Glad you are back. Any thoughts about an Ace Haze type that will finish outdoors near Denver? I am about 40 degrees, but the elevation makes for a shorter grow season.
When are first frosts typically? Firs inclination is the feminized Haze x Kali China. You can go to Ace's website and look on second tabs of each specific strain. It will tell you when flowering outdoors should conclude as well latitude recommendations. Of course, with altitude, most important when you will have first frosts.
