Best germination temperatures for kale, spinach, lettuce?
Just seeded 2 flats, 1 of kale and spinach, the other of lettuce. I know lettuce needs light to germinate (hence the very light covering of mix), but I've never grown spinach and I think I started my kale too early (or left it in flats too late) last year, that germinated well at 67 degrees. But spinach? Do all of these or any of these need cooler temperatures (my basement is about 50 right now)?
