Canopy temp for LED

I am under the impression LED temps should be 80°-85°.
An experienced grower pointed out that temps should be 75° with LED.
I am new to the scene, so my experience is research/journal following, only.

Which is it???
75° or 80°????

Thank you in advance for any experienced input.
Peace

Everything is reality is slightly different and going to want slight [to major] changes in temp/humidity.... just like @PSUAGRO. keeps saying....just keep trying to read your plants, grower and they will tell you a whole lot! :peace:

I appreciate all the answers.
I'm my personal, breif experience, I found my girls to be happier in the 80°-85° range.

I am still curios to know what other LED growers consider optimal canopy temps, whether I decide to change or not.

Not sure who this PSUAGRO is...I shall look it up, thanks.
Peace.

I find higher canopy temps and humidity in veg is a plus eg 78-85°F,55-65%rh. Working in the proper VPD range gives better growth and less stress.

In flower i think better results when canopy temps are no higher than 80 with 75 being optimal. In flower i like 50-55%rh.

Another thing to keep in mind that initially as DIY builds were being put together...Thermal resistance and cooling of the LED fixture itself benefited it seemed best with an ambient temp around 25-27 Celsius [72-78 F] and that worked with with keeping Junction temps inside the LED itself cool...

as diodes [especially the CXB's] became more efficient and with more advanced cooling options to begin with....this is less of a concern with ambient and I think if you finding your sweetspot over 80F +, great....Don't be afraid to mess around with different temps too if you feel the need, it could be worthwhile :peace:

Thanks a ton. Tbh, I am baffled by alot of the LED jargon. It is my plan to familiarise as I would love to do a DIY some day.

I initially bought a "150w" Advanced Platinum, 100w actual.
I wasn't impressed.
I felt, (2) 26w 6500k & (1) 23w 2700k did a better job during veg.
I bugged a member here, whom I regard as an expert in LED, and he gave me a few options.
I settled on PLC CX300. So far, very pleased.

You guys will more than likely see me in the near future asking for guidance in the DIY area. :)

Thanks again to all of you. Much appreciated!
Peace

I Don't think its that difficult. But then again I am headlong into my first DIY after purchasing a sub premium falsely advertized "Deal" on a 400W led.
