    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.

    I learned the hard way that letting the water temperature drop below 70F at night doesn't benefit the plants at all. While I was doing that I could barely get any growth in plants - most survived fine, but just didn't grow. Now, I have a heater in my small tank, set at 78F, and the growth is noticeable, which it wasn't before. Because my lights heat the water in my tanks, my summer water temperature gets into the low 80's F, but I have had no problems that I am aware of with that. So, I suspect the allowable temperature range is of the order of 75F to 85F.

    Thanks to everyone for sharing your experiences. I was just trying to narrow down what could account for such noticeable plant growth differences in my tanks. The same plants in the 27 degree celcius temperature seemed to be doing better than those in the 30-31 degree celcius temperature tanks. That is probably just a coincidence and not related. Mind you the plants in the Aquasoil II substrate with 27 degree celcius temperature seem to be doing much better(and best) than the ones in the non-AS II substrate so I am beginning to think that AS II may really be good as they say since all other things remain equal(duration and intensity of lighting, c02 injection, types of plants, frequency of water changes, fert dosing, etc.,) When I get a chance I will test and compare the KH, PH, GH, nitrates, and phosphates of all the tanks just out of curiosity.
