When they first start, the nutrient level goes up about a 1/4" from the bottom of the netpot, so the bottom of the netpot actually sits in the nutrient solution. As the roots grow down, the water level is eventually adjusted to about 1-2" below the bottom of the netpot. I like it that way because there is no media to get salt buildups in, so I don't have to worry about flushing the system.

If you're considering going hydro, I'd highly recommend it. It's just as easy as soil, but different. Whichever you decide, make sure it's tailored to your application because each has pros and cons in different areas.
