My onions are in flats that I put our on the porch every day it is above freezing, once they have sprouted.
I keep them in until they sprout then work on hardening them off right from the get go.
Onions are one thing I’ve never tried from seed. I usually buy ‘sets’ which are onion bulbs that I direct sew once my soil is warm enough.
What variety(s) have you started? Is it one you’ve planted before?
I have tried seeds and sets and never had them develop onions. Well, sets worked once, then never again.
We started getting a product from a grower, they come in bundles, they’re little plants, green with roots. Not sure what to call them, but they have worked for the last 3 years or so. They come in several different varieties. We have about 50 in the ground now.
But would they not sprout earlier if kept inside? I just filled about 75 large paper coffee cups with dirt and planted 4 different kinds of tomato seeds in them, but they need to stay inside for about 6 weeks after sprouting until they can be planted, though bringing them outside for a week or so before that for hardening.
And today hardly looks like Spring in NH and MA!

- nothing else has sprouted yet. (but patiently waiting...)
