plastic cover covered with droplets. Now I have opened the slots, the
inside has dried out. I now want to plant them out onto compost under
lighting grow them on. How slowly should I harden them to this new
dryer environment?

Would a birch family seedling need to be hardened off?
Are they birch?

I am unsure, but if they are a native species throw them into their growing
space, lob a bit of soil on top and wait until spring. Honest, if as I
think they are native, don't worry.
Obviously if you want to spur them on a bit in growth, treat them to a bag
of compost. Sit back and watch them grow

He's not talking of hardening them off into lower temperatures, but into lower humidy - he's growing them in a very high humidity environment atm
