I think the plants love night temp drop they grow very fast and propagate too :-) Never tried not turning the tank heater off so cant really provide any experimental comparison to constant temps 24/7.

Thanks for providing those links!!!! I love statistics! Mind you, my water temp is 95 F, but the air is probably in the 80's. At night they are likely to be in the low to mid 70's when I turn off the heater. I think that as long as I do this consistently and give them time to acclimate, all will be well.
