Saxifraga x arendsii 'Purple Robe'
I've been growing a little tray of Saxifraga x arendsii 'Purple Robe' indoors. They have germinated as shown on the pic below but i'd like to know when it would be safe to put these in the greenhouse to gain more light. On the seed packet it stated that i should sow indoors at 15-20c but not what to do after germination. I've only started to grow my own plants over the last 6 months.
