8 Resilient Mold Resistant Cannabis Strains for Wet Climates

Growing marijuana in a wet humid climate is a completely different ballgame than what most herb growers face. Nevertheless, finishing quality buds in the pouring rain is not impossible for the selective, careful and attentive cannabis cultivator.

Wet climates provide a challanging, but possible experience.

Have you ever dealt with pounds of moldy weed?

Plants soaked; buds mushy and trashed, covered with white/blue mold and black bud rot. Only to harvest and bring them inside to further multiply the problem.

Many cannabis growers feel it is impossible to produce buds worth any value in such wet weather. They will be stuck pulling plants well before they are finished flowering, and justify doing so by the bad weather. Early harvesting will produce shrunken yields and scrawny, undeveloped buds that are difficult to market.

Here in Hawaii, we are faced with some of the rainiest, most humid conditions in the world. The town of Hilo, Big Island, Hawaii has an average of 126.72 inches (3,220 mm) of annual rainfall between 1981 and 2010, with with 275 days a year getting rain. It has the most amount of rainy days per year in the northern hemisphere.

Yet, people are producing amazing marijuana outdoors in Hilo, Hawaii.

How so?

It may come to you as a surprise that there are cannabis varieties adapted to wet conditions, and can even thrive in them!

Many types of marijuana have been bred in such humid and rainy environments for generations. Through this, the plants have built up a natural resistance to the climate, in order to make it through their flowering process long enough to mature seed.

Selecting Mold Resistant Strains

Landrace Strains

A landrace is a marijuana strain bred naturally by seed in an area exclusively for many generations, that has not been crossed with another variety. Inbred, the cannabis genetics learn how-to adapt to the local environment, and prove to be stable, relatively uniform genetics for seed breeding.

Landrace plants produced from seed are themed closely similar to each other, and are ideal for breeding programs – often producing solid, vigorous and resilient hybrids when crossed. Some popular examples of landrace strains are: Panama Red, Vietnam Black, Afghan Kush, Morrocan Hash Plant and Thai Sativa.

Wet Climates: What you want to look for in a mold resistant, hardy strain is a genetic background from a wet climate. Parts of SE Asia, South America, Central America, even certain parts of Africa all have wet climates where marijuana has been breeding for many subsequent generations.

Landraces originating from the wet areas of the word will often possess the traits that hold resilient qualities. Mold resistance, vigor, hardiness, resistance to common pests and diseases, and genetic stability are to be found in these treasured genetics.

Durban Poison

 

durban-poison-strain-outdoor

Durban Poison is a 100% sativa inbred, never hybridized landrace originating from South Africa. Strong and hardy seeds and plant, exceptionally resistant to mold and disease. Flowering time is short for a sativa, 8 – 9 weeks  which makes her suitable for all kinds of growers.

Durban Poison gets huge outdoors and reaps wonderful fat bud harvests, even in awful weather. Durban has been around since the 70’s and still competes in today’s market with her high quality buds.

Smells and tastes like a minty herbal spice, a Durban delicacy. Fast flowering time, impressive yields and outdoor resilience equals prime outdoor cash-cropper.

Colombian Gold

 

colombian-gold-strainColombian Gold is a legendary landrace sativa originating from the Santa Marta mountains of Colombia. This strain is a major foundation of all modern cannabis genetics, the infamous Skunk #1 seeds originating from Colombian Gold as well as countless others.

An original beaster, Colombian Gold comes from a high elevation and can handle harsh weather with strength. Mold and pest resistant. Colombian Gold seeds were used by Simon Bolivar as he traveled around the Amazon rainforest trading spices and medicinal plants with natives during his conquests.

Musky, spicy, fruity – Colombian Gold is a savory smell and smoke. Naturally titanic; don’t be surprised when harvesting multi-pound plants.

Thai Sativa

 

thai-strain-sativa-outdoor-huge

Thai landrace sativas grow larger than nearly any other strain, photosynthesizing into freaky gigantamongus trees. Ultimately mold resistant and long flowering, growing a Thai pure sativa is not for the faint of heart.

Many phenotypes of Thai seeds will not finish flowering until January. The general masses who try growing a Thai sativa can not wait that long (for various reasons), and end up harvesting the plant early – thus giving Thai strains a false reputation for scrawniness.

If finished correctly (which is challenging when outside a tropical/sub-tropical climate), seeds will evolve into arm-sized colas that droop down requiring staking. Thai has the potential to be the all-time heaviest yielding strain. Her fully finished buds are big, hard and competitive. The smell is unique to SE Asian sativa strains, often resembling rotten fruit and anise.

Hybrid Strains

The offspring of two ganja plants with different genetics is called a hybrid.

