I have used an undergravel filter and had no worse luck growing plants than
I did without it. I think the general opinion is that while UGFs don't
harm plant growth, in no way do they improve plant growth.

As a side note- Several years ago in Aquarium Fish Magazine, there was an
article that discussed the use of kitty litter for growing aquatic plants.
Kitty litter is a lot like an UGF- it doesn't hurt the plants, but it
doesn't help them either. The author stated that kitty litter doesn't
contain any nutrients beneficial to plants. There is actually a potential
for harming the plants if you make the mistake of buying a perfumed brand
of litter.
