Anyone know when flowering starts in CO

Hello out there looking for a little help I popped 2 durban poison plants in the ground inside our greenhouse about what time on average do plants start flowering here in Colorado

From what i have been told, and am basing this year on, is they will start anywhere from (late) july to august. So at this point you could be looking at 2 months of veg before they start to flower, do the math and you can see how quickly you push up on november with longer flowering strains.
Please correct me if i am wrong guys.

Yep- what he said!! Entire Northern Hemesphere, bloom starts late july into early August regardless of weather... Sativas may be a little later, but not always!

Small update not sure why but the durban poison seems to have started flowering my backyard was pretty illumintated so I have been leaving the porch light off seems to have started flowering I'm not to happy about this as I was hoping for a longer veg period any input would be good

Water regularly? The light cycle is everything to this plant, turn the lights on at night to delay the start of flowering.
