I've got a Black Domaic X Super Skunk, Black Domaic X G13, White Widow X Big Bud, and two Pineapple that have been out side for the last week. They are all doning good so far. It has gotten as low as 34, but stay's in the low 40's and 50's most of the time. I will let you know if they are still doing good are not in February, when it starts to warm up. I do cover them up at night, when it gets below 40. Other wise I just let them be. Good luck, and happying growing.
