January is much too early to start sowing most seeds, even in a heated propagator they don't really thrive. Chillis however, do need a longer growing season in the UK where we don't have enough light or heat to give them the best. So I have bought a very basic grow light. The bulb is specially selected to be multi spectrum light, containing the right sort of wave lengths to mimic real sunlight.
I will make a foil reflector to go around the heated propagator just to take advantage of all the light I can. I might grow a few early herbs, lettuce and quick crops just to see how it does. Any suggestions?
