Fantastic results with my Bedfordshire Champion onion seed which I sowed on Boxing day. I gave them warmth from a heated propagator in the greenhouse for a couple of weeks.
Then last week when they had germinated I took the top of the propagator, and today they looked quite a bit bigger so I turned off the heat on the propagator. I want to begin the process of hardening them off very slowly. I don't want them to get pale and spindly with all that protection. In the next couple of days I will pot them up into individual modules to give them some more root growth. I've never grown onion from seed before, always from sets. This is the way it is done for the show bench!
