One thing I have learned since starting, is that I apparently did not have the water level high enough to stimulate the roots growing into the water. I looked at other grows and saw plants half the size of mine with roots extending 3-4" past the basket. My plant is much larger now yet the visible roots are still unimpressive though it is very healthy. As the medium was always totally wet, I was afraid of overwatering or root rot. Seems the air exposure prevents that, so I added another gallon of RO water to bring the level up to see what happens.
