Third system

[txice]

Nice looking system GpsFrontier.

You know...I see alot of designs using a setup similar to this (be it ebb and flood, nft or what have you), and I'm always curious about root management. Having experience with these types of systems, how to you manage that, if at all?

I mean, I'd think the roots could very quickly get out of hand in a small-ish tube like that, especially if the plant was something intended to be kept for a longer term. Do you perform any sort of root maintenance or simply just let them go? If it's the later, do you eventually end up encountering any issues at all with the tube clogging up or anything?
