Is there a specific or ball park temperature range that is considered ideal for plant growth. I read that mosses, like java moss tend not to thrive at higher(over 27 degrees celcius temperatures) and I have a co-worker who has java moss growing like a weed in his guppy breeding tanks at a consistent 27 degree celcius. With all other things being equal, I am also finding that the same plants in my tanks where the temperature is 27-28 degrees celcius seem to be doing much better than the ones with a conistent temperature of 30 degrees celcius. I know that cause and effect relationships are difficult to conclusively proof but has anyone experienced anything similiar. Thanks.
