Hey op,

I grow here in Colorado, we get crazy extreme temps and weather conditions, these guys handle

it like champs.  A couple of things for you to consider...

My guys love water.  Everyday in the summer and very heavy every 3-5 days. 

I put everyone in a greenhouse when winter rolls around...it can get down to 0 or less and these guys do just fine, granted, I do get nervous at about 25 degrees, and put a space heater out.  But as long as they don't get snow on em...they do really well.

If you are going to overwinter them, keep them somewhere with little light, no more than 40 degrees and don't water them all winter.  They will be fine with no water, they just go dormant.

Happy growin!
