These are some snaps I started about three weeks ago. I read somewhere that they germinated well if kept at 40 degrees for a week and then brought into 75 degrees. I put them on my front porch for a week and then on a heating pad in the basement. The idea of starting them so early is to have a good early show while the weather is still cool and then replace them with other annuals. I have transplanted once and then put them outside on days when the temp is above 35. As you can see I lost some along the edges of the flat from wind damage.
