if you could throw them in to a tent or closet you'd have a lot more control over the timing of everything.. you could initiate flowering tomorrow.. and have better success (harvest) with a more consistently timed lighting schedule, oustide is risky because of pests as well.. if you planted in the ground just stick with it,
if you went in pots, i'd totally recommend going inside for flowering, esp so that you can lower temperatures towards the later part of flowering
