In addition, many commercially bred cannabis strains are not sufficiently adapted to the wet, cold climatic conditions they are often grown under outdoors. This genetic adaptation is a process which, depending upon climate and variety, progresses gradually and takes many years, if not decades, to complete. The result can be a variety that resembles hemp grown for fibre more than it does it’s psychoactive sisters. Humans must therefore intervene in this process and control it to prevent wild adaptation and to avoid the steady reduction of medically valuable and psychoactive cannabinoids. The genetic makeup of a variety therefore calls for compromise. Somewhat less resin or yield can already be significant enough to better equip a strain against mold under critical environmental conditions – especially outdoor. Long-term and comprehensive cultivation tests facilitate the search for the perfect pairing of parental lines or strains. Careful, patient adaptation of new hybrids or pure strains can change the way they respond to new environmental conditions. Years of observation have led us to the conclusion that induced resistance is also possible towards extreme temperature fluctuations and other environmental factors. The use of landrace genetics is another way to strengthen plant defences.
The genetics of the plant genus Cannabis sativa/indica essentially contributes to the risk of Botrytis and other forms of mold. Any plant or animal species should be cultivated and maintained according to it’s natural habitat. An orchid thrives just as poorly in the desert, as a cactus in a tropical rain forest. But we expect from cannabis botanical wonders: that it grows in almost all latitudes of the world, or even in a PC case with a feeble light source, and remains healthy and flowers wonderfully throughout. In the long-term even this does not satisfy all expectations: modern varieties of cannabis must produce more and more resin (THC), be as high yielding as possible, but also grow absolutely homogeneous.

Each strain not specifically bred for northern regions should only be grown in a greenhouse with some form of climate control to prevent excessive humidity and cold – provided that it is recommended for your climate in the detailed world map of the Outdoor Guide in the first place. Growers in difficult northern climates have to accept that there are only very limited choices on the cannabis seed market for truly reliable and early strains: such as Mandala #1. Even then, freak weather patterns from global warming can always threaten your crop and case unforeseen damage. Nature itself remains the ultimate force.
According to the latest scientific research the ability for humans to grow very old in good health boils down to only 20-40% of our genetic make-up. The remaining 60-80% are influenced by environmental factors: how we live and where we live. When we look at the plant world it is not much different. How we care for a plant, and to what environment we subject it to, creates the biggest impact on quality and yield (synonymous for a healthy life). As breeders it is our responsibility to ensure that the genetic base is as strong as it can be to support your efforts in proper gardening. But the primary step in preventing diseases such as bud mold is for you to also choose the right strain for your environment and cultivation style.

In our breeding projects at Mandala Seeds the immune system and resistance of a strain belongs to one of the high priorities. We use several methods to ensure this trait is contained or enhanced in the Mandala strains:
* Mold and pest resistance is subject to a suitable environment for each cannabis variety. Cannabis that is genetically conditioned or adapted to a specific climate must be grown under these conditions for best results.

Bud mold

Remove all affected buds immediately – Carefully remove and discard all buds with bud rot, as well as nearby buds – this is incredibly important if you don’t want to lose the whole harvest! Don’t let anything any of the rot touch other parts of your plant, as it can further spread mold spores.

How to Control Bud Rot (these are most important!)
If you can’t fix the environment, I highly recommend cutting your losses at this point. If you know that it’s still going to be cool, humid or wet for your plants, it’s recommended you harvest immediately to prevent further buds from becoming infected. Buds harvested early are better than moldy buds!

Cannabis bud rot is caused by a type of fungus known as Botrytis cinerea.
Any part of the cannabis plant affected by bud rot should be discarded immediately! This helps prevent further infection and all buds touched by this toxic fungus should never be smoked or used.
If your plants are never exposed to these spores, they will never get bud rot.
Good air movement – Create good air circulation and make sure there’s always plenty of air moving over all the buds and leaves. Make sure your plants are getting access to cool, fresh air.
If you already have bud rot and can’t fix your environment (which is the best way to kill Botrytis), I highly recommend cutting your losses and taking down the plant.

The deadened spots usually stand out and catch people’s attention, even if growers don’t know what’s wrong, they often instinctively know that something is wrong since the spots don’t look like the rest of the buds on the plant.

Bud rot is a mold that develops in the thickest parts of cannabis buds. Read for more information on how to prevent and solve bud rot before spreading!
