An undergravel heating cable should improve the growth of your plants,

For more plant advice, rec.aquaria.freshwater.plants is good.

Please let us know how it turns out;

Undergravel heating isn't as popular as it was 10 years ago. People who
have tried it say it doesn't make much difference. I would spend money on
a good laterite substrate instead.

People have a variety of opinions on undergravel heating cables. I've seen a
few planted tanks with the undergravel heating cables, and the plants were
very lush and beautiful. On the other hand, they may have done just as well
without the cables. The theory is that heating the bottom of the tank causes
more water flow through the plant roots, increasing the amount of nutrients
available. Does anyone here have results from any experiments to support
whether it improves growth or not ?

I do strongly agree with using laterite though, my tanks have vastly
improved since I began adding laterite to the substrate.
