Onions from seed?

My onions are looking like they are almost ready for lifting, I have onions from seed, sets and heat treated sets, all looking about the same size, possibly I should have watered them a bit more, but not a thing I usually need to do, this has been an exceptional year and the ground very dry, had one or two running to seed but was more vigilant this year and removed any seed stalks right away, my garlic bulbs are not as big as usual but still ok
