New plants, being born, need to stay in a moist ambient, as they lose water by the leaves, the roots must feed the leaves again. They are too young to all this water demand by the roots! You should cover it with a plastic box or something so the they stay with less luminosity, less wind, less water demand, etc.etc....
Also pay attention not to overwater your soil...
Also 32ºC will be hard for a seedling to survive, it just need a little luminosity and moist condition, above and below.
Wish you a great grow!
