Habanero Chili Peppers Not Fruiting

I bought habanero pepper seeds last year from you people. Everything grew very well and the plants had lots of buds and flowers but will not bear fruit. Can you send me an idea of what I am doing wrong. I have them under grow lights.

You may be growing in too sterile an area and therefore lack any pollinators. Try using a soft paintbrush to transfer pollen from the flower of one plant to another flower on a different habenero plant.
To stop young fruits from aborting, the temperature has to be kept fairly high. Try for at least 10 to 15 degrees Celsius night temperature.
