M-39 Cannabis Seeds Feminized
M-39 voted by High Times one of the top 10 Canadian Strains of All Time. Released by one of the oldest, now retired seed banks in Holland. The M-39 was introduced as a production of an extraordinary plant from the very beginning. To this day, this heavyweight, Indica-dominant genetics and true ease of growth made this hardy strain a staple for Canadian growers from Quebec to Ontario and beyond.
M-39 clones easily grow incredibly quickly with good branching and finish with an easy-to-trim profile. It is discreet, low to the ground, and promises a fast harvest. Also, M-39 grows perfectly through the shorter seasons and harsher conditions of northern territories.
Growers may beware of imitations. The buds are known as “Blasters” are often poorly grown-out versions of M-39 or even pretenders mislabeled as M-39. The real deal has that old-school flavor and clean high that is familiar to growers and smokers of a certain age.
Participants may want to gear up for a social night with extra soda pops or juices to support a free-flowing conversation with friends that may end with the necessity for a power nap. This strain is an F2, so expect to get 3 different phenotype. 1. will be a skunk 2. northern lights and 3. M-39 this is great for people that do phenotype hunting.

M 39 is a VERY stout plant. It can take any climate as far as I can tell. If you’re old enough to say that the shop weed is not as good as what we got in the 80’s and can’t find anything that is. This is. If you grow this 48” plant and grow it out right. You will hear the same comments I have. It’s way way better than most strains. It’s about the only old school Dutch seed out there that will take you back and allow you to show others what you were telling them about. The green bud you got back in the day. It’s a pain to harvest. It’s yield is low. If you do grow it you’ll have something spectacular. This is the “Mean Green”. It was 94 F the day I cut em down here. It may respond better in higher temps potency wise. Given the breaded I kinda doubt it. This is the best end product I have found anywhere. I’m 57 years old. Get after it old timers. Happy growing everyone!
