I grew out his iranian haze two summers in a row outdoors in BC. It was always killer smoke and went a little later than our summer will allow so both times I had to cut it down early and use the early buds. I tried growing iranian auto flower when I lived in australia but I only harvested two small plants. Weed was okay but not as good as his iranian haze in my opinion. Oh I found the iranian haze to be uniform when growing out a bunch of them. I was a newbie outdoor grower both times and have a lot to learn so part of the equation was also my growing skills.
