I have planted some mint seeds in a couple of pots and fortunately they germinated within a reasonable length of time (4 or 5 days, if I remember correctly). But the sprouts are somehow slow to grow: it is a week now but they seem to grow very slowly. I wonder if that is natural for the mint? 

I have used good quality soil - at least I was told so - and water the small pots every day. And I have put the pots behind the window on a table.

Here's a photo:

Any suggestions for their faster growth?

Thanks
