In the past week, the branches have more than doubled in size and are now growing branches of their own.
Adventures in growing Sequoiadendron giganteum (giant sequoia) trees from seeds.
Seed #6 has always been the tallest. While under the grow lights, it's really grown significantly, now working on its first branches.

Another little guy that's done just fine under the grow lights. I gotta say that if not for the lights, I think I would have lost half of my seed seedlings while on vacation. They weren't growing very fast, and the damp peat moss was starting to damp them off, rotting the roots away.
After three weeks under the grow lights, just about all of my seedlings have taken off, growing several sets of secondary leaves. Before the grow lights, their growth had slowed to a crawl, and they were starting to damp off.
I just dusted off my old tripod, so I thought I'd try some extreme close-ups. This little guy is still my favorite.
This guy was my first to show secondary leaves, and since then, they haven't stopped showing off. In another couple weeks, I can start giving this one tiny amounts of direct sunlight, and shortly thereafter, diluted fertilizer.
Looks like this one's going to make it after all, despite the shriveled cotyledon. You can see the secondary leaves pushing out from the center.
