The brassicas—cabbage, broccoli, cauliflower, kale, and so much more—are satisfying at seeding time because they usually come up quick. This tray of Early Dividend broccoli is popping only three days after seeding. I don’t take notes about days to germination, except occasionally here on the blog, but I’m surely watching, especially with older seed. So far this year, with the seedling room usually around 65-68°F (18-20°C), the trays covered with clear plastic, using new seed, it’s been brassicas in 3 days, onions starting around 5. Where brassicas usually come up all at once, over a couple of days, onions can take a week to emerge right across a tray… Details! They’re everywhere! Some seem useful, some seem not.
Stellar photo! My broccoli seedlings are horribly leggy even though I use a 400watt metal halide grow light. Peppers look great as well as the tomatoes yet the broccoli is leggy, maybe its to hot. I planted some bok choy and it germinated over night, that was pretty exciting.
Lovely photo! I am new to gardening, and get ecstatic over my seeds so far, it is nice to read that the experts still love to watch the seedlings come up. :-)
