Yea, it is best to bring em indoors but if not you can still make do with outdoors, yea just keep em suported its best you can do. You could try blocking the wind from directly hitting your plants, maybe put other plants around the weed plants, to guard them from wind...

Pests are also a problem, just a couple of pests could wipe out ur plants as they are so small. Maybe put a few slug pelets near by, or some gravle and salt to try n keep the pests n slugs at bay.
