The mold can be a crippling hit to the crop of a grower, possibly destroying it. Without any potent mold tolerant strains, growing marijuana in wet, humid climates is a problem. The best mold resilient marijuana seeds develop as a solid and sturdy plant that could finish flowering outdoors and withstand any harsh conditions. You will often prevent mold formation in some instances, but you need to maintain humidity if you are developing strains that prefer a humid climate. You may want to try strains that are naturally immune to molds for novice growers that are just having the hang of things.

What are Bud Molds?

 Mold is a multicellular organism that typically evaporates dead organisms, while live species, such as various plants and animals, may also be impacted. For farmers, particularly those struggling with moist conditions with little or no ventilation, mold can be a significant concern. Marijuana molds will secretly reveal their own; maybe the first indication that it occurs would be a minor leaf discoloration on the colas or a part of marijuana bud that appears somewhat off-color. You will notice rot in your bud, creeping from the inside, through closer examination. Molds typically take the shape of white fuzz on flowers and leaves, and for farmers who might have been midway across planting a formerly excellent crop, it is a disastrous sight. Both indoors and outside, mold is widespread. In mild, humid climates, it usually happens. Humidity may keep water from being evaporated, which is what contributes to decay. Consequently, in outdoor growing with a moist atmosphere, or even in greenhouses with inadequate water and lighting circulation, mold may occur.

Effects of the Mold on Marijuana Plants 

During the early stage of development, one of the most troubling effects of mold contact on the output of marijuana occurs. Seeds are vulnerable to a mechanism called damping down, which can kill a significant proportion of a crop until it has a chance of being off the field. The damping-off is caused by exposure to gray fungal growth.

Whenever a seedling is impaired by damping away, a solid, vigorous stem fails to develop. Fungi invade the roots and stem, stopping the whole plant from passing upward with nutrients. A gentle, soggy branch and seedlings that protrude over provide indicators of damping-off. It can seem like overwatering in the early phases, but lesions quickly begin to develop on the plant stem. Unfortunately, nothing can save seedlings at this point, so farmers will have to start over it and assume that airborne fungi have not permeated the fresh soil.

The results of exposure to mold in mature plants can include the disease of a plant’s branches, leaves, roots, and buds. Any form of fungus induces a subtly different issue. However, growers can usually check for some lesions or stains on plants in general. The signs of mold damage can be defects on stems and leaves and leaf spots. When introduced to mold and mildew, infected leaves often give off a stinky or rotting scent.

Preventing Molds

The trick to beating mold is to provide safe plants and supply them with the best security to do the job of growing a successful harvest for you! The leading causes of marijuana mold are excessive temperature, soil moisture, and inadequate air circulation. Therefore, be sure that the plants have adequate room over them to have sufficient drainage and exposure to the sunlight, and make sure that moisture concerns are handled.

In the greenhouse, this involves opening vents or, if necessary, installing air ventilation. The actual barrier for outdoor plants is to protect them from being soaked in the mud, so keep an eye on the weather forecasts! Possible options are to bring the seedlings plants indoors or cover the crop.

10 Best Mold Resistant Strains

Super Silver Haze

Super Silver Haze is a popular award-winning Sativa blend derived from the classic marijuana strains Northern Lights, Skunk. Also, Haze, awarded by industrial growers and connoisseurs, respectively. The plants get very tall and unwieldy if permitted to become a suitable outdoor marijuana strain for hot countries. Indoor growers are recommended to use SCROG or LST to monitor height in conjunction with a brief veg period. Super Silver Haze provides farmers with giant colas, so big they can need staking after a long growing cycle of 10-11 weeks. It is immune to mold and other marijuana issues.

White Widow

White Widow is one of the most famous, iconic marijuana strains of all time, perhaps. Its robust genetics, likable natural results, and increasing characteristics are among the most widely used strains for making new strains. Growing is a beautiful strain, and it would be an excellent complement to your greenhouse. It is possible to produce White Widow through seeds or clones. It is a mold-resistant strain, making it a good choice for outdoor cultivation — but it grows well in an almost Mediterranean setting with steady temperatures between 70 to 80° Fahrenheit. White Widow appears even more indica mostly during the vegetative process, despite a mainly Sativa high: plants become bushy and broad and seldom reach 6 feet tall. When grown indoors, the plants bloom in 9 weeks and are prepared for harvest in early October if developed outdoors. Growers should estimate about 37 to 55 grams of the plant to be produced per sq foot.

