I *hope* I never said substrate heaters improved growth! My claim is that
they provide long term stability.

You could probably read into that something like "you will have improved
growth after 18 months in a tank with substrate heating compared to the same
setup after 18 months without substrate heating". But that only means that
the growth with substrate heating was consistently good over the long run
and we experienced growth problems after 18 months in a tank without
substrate heating.

Luckily, our house is airconditioned, so we can use cables all year long.
