George would be happy to have you (and anyone else in the Northern Colorado
area) visit. Drop me an e-mail beforehand to make arrangements.

The Krib archive of my "SST" series has a chapter on Lessons Learned (part
9, maybe). It describes experiences with many different setups, including
UGF, and is the precursor to the PAM4 article on heating cables and Why I
Love Them.  UGF was fine also, just not very stable - required bi-yearly
gravel vacuuming to keep it happy. But it grew most plants like

I wouldn't worry about roots getting caught in the UGF plate. If they get
torn when plants are pulled up for pruning, it's no big deal (you toss the
roots out anyway). If the plate gets clogged a little with the roots, no big
deal. You don't want a lot of flow anyway.
