Actually no Tris, they just stayed indoors uncovered for a week, then they have lived outside in shade now we have heat (29C today!) and have been watered again. I made the indents quite deep so the seeds are probably surrounded in moisture for longer.
Transplanted out my Kelsaes yesterday and they look really healthy. Five days of warm weather should mean good chance to settle in without stress. Also put out 120 Sturon sets after firing them in module trays. 10 rows of 12 each 10-12cm apart, 20cm between rows.
