Plant the modules intact at the same depth in garden. Comditions are now good for plantIng out but I would harden them off for few days before plantIng them. Do this by leaving them outside during the day at first and then overnight.
I assume you have one onion per module joannep.
Prepare garden soil well incorporating a fertiliser like fish blood and bone. I like to plant about 4" apart in rows 15" apart. ...10 cm apart and 37 cm.....and cover with fleece. This protects them from pests and birds until they are established ( 2 weeks or so)
The best onions are those grown from seed so good luck.
