I am about to try to grow my first crop of onions from seed (variety Santero F1)
I want to sow them in those wee modules, or to give them their proper name, seed tray inserts.
I have an electric propagator, but this will only take two 'normal size' seed trays, so of course I am limited in the number of seeds I can sow. I have a couple of questions ...
Which size insert is better, 6 x 4, or the smaller sized 8 x 5 ?
I want to keep the onions in the cells until planting out time.
Once the seeds are germinated, I'll remove them from the propagator and leave them in an unheated / frost free conservatory. I could then start more off in the propagator.
My second question ... I saw somewhere, although I don't know where, folk sowing 4 seeds per cell, then planting out 'quartets' of onions. Does this work, or are the onions too small to use. Would I be better with just the one healthy seedling per cell ?
thank you
