Ahh.... 50 degrees ain't nothing but a thing. I live about as far north in the USA as you can get, and deal with cold alot. That IS NOT cold !! We have been having nites in the 30's, and even had two nites of 30 degrees, but no frost. Mine are doing awesome, and only one to two weeks to go. These plants are incredible tough. 50's is our current highs for the day. More warmth to come, for a nice Indian summer !! You had better already have the bud size now, otherwise, YOU'RE LATE !!
