Starting tulsi in winter(holy basil or ocimum sanctum)

Hello there

I have some tulsi or holy basil seeds.
I sowed them on surface of peat pellets, but they have not sprouted. It is already two weeks. I read that they should be sowed only in or after march.
Is there some way around to get them germinated in this month of Jan.
Can I try to sprout them by putting in between the sheets of damp kithchen roll and putting them in a plastic container?
FYI, I live in Germany.

Please advice me on this.
Thanks in advance
