lol.... well, I don't have any giant redwoods anywhere near here. The grow medium is MG potting mix. But yeah, it looks like a tree sprout to me too. Had some hellacious seeding going on with the wind blowing a couple of weeks ago. I'm guessing that a tree seed made it in there last time I took my seedlings out for a field trip. I'm yanking it.
I just wanted to make sure it wasn't a pepper with some crazy traits before I yanked it.
