it's going to be a while before they're ripe. if they are quality strains then i'd build a shelter to keep them warm during the frosts. i have one over my haze plants now (recent pics of the frame are in the pic section) and it doesn't take much...in my case i used a 'cabana' frame (tent-type structure for camping/the beach) but any 2 x 4 frame will work, or even take the top off of a table. cover with plastic sheets and voilla...instant greenhouse! (well, sorta kinda instant). it'll cover ya for the lighter freezes as is but if it's dropping below 25-28F, i'd add a space heater too.

but judging by the pics i'd say at least another 2-3 weeks...
