What do the plants look like?

I'll rephrase the question. What do the plants look like? Are they happy? If so, I wouldn't worry too much. Keep doing what you are doing. Now, if they aren't happy, then sweat it a little bit.

But in comparison to a vpd chart I’m off badly

Vpd should be a guide, not a strict parameter. Get your temp dialed in, do what you can with the humidity, make your plants happy. It's good to understand VPD but don't worship it.

VPD can be a bit misleading. A colder space perfectly dialed in (with vpd) doesn't necessarily mean a better growth rate than it being off at a higher temperature. Theres more to it than that but thats the jist of it.

How large is you grow space?

Don't worry about VPD too much, just keep the plants happy. I try to follow it when I can, and when I can't, I absolutely do not stress about it. Listen to the plant and it will tell you everything you need, the only way to learn the language is by growing.

Your primary concern should be temperature; seedlings will struggle at such low temps.

Wee tip to is only fill the small pot up half way then you fill it up and bury the stretchy stem in a few days

Before I had the heat pad I was using a coke bottle
Boil the kettle
Fill the plastic bottle
But careful not to melt it
I used to put the bottle in a cup to keep it upright while pouring the boiling water in
Done that a few times a day
Annoying like but wee plants loved it
Better than them being cold
