Hi, wondering if I should be using a warming mat once I put seeds into soil? Thanks
Warming mat

As long as your room is above
20 c you should be ok. Be careful with those mats. They stay on 24/7 unless you have a stat.
They can easily overheat a small girl and kill her.

I put mine in a tray which adds a little space between the mat and pot.

I always cover my seed mats with fine sand before putting the seed trays on.
Like @Bill284 mentions some of the answer depends on how cool it will get at night or when the lights are off.
My method is mostly for when I am working up a crop of clones but it has worked for the occasional seed. I have a piece of 3/4 inch plywood I found in my wood stash. It just larger than the mat and any of my trays. The mat is on top of the plywood.
When the mat is on it will warm up that piece of wood which will radiate the heat back when the mat is not on. A timer controls when the mat powers up and for how long. Pretty much an hour on and and hour off for the night. Day or lights on schedule is 1 hour on and 1 1/2 or 2 hours off.
I put the tray on top of the mat. The trays are the ones that are about the same size as a standard heating mat. Small containers with the clones go in and I have two pint jars filled with water which helps keep the air and the very small pots of soil in the tray humid. Cover with the humidity dome. As a bonus I also put 4 to 8 cuttings in each jar and most of them will root.
In order to keep the humid air where it belongs the openings in the humidity dome are adjusted. It takes me about 4 days to figure out the hours on and hours off schedule. I try to maintain a night time low of 68-70 F and the daytime temp up around 78. The room itself drops to 64 or 65 at night and heats up to 74 or 75 during the day.
If your any good at wiring pick up one of these heat controllers
then you can wire up a water bed heater, battery blanket or heat pad and control it to the degree

Between the paper plate and cut down solo I never get past 83F and remove from mat upon sprout.
