im just worried its gunna get to cold before my girl finishes. thanks guys!!!

You're just going to have to hope for an abnormally late frost.

Overhangs, lath structures and evergreen branches provide nice cover from frost. If you can, move your plants to these sheltered areas.

If plants are in rolling containers, move them indoors during really cold nights.

If your plants are permanent, or too large to be moved, cover them with a cardboard box, sheets, or burlap, but don't allow the material covers to rest on leaves, they will the burn foliage. To keep materials off the plant's foliate, drive stakes in around the plant to create a temporary shelter that the material can be draped over. Remember to remove the covers during the day.

Don't use plastic covers as they can smother a plant.

ok. how far along should they be end of oct? and could i run a 400 watt hps outside and put it on em during the day and have a heater blowing on them at night?

Its not the lack of light during the day, it the lack of heat at night, if you can build a make shit tent over then (not touching pref.) with a heater and monitor the temps you should make it to harvest, I don't know enough about your area to tell you if that strain will grow to its full potentail before yo have to harvest, but i think i can help you get a couple more weeks of grow with my tips!
