I didn't check on them the first few days and was surprised to see that their were 1.5" high seedlings 4 days later.
The trays were on top of the bunny condo and the seedlings were bending over toward the window. I rotated them right before taking the photos. The early risers are: Radishes and broccoli rabe that are now 5 days old and 2" high, followed by 1" high ice lettuce, lacinato kale and endive. Romaine and a mystery green that I seed saved but didn't label are just emerging. Many of the seeds were a few years past their expiration dates so I'm really happy that so many have sprouted already!