Original Skunk

The Original Skunk lives up to its reputation, a pungent crop that’s evident from kilometers away and has a THC content level of 15%. The original Skunk standard seeds’ peculiar features and remarkable impacts are favored and loved by buyers and farmers. This plant could yields as much as 250g outdoors, and when grown indoors, the figure becomes 400g. These numbers might not be as big as those of many strains, but you will be surprised when you see the first few Initial Skunk buds. Everyone is a fat, frosty, golf ball-like bud that stinks of wonderfulness, rich in resin. No matter who you call for, even without good old Original Skunk, no growing room or greenhouse is complete.

Green Crack

Green Crack offers a highly energetic body that promises to get you out for more. Citrusy sweetness with touches of spice and lemon, with that kind of smooth, spacious strain, it went a somewhat big step. This robust crop is rapidly growing and sometimes needs trimming. Expect fast growth, high yields, and flowers that will mature in 9-10 weeks. More than 21 percent of this strain’s THC content is solid and is sensed primarily from a full-body high. It is reasonably easy to develop Green Crack, which is versatile enough to acquire outdoors and indoors. However, it can spread a little further when grown outdoors. When growing Green Crack, it is advised to maintain the humidity down when creating Green Crack. Ideally, it should be planted in a mild summer, Mediterranean environment when grown outdoors.

Amnesia Haze

This Sativa-dominant beauty is quick to moderate to develop and can flourish both indoors and outdoors, taking 8-9 weeks to bloom fully. Both growers and customers have been enjoying this excellent strain for a long time. The THC content of this Spanish marijuana strain, estimated at 15.50 percent, is a modest level. Still, the mixture of a higher CBD content level of 1.21% allows the buzz of Amnesia Haze something to relish. In smell and taste, this plant is dank, with an enticing yield as well. This auto-flower from Amnesia Haze will send you up to 150g worth of tasty, thick flowers when grown outdoors. This strain will yield up to 250g when cultivated indoors.

It is straightforward to grow because it’s resistant to molds and other plant diseases. 


You can produce this plant indoors or outside and flowers in only eight weeks, also known as a simple plant to develop. The potent smell of this plant alone is almost adequate to knock you unconscious and send you a crazy ride of the mind. Trainwreck has a solid tolerance for rodents, mold, mildew, and pathogens of daily life. This vigorous marijuana plant can develop both indoor and outdoor environments. However, the Trainwreck marijuana typically takes longer to develop and then harvest while held outdoors. 

Durban Poison

Durban Poison is renowned for producing the same intensely psychedelic impacts as its parent. Considering the massive THC content of this marijuana variety, which could go up to even more than 20 percent, that is not shocking at all. Apart from psychedelic symptoms, a euphoric high can be expected due to smoking this strain. 

This strain is very robust, mold-resistant, and can withstand any harsh conditions so that you can cultivate it both outdoors and indoors. Durban Poison will increase to lofty heights as a Sativa; it can cross a wobbly seven foot! If you have a tall greenhouse with ample capacity, the best choice for this strain could be outdoors. It can be cultivated both indoors and out, and its buds are often fat and heavy and covered with sparkling trichomes in thick layers. That is enough to make you gush because of the sight of its wide glands kindly bursting with resin. Durban Poison will produce up to 350g if cultivated outdoors. The number can fire up to 550g indoors.

Because of its legacy of being a pure landrace with its natural habitat, there is no human activity. Then Sweet Tooth will be up your alley if you are searching for a delicious strain with a respectable big; as a plus, it’s indeed mold-resistant

Afghan Kush Feminized

Afghan Kush is among the best varieties for meditation and sleeps, fresh but still with a tinge of old-school vibe. It is renowned for its potent THC content and stable properties that are components of all Kush derivatives. It is for first-time and new farmers, as it can grow with impressive results quickly everywhere. This plant is a feminized form of seed, with a 14 to 19 percent level of THC material.
