Might be watering them inadequately, missed the peak growing season, which is summer (most likely, though some are still growing) impatient or all of the above but I feel like that’s the size they grow, apparently I’ve read somewhere that they’re of the “ornamental” variety which means they’re that size when they’ve matured, but the picture shows a bigger size. They’re Thai Dragon Chilies. Unless I wait until next year to see if they grow bigger or to move them to a bigger pot.
They don’t get a ton bigger but they look immature to me. Particularly the one in your hand.
They need heat and light and have a relatively long growing season in non-tropical climates. My chilis flower in may and I harvest end of September.
Yeah I guess that would make sense also, just need to invest in a greenhouse then maybe 😅
