chrysanthemum cuttings

I have taken some chrysanthemum cuttings. They are on the windowsill in a pot covered with a plastic bag to retain moisture.
Is this the best place to keep them or would they be better in the greenhouse on a heated propagation bench.
Any advice would be greatly appreciated.

Many thanks. GF.

 

I would keep them out of direct harsh sunlight, and I think that bottom heat (if your propagator does that?) would help
