Cloning question: what's important? Root zone temp....or the ambient room temp?

When cloning..........
Is it the WHOLE CLONE itself that need to be in optimal temp range?
Meaning....does the room itself need to be in optimal temp? OR is it JUST the root zone temp that matters?
I'm trying to root clones now in chilly December in S. California. Our temperature is 50-60 F.
I'm using Jiffy pellets, humidity dome, and heat mat set to optimal temp range(75-79 F).......zero roots in 3 weeks.
Wondering if I need to warm up the whole room instead of just the root zones.
Thanks for all the answers in advance.

Put it all in a big cardboard box. Use ir temp gun on plugs for around 80f.

I see. Cardboard to keep the heat more constant. Makes sense.
So, I guess it's the temperature at the stems buried in the plugs is what matters, and not of the whole cuttings.
Thanks.

Did somebody mention cardboard.......?

I run a bubble cloner,did the cube dome thing way to finiky.Keep water 76F no dome no ph ing room temp at 72 no hassles.Simple as it gets.

The most important thing is the mother,healthy and not jacked up on food.You can tell a good clone from ann overfeed one by how long it takes to yellow after cutting.

roooot zoneeee....I've seen the worst mothers and weakest clones turn out to be monsters. Roooot zoneeeeee. 10000%
