Hmm... Well, I guess a single bite counts as "growing something I can eat". I'll give it another day (till it stops raining and isn't as cold outside) and cut it off. I should have paid attention to the seed packet more and given the plants more room and sunlight (or growlight). Well, I learn! And thank you for the insightful comment!!!

P.S. I think I found an offshoot right next to that tiny head. I might be wrong, but I will cut it tomorrowish. Learning new stuff is fun.
