Yeah I was gonna say... NH you shouldn't get a frost until like first week of November. Watch the weather from mid OCt on and you should be fine. You should have no problem with frost before Mid October. If I know its gonna frost forsure I go cut them down but if its iffy you could just throw a bag over each one if you are close by or if they are in pots put them inside for the night but you should be fine in NH anyways, don't fret my friend your girls with be great. Now some of us other guys up more north like Pllantsinpants and I, we really have to look out for frost anywere from Oct 7th on honestly most plants up here can't get to full maturity unless you bag them, bring them in or just use a fast flowering strain.
Best of luck.
