I agree with the guys above. I used a Dennerle cable on my first planted tank-essential they told me....Well, one day I turned it off, and I didn't notice a blind bit of difference. I live in the UK, where it gets a little cold sometimes (you know, in between the rain), and just rely on in tank heaters now. The plants don't seem to get cold feet. I wouldn't bother.
