I have it placed just on one off the pots.. it’s 26 out and down to 28 now.. in
Refro is a blowhard, one day maybe he will get it but probably not, most others noobie trolls.

Anywhere in the light reads light radiation which has sweet fuck all to do with air temps and the reason it is so hot in the first place and the reason your ramping up exhausts and fans to try and cool.

Do some basic science first then google stephenson screen and see how the pros read air at the met office then come back and apply that to your meter.

Too many idiots on this site you will always fail to get the basics but light dosent directly heat air so omit all light indirect or direct as thats what your reading.

Maybe your educated enough and maybe your another renfro who acts it but knows shit here.

Good luck and please dont reply as i have said enough for you to sort out the science :-)

Wow! This is the first post I've read where someone claims @Renfro doesn't know what he's doing. That's gotta be one of the dumbest comments I've heard yet. He knows his shit.

I wasn't aware that our plants were living behind a stephenson screen. Pretty sure the infrared light is hitting them too. But hey, lets get out the IR thermometers and test leaf surface temperatures because thats all that matters. smh you can see I am being sarcastic there. it's not all that matters

but hey, ranting like a complete asshole that has some sort of personal agenda beats the fuck outta bro science any day.

This site has gotten so retarded with people making wild claims and starting arguments. I just won't play that game anymore. It's like if you come here to help and are good at it, all the little piss ants wanna act up and start shit. Well I will just ignore the piss ants, wild claims and bullshit. @Kingrow1 is on the ignore list now. Anyone that wants to listen to his crap may do so at their own expense now.

Hehe I actually have a seek thermal camera. How much difference in temperature do you think there is between the leaf, air temp, and where you throw a thermometer. For led it’s like nil. For hps I actually like to have the thermometer exposed because it is closer to the leaf temp. The whole point of temp is for photosynthesis. I get what you are saying about the difference between air and surface.....but I would argue that trying to read the air is the wrong. I want to get the leaf to about 70 degrees if I can...and I want to account for the ir that is hitting the leaf (so exposed measurement). Even if I was a total screwup and just threw the thermometer in a random spot about canopy level (shaded or otherwise) what do you think the difference in measurements will be assuming a little air movement? (Hint it’s not that huge of a difference) certainly not enough to have that much of a effect on the photosynthesis level you are trying to measure (ie a few degrees of difference = a few degrees off in effiency. 90% vs 86% or 55% vs 53%). And if you are even close to optimal temp the curve is pretty low so if your off the impact is little.

I guess I just cant see why you keep harping on this. Technically your correct...but it’s like saying there is a huge difference/impact between 34 and 36 mpg in a car...yea it’s a difference...but really it’s so minor it adds up to nothing over even a year.

Oh no Renfro drunk, haha. Just kidding man. I love my Bud and Bud (Budweiser that is). Nothing is better than weed and alcohol, perfect combo, lol.
It's a prefect combo to some people but like my wife is bi polar 2 and if she drinks it messes with her meds and make her suicidal depression worse like weed doesn't mess with meds it really works with it so it just depends on who you are and what's going on if alcohol is ok for you or not

Ya I'm not saying alcohol is a good thing, but it has a synergistic effect when combined with weed. It is a depressant though, so not the best for someone already depressed. Weed is much less harmful if you ask me, and I hear ya man.

Work that brain harder - Light dosent heat air and passed straight through and heats any surface directly in the way.

So putting a thermometer in the light is WRONG as your reading light over air temperature. Ask why on a hot day it feels hotter outside in the sun than indoors in the shade yet the air temperature is the same in both.

Please do the science whoch Renfro dosent because he seeks only popularity and probably a product to sell one day.

Im right and the op is not doing it correct and Renfro adding more confusion which is un-needed if we simply dial back to basics.

why do i care about air temp. I care about leaf temp

Then learn the science behind it, leaves absorb heat from the air at 37°c and above and pass heat into the air at all temps below.

Inner leaf temps, stoma crypt temps and boundary gradient will tell you a lot more detail than your point and shoot....
