The weather forcast for the next week is not good. Highs in the low 50's and lows in the 30's. I am not worried about freezing, just when the sun does not shine for that long, my heat sink stops working. The huge stone wall behind the plot has what is called "thermal enerita" meaning it is so massive that it does not heat or cool fast. This moderates the extrems of temp.,but evens out over time. With average temps in the 40's, given a week and no sun to store heat from, the temps go down. As muddy said if the soil temps get to low, growth stops. However, once this system passes and the sun returns the heat retention will start up again. I need one more month to finish seed production and feel I will get it. Hopefully! I have left one of the old photos, a pure sativa, out still. I think I will let the frost kill her when ever that might be. I am impressed with the growers from UDG who grow outside so far north. They mainly grow photos with a early finishing date. For next year I am going to see if here in the lower lats., if they will get much bigger than even what they get up north. Should hopefully.
