spugh22; take account of the breeding of your onions. If they are F1 you may waste a lot of your time growing the seed only to end up with useless plants/onions.
If you want to experiment, fine, but it may be better to buy good quality seed or sets.
If you plant onions that are growing roots, of course they bolt. Onions are biennial and always produce flowers in their second year. Nothing to do with the weather.
