any driver at 220V is considerably more efficient than a driver at 110V, and more of a difference than the slight voltage drop lost from remote driver mounting (which can be overcome by upsizing conductors)
driver distance is a factor but a relatively minor factor
how much would i lose if i would mount the drivers outside and have say a 3m long cable to the panel? (i'm at 220V)

ac input voltage is unrelated to the voltage drop on the DC side
on the dc side, factors in determining % of voltage drop include current, wire size and distance
you can calculate % of voltage drop in any circuit with this info:

Temperature is ranged not a specific number or target. Every plant responds differently to the same environment. Your plants will tell you the ideal temperature if you pay close enough attention

No they don't. Plants are fine with anything between say 20C and 35C. That's a range yes, but in the end there is an optimum temperature determined by the humidity, amount of light and whether you supply CO2 or not etc. The plants won't show you which is the optimum temperature. They are still fine with pretty much the whole range. It's just that they produce more at the optimum temperature rather than anywhere else in the range.

Hi @VegasWinner,
to what should I pay attention ?
Until recently I lived in an appartment under the roof and used HPS, temps ranged between 22C and 30C+.
Except for 30+, I didn't noticed big differences (no CO2).
The I read that with temps under let's say 25C and leds plant metabolism will slow down ?
Hi @wietefras,
I know I'm overthinking, too many monthes without growing
Also excited and a bit worried about switching to led !
Have a nice day !

room temp and res temps are different.

yes, but won't res temp be to high in a 28-30C room.
In hydro/HPS, with temps in the room 30+ ( no idea of res temp ) I had roots problems.

want to try diy SIP, so no chiller. The grow room is not in the basement, no concrete and I don't expect the floor to be cold.

Your plants how they appear are leaves droopy pointing up etc. Your plants will tell you when they are happy or unhappyHi @VegasWinner,

Hey sup guys,
I noticed three was some interest in having the driver outside, which made me look at my data to see how much heat they were adding to the room.
For your interest, my driver room is about
2m x 3m with 2.3m ceiling.
I have 24 x 240w drivers in the room all blasting at their max with fans. So the heat is very evenly spread in the room.

I'll try again. I think most people would see minimal difference with drivers on the light fixture

@drgroove not sure if you've already read this, but it seems to be a good read on the subject of heat when it comes to LED grows.

How
I don't worry about my res temp in my SIPS. They each have a 12 gallon res. The room temp is 75-82f. They love it. Side note: I also add an air stone in each one to keep the water oxygenated. Never tried without an air stone, so I do not have a baseline but they do love it.
