pepper plants seemed to do fine with the water level about 2 inches below the growing medium. My strawberry's were more tricky because they don't have a single stem but rather a bunch of stems coming out of a ball, but I tried to keep that about 1 1/2 inches below the growing medium. I didn't have a way to adjust the water level on my strawberry's until I redesigned that system. Hope this helps some.
It would be great if you could post some pictures when you get it all together....
yes, my system will be the latter one that you mentioned. based on what you said i guess the water level should be just below the net pots.
i will definitely post pics of the system once i get it going and the plants are big enough to see in a photo. i am still waiting for my grow tent and seeds to arrive so it may be a month or two until pics will be available.
thanks for the help.
