Naga Chilli seeds

Last year I swapped some Burkina Yellow Chilli seeds for some Naga Chilli seeds. I have planted 4 about 10 days ago and 2 have pepped through. They have been put in the window by the radiator as the ideal soil temperature for chilli seeds is between 23-30 degrees. I have also lightly put some cling film over them in the evenings so counteract the chilly nights. Kept the soil moist but not wet and will now keep them in the window for maximum light. Hopefully they will grow into healthy strong plants. When big enough to handle I will repot into 20cm pots for this year, then depending on how large they are in the winter I will prune back and possibly repot into larger pots and place some organic plant fertiliser on top of the soil.
