Since Colorado legalised i have been following the rise of Cannabis increasing when Cali and Canada both went legal as well, Youtube is full of grow and info videos with some micro grows in small spaces, there are maybe 100 web sites selling 100's of variety's of seeds, auto flowers, feminised all sorts - its a big industry that is now somewhat unstoppable due to size and the Internets ability to make everything local and easy.
Aust Post and customs are being overwhelmed with imports via the post and they can do little to stop it, seeds in general dont smell like pot so the dogs cant detect them, auto flower feminised seeds only take 3 or 4 months to mature and can be grown in a small suitcase sized area.
