Rockwool/Root Riot + heated propagator - safe distance from bottom?

Im using root riot cubes and a heated propagator and I was just wondering,
do you have the cubes sitting on the bottom of the heated propagator or would you have to have them raised up so they are not touching the bottom(same would apply for rockwool cubes)? If so, is it ok to line the bottom with hydrton?

In other words, will a cube touching the bottom of a heated propagator dry out too fast or damage new root growth?

Any advice appriciated
