Indoor growers can control the vegetation and flowering cycles, so they could do quick harvests can even do these 2-3 months grows but they would be at the expense of less yield, so not sure if they would really do these quick harvests, its not like their is a shortage of product overseas, so no rush to get it out the door with short grows, thats why im a little skeptical if any companies actually do this, as its a lot more work for less yield, when they could just grow the plant bigger in the vegetation cycle and get the same yield as 2-3 of these quick cycles.

Outdoor grows its one grow a year based on the sun for Australia (the Australian grow season runs from August through April (give or take a few months, depending on your specific location and situation) but you can grow autoflowers all year long, maybe your mates are using autoflowers, again though its much lower yields (talking around 30-50 grams for a autoflower plant vs 300-500 for outdoor, so one outdoor grow in season is equivalent to 10 autogrow cycles.)
