    Plants do better at higher temp?

    From the onset of my tank setup, i have set my chiller at 25-26 degrees celsius.... i got good growth and such from the plants especially the various types of moss....... but since i am introducing discus into my tank, i raised the temp to 29-30 degrees temporarily... hoping to bring it down slowly to 27-28 degrees eventually once my discus acclimatized....

    But I noticed that now the tank is at 29 degrees.... i am trimming more often! My vallis, tiger lotus, hairgrass, e.tenellus, java ferns are all growing like crazy compared to last time ......my moss growth seem to be slowing down though...

    So i am wondering, other than moss.... seem like most of the plants thrive in higher temp condition! Any comments?

    The discus provided more nutrients instead?

    erm.... been dosing No3 at 5-10 ppm and PO4 at 1-2ppm EOD...flourish 2 times weekly...... so dun think nutrient is an issue leh....unless there are some other component in the discus sh*t that is magical for plant growth?

    Perhaps higher metabolism?

    In general, plants prefer lower temperatures (assuming all other parameters are the same).

    Plant metabolism increases with temperature. Therefore, you may perceive an increase in growth rate when you increase the temperature. There is a critical temperature beyond which rate of metabolism exceeds the rate of photosynthesis, and the plant stunt/dies. This critical temperature is usually >30°C or even >40°C. However, mosses generally do not tolerate high temperature well, they will usually die off at temp close to 30°C or higher.

    so there is a range of temperature which plants do best at right?......I am suggesting the most of the plants... well... at least those within my collection seem to thrive at around 29 degrees......... which is around the average water temperature during day time....so....chiller is not really needed for good plant growth minus a handful of species......and of cos moss....

    So i guess at 25degrees, i am actually kinda stunting their growth potential..

    a good compromise for a moss+plant setup i guess will be in the range of 27n to 28 degrees. Agree?

    Plants do get stunted(I mean stop growing and not just growing slower) when the temperature is extremely low. 25°C is still a good temperature for most plants.

    Crazy plant growth isn't what I am be looking for in my tank. Lowering the temperature do benefit me in a few ways:
    - nutrient uptake is not as demanding, lower chance of stunting and algae bloom (I used to get lots of algae during the hotter months of the year when my tank hit 30°C)
    - no crazy plant growth
    - plants generally grow more compact
    - moss growth improved

    I am now not using CO2 injection. I find non-CO2 tank is more prone to problems at high temperature.

    Your light isn't that low in actual fact since the W/Gal rule is for NO FL instead of PC (intensity issue...more CO2 demand). As long as the light is evenly spread out, it should be fine. I did a comparison using eyes (no lux meter) between a 36w PC light vs 2x15W FL and it was clearly evident that the PC is very much brighter.

    Hmm i guess youa re right.... i dun think i want my plants to go crazy and start to become wild looking!

    BTW what do u mean by more compact? As in more leaves per stalk or more stalks per cubic square?

    update:
    after a period of crazy growth as posted above.... there seem to be a reversal of growth!
    at temp of 29-30, my vallis are actually browning and melting from the tips..... throwing off broken melted leaves everyday!......my bolbitis new shoots have been stagnant in that size and position for the last 2 days.....my moss no longer has the light green budding at the end of stalks...zero growth? Hairgrass and eT not sending out new shoots as fast........hair algae seem to be making a come back.......

    only my swords are doing well......5% growth daily!

    the light/co2/ferts regime is still the same as before the temp is raised..... din meddle much with the rest fo the tank.....

    my conclusion......... a planted tank at 29-30 degrees is not sustainable.....my tank is starting to disintegrate after only 1 week.....

    so pushed my chiller temp down to the current 27-28 degrees over the span of 1 day....... now keeping my fingers cross both the discus and plants can make it.........

    It is possible for the tank to work at 29-30°C, but less maybe healthy moss. You might need to tweak your CO2 and fertilisation to meet the increase demand. Your plants may be going through acclimatisation to the new temperature and are shedding some leaves.
