Mold can be a major problem for casual and cash-crop outdoor growers in humid and/or moist climates. Fortunately, there are many mold-resistant strains available to combat this issue. Using a best mold-resistant strain means growers no longer have to worry so much about getting mushy buds, black bud rot, and blue-grey mold which can all negatively affect crop yields.
When looking for a mold-resistant strain, remember that there are several varieties available that have been grown in wet and humid conditions for generations. These strains have adapted to this environment and can thrive in climates that cause major issues for other strains. These hardy, wet-resistant strains were available for purchase in both regular and feminized seeds as late as 2018.
Two strains in particular, Landrace and hybrids, each offer several varieties, all of which are resistant to wet climates and mold.
For multiple generations, landrace strains of marijuana have been grown in the wet climates of South and Central America, Southeast Asia, and parts of Africa. Many popular strains of landrace exist: Thai Sativa, Vietnam Black, Panama Red, and Afghan Kush, just to name a few. The key factors in landrace genetics are mold resistance, hardiness, genetic stability, and resistance to pests and diseases, making them an excellent choice for both growing and for breeding programs.
When looking for a mold-resistant strain, Colombian Gold is a sure winner. All modern cannabis owes its existence to this strain. Colombian Gold has its origins in high-elevation harsh weather conditions. It is a mold and pest-resistant strain and harvest yield is high.
Along with mold-resistance, fast flowering time and outdoor resistance make Durban Poison, a never-hybridized Sativa, a popular choice for growers. This plant does extremely well outdoors even in lousy weather. This strain’s rapid flowering time of 8-9 weeks, resistance to mold and disease, and large buds add to its popularity.
While the massive buds and amazingly-huge trees make this strain appealing, the long flowering time, with some not ending until January, is problematic for some growers. Thai Sativa is a good pick for a mold-resistant strain and having the patience to wait out the flowering cycle is well worth it when it comes to harvest time.
Almost all popular strains of modern cannabis are hybrids, a combination of two plants with different genetics. To find a mold-resistant strain among the hybrids, consider the mold resistance and climate tolerance of the parent plants. Finding a hybrid with a wet-climate and mold-resistant landrace parent is probably the best option. Many times the hybrids outperform the parent plants in terms of growth rate, production, and hardiness, as well.
Super Silver Haze
While this strain has a longer flowering time, its mold resistance and big, heavy bud yields makes it popular. Huge bud growth can be encouraged by adding nutrients to the soil.
Power Plant is a great option for cash croppers. This mold resistant strain has a short flowering time and yields hardy plants with massive buds.
Popular for its sweet, fruity taste, this hybrid is amazingly productive in bad weather. Plants grown outdoors are large and sturdy. Yield is plentiful and can be increased with the addition of extra lighting. Even with days of rain, Strawberry Cough is definitely one of the best mold-resistant strains.
Rainy Climate Doesn’t Mean Moldy Bud
Many options for mold-resistant strains are available for any grower living in a wet, humid, and/or rainy climate. Whether it’s a hybrid or landrace, casual growers and cash croppers alike are sure to achieve amazing results with these cannabis strains.
