Thank you. I have always been interested in Mexican brick weed.
There is a great thread on IC called “siembra de chonga” by a member named “Sinaloa”. He has sent his seeds to the guys at Cannabiogen and they resell them. He is a commercial grower way up in the hills in Mexico. His thread is very interesting and informative.
He explains that the growers have switched to short flowering plants and that they try to get a crop out from seed to harvest in just a couple of months due to eradication efforts by the military. He says very few people there are interested in Sativas.
In the last twenty years there has certainly been a genetic shift from the old predominantly sativa plants, to a shorter and faster Indica dominant type plants which are more common now.
