I think people really underestimate how much work it is to maintain a community online. It's something that is so outside of my skillset and capabilities that I feel awe when I see it done successfully.

Echoing what everyone else has said, peppers love heat. Ours were started about the same time as yours and they look about the same. They don't really start popping off until they are outside, with room to grow and it gets hot hot.

Good job getting them started so early, I'm sure you will be rewarded once their established root systems are given the environment they need to thrive in.
