Temperature help

I think running temps above 37c is very dangerous. I would leave them on low power and still think about adding co2....

What would be better please friends, they have always flourish at 31⁰c with great results as they love the higher temps, my thinking is will I lose yeild or potency at 800w compared to the normal 1200w or do I try it at the 35-37⁰ with co² thanks for your help 🙉

Hi there! The optimum temp would be somewhere around 25C if no CO2 is added (normally ~300PPM) and above this the photosynthesis will slow down and everything else will get slower too so the closer you can be at 25*C the better. And temps reaching 37C are nor good for the plant and I think that soon enough you will see burning and deficiencies and stress etc. It is just too hot for the plant and therefore the added watts from the lamps are not usefull 'cos the plant is probably suffering and not growing normally. You can download the lux meter app to your phone and check the lumens of your light at canopy level. The plants have an max PPFD they can use so adding too much is not even beneficial
