The broccoli and chamomile seeds were the first to sprout. I first saw green on Wednesday... just 3 days after planting the seeds. The rest of the seeds did not waste time catching up, though.
I think I noticed my first mistake in making this container garden: I used all the seeds in the packs. It's hard to realize it when the seeds and plants are this small, but using all the seeds in these containers will make it very crowded once they are mature. The broccoli, lettuce, and cabbage are going to be packed like an Osaka Loop Line train at 7:00 in the morning. Oh well... live and learn. Besides, the Internet says the fittest will survive, and the others can be cut and thrown away.
