The Iranian short season is NOT an auto flowering plant. It is only MORE photo-sensitive then most plants. That means, as soon as you change the light cycle down, it starts budding. I have 5 in the ground, i put them out when they were 4 nodes tall(may21), and right now they are still short in height, but large main colas very fat and sticky.
If i had vegged them indoors for a longer period of time(24hr lights), i could have chosen how much i wanted to harvest in the end. If I had vegged over 3 feet tall, and then plant outdoor, I could get 4+ ounces each plant.
