It is interesting but if you asked the same question on a mainly fish, rather than plants, forum you would likely get 24-25c as the average.
Yeah, it seams more stay sub 25C, the ones with temp control at least, as most pre-set heaters for tropical fish are factory set to 25.5C(78F).21.7 - 22.0 with an Inkbird. Of course different people have different livestock (or arent in UK), but I was't expecting a good proportion are >=25
I use a <"fool-proof method">.I'll assume everyone has checked the accuracy of their measuring device.
I press the back of my hand onto the tank glass every morning, it tells you whether you have a stuck-on or failed heater, and it is more sensitive than you might imagine to smaller changes in water temperature.
Vallisneria spiralis, lake Malawi. (East Africa)Would anyone care to suggest a plant (including native habitat) to put this to the test? It's worth a try but comes with no guarantees! If this doesn't work, I'll gladly declare it a resounding flop!
That's interesting, I'd have been inclined to let it drop lower at night on the grounds that it would take longer to warm up so stay lower for longer in the day time.Usually around 26~27ºC. During some warmer days it climbs to 29ºC. On the rare cold days, it may drop to 24ºC.
I would like to average it at a lower temperature, but my cooling device is a simple computer cooler, with limited efficacy. I set my heater at 25ºC because even when our nights get cold around here, we still get warm days, so to prevent >5ºC daily swings, given how hard it is to keep the tank cold during the day, I rather keep the minimum temperature higher.
