Where are you buying seeds from?
Baby Bhut
Nothing from my jalapenos yet, they have been in the compost pots for about 4 weeks now, I have them in a makeshift green house/propagator consisting of a large Tupperware and some cling-film with holes pierced in it, sitting beside a south facing window.
Time to buy new seeds or wait it out another few weeks?
Looking good Neil. Mine are similar size, so no stunting or trauma in yours.
I leave mine in very small pots until they're root bound. Good tip for potting on is don't do it too early.
I also don't feed them until they're big enough.
It sounds like they might be struggling with low temps, assuming there is no heat other than the window. They like warmth and I have previously resorted to putting them on top of a broadband modem as a heat source. In short, check temps and if constant warmth is present, probably need need more seeds. If it is cool/cold part of the time, try constant warmth. Here you go, just found this (repost):

I could always set up a mining rig under it, they seem to make plenty of heat.