Although plant genetics are not immediately stable breeding once a strain is hybridized, hybrid strains can have many advantages to the grower:

A hybrid can have the bud qualities of an indica while taking taking the bigger stature of a sativa. Often hybrids have what is called “hybrid vigor” and out-perform both of their predecessors in growth speed and yield while shortening the sativa flowering time.

Hybrids make up most of the genetic stock of cannabis nowadays. Nearly all popular modern strains are hybrid such as: Blue Dream, OG Kush, Diesel, Girl Scout Cookies, Trainwreck, White Widow, ect…

When searching for a suitable hybrid, always look at the parents. For best defense against wet humid climates, find strains that are bred from mold resistant or rainy climate landrace strains.

Well-bred hybrids made from landraces or hardy inbred strains most often perform better outdoors than the over-hybridized alternatives (however, there are some exceptions).

Orient Express

 

orient-express-strain-budOrient Express is a mix of the legendary Vietnam Black crossed with a Yunnan Chinese indica. Soaringly high bud production when grown correctly, experience obese buds on a compact indica bush structure with a shortened flowering time.

Vietnam Black is renowned for it’s incredibly strong psychedelic high – described as extremely intense, even frighteningly mind-bending…the kind of weed you smoke at a party and everybody goes home. Orient Express retains the intensity of the Black, but a little more relaxed with the addition of an indica. Musky floral smell and taste – the smoke is incredibly smooth, easily being able to enjoy BIG hits.

Orient Express will hold up to any weather conditions, mold issues are non-existant, an ideal wet weather strain. The buds are utmost quality grown outdoors as well as indoors, be sure to finish Orient Express all the way til the end for an enchanting Asian surprise.

Super Silver Haze

 

super-silver-haze-strain-plantOriginating from classic inbred strains Skunk, Northern Lights and Haze, growing Super Silver Haze will blow your mind with drooping, colossal flowers – plants require staking the buds get so big and heavy.

Yields exceptionally fruitful and grows into giant plants; grow Super Silver Haze seeds outdoor and be flooded with killer pot. The price you pay for these fat harvests will be the longer flowering time – but – for the wait will be rewards in the form of dankness.

SSH performs well resisting mold and disease. Be sure to provide soil with loads of nutrients while growing Super Silver Haze, in order to pump the maximum bud growth from these monsters. A confusing high. Enjoy having loads of glamorous, sweet silver buds with a taste reminiscent of sugar-cane.

Strawberry Cough

 

strawberry-cough-strain-budWith mysterious genetic origins and a taste to die for, Strawberry Cough handles the bad weather intriguingly well. Strawberry Cough has proven itself through guerrilla growing in poor, wet conditions with days of rain, much surpassing expectations for a strain so notoriously grown indoors.

The flavor of Strawberry Cough most certainly lives up to it’s name. Incredibly sweet, literally tasting just like strawberries, anyone who gets a sample will instantly be hooked.

While not the insane heavy yielder, with proper care Strawberry Cough seeds turn into large plants outdoors, producing ample amounts of bud off each plant. Provide additional lighting on an extended vegetative cycle, and prepare to be supplied with a solid amount of amazingly fruity pot.

    Aloha braddah,
    Much mahalos for this blog. This article and the “Top 10 Mold resistant…” are the kinds of info I’ve been looking for for years. So glad I stumbled into your blog. Well-written and very comprehensive. Keep it coming! Aloha, from leeward Oahu.

      Much Aloha,

      Thanks for enjoying, appreciate the compliments.

      Mahalo, shoots!

    Hey braddah, I get one question maybe u can answer. Besides the mold problem, another one that messes me up is spider mites. U guys don’t have that prob in the BI? I tried using all the stuff the mainland guys talk about on the message boards….all that kind insecticidal soaps from Home Depot and whatevs. Kinda works at first when I spray everyday, but as the plants get bigger, seems like I fighting one losing battle. I’d like a locals perspective on spider mites. Mahalos!

    And one more time: thanks for your blog! Way more fun reading about locals growing. Shoots!

      Not really a problem on the BI. There are various marketed products available for sale, but rubbing alcohol mixed with about 40% water will kill the buggers. Also, if you’ve ever watched the series Trailer Park Boys, they collect ladybugs to put on their plants to combat the spider mites. Aloha!

    Nice work braddah, we need it. Hopefully my high CBD Supreme Durban has kept its mold fighting genetics after the cross.

    Mahalo nui.

    Aloha,

    I live on the leeward side of the big island and wanted to add another strain to your list of strains that grow well here, or in wet climates.

    Kilimanjaro by WOS.

    I never have ever had a mold or mildew problem. Grows well even in lava cinders. Lol

    Malama pono.
