GBuds, about the neoprenes, I use them and no media, but you can only do this if you have some other way of holding the plant up once it gets too big for the neoprene to be able to. The 3" neoprenes are completely worthless, I use only the 2" EZ clone neoprenes. (fit in a 1 7/8" hole) In flowering, I have the trees grow up through chicken wire, that holds them when they get bigger.
With no media, it is so clean and easy to transplant, and the entire root mass is in the bubbling solution, instead of the part with the media being above it. Also without media, you can visually inspect the entire root mass. And, I would bet that the plant grows faster without media too, at least when it's first starting out, getting those roots out through the media into the solution.
As far as tds or ppm, you really just have to keep an eye on it. I just took a guess at what some seedlings would want, got it too low, now I have deficiencies already, really annoying. Lol. Going from 400-600 not even 2 weeks in wasn't enough, I'll probably hit 900 in a few days. That's with a 7/5/12 ratio of botanicare's cal mag, liquid karma, and pure blend pro, and reverse osmosis water, strains white ruski and thc snow. Another thing about that, it is system dependant. My small veg setup, which prevents the roots from becoming entangled between adjacent plants, also puts a crimp in the roots' style, so to speak. The roots are forced to stay in 3.5" or 4" vertical tubes, and that requires a higher tds than an unrestricted setup. 900 in that would probably be about the same as 600 in my flowering setup, once the roots get big enough in that little veg setup to be held back by the tubes. So yeah, you really just have to keep an eye on the plants, they'll tell you what they want..
