I've never tried it but I would think that plants should do well in a setup like that, especially when the roots get under the plating and are basically resting in mulm.
Works fine in my 4 planted RUGF tanks. Yes, the roots of deeply rooting plants can get into the filter plate, but so what? I don't see why this is a big deal... So far, I've seen no damage, only a few tangled roots. I'd recommend 2" + of gravel over the RUGF plates.

Yep and they will grow there in a couple of weeks.
Roots systems on my sword plants are 6" plus in length and having as many as 50 root stems spread out under the filter. I dont care about that cause I dont move my plants. I have like 3" of gravel and am really happy they are there to absorb all the nitrogen and bad stuff down below. I think many plants are necessary for a successful UGF system.
