Re: [GSAS-Member] Oops, correction

The idea with the substrate heating is that the roots of the plants are 
stimulated to grow.  Most people will measure a temperature difference 
in the gravel bed of their tank if it is reasonably thick (say 1 inch or 
more), where the temperature of the gravel is up to 10 DF lower.

While this would probably help plants toward their optimal growth rate, 
I feel that it is generally an expensive thing to do.  One can get 
excellent growth rate in plants by providing everything else; proper 
nutrient balance, proper lighting, proper fish-load, etc.  Doing this 
(without the heating/substrate cables), your plants will be growing so 
fast that you will need to prune them weekly.  And let me tell you that 
it starts becoming a chore!

If it were me, I would invest a smaller amount of money in some good 
test kits, and some good dry nutrients.  YMMV

Cheers,

Mark
