Growing marijuana in a wet humid climate is a completely different ballgame than what most growers face. Still, finishing quality buds in the pouring rain is not impossible if you are selective, careful and attentive.

 

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 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 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.

How so?

I’m here to tell you to 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 Strains

 

Landrace strains

 
A landrace is a cannabis strain bred in an area exclusively for many generations, never crossed with another variety. Inbred, the marijuana has acclimated to the local environment, and proves to be stable, uniform genetics.

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

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.

These landraces originating from the wet areas of the word will often possess the traits you are looking for. Mold resistance, vigor, hardiness, resistance to common pests and diseases, and genetic stability just to name a few.

 Durban Poison

 

Durban Poison is a 100% sativa inbred, never hybridized landrace originating from South Africa. An strong hardy 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. You can get Durban Poison huge outdoors and reap wonderful fat bud harvests, even in awful weather. This strain 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, quite enjoyable. Fast flowering time, high yields and outdoor resilience equals prime outdoor cash-cropper.

 Brazil Amazonia

 

Your search for a mold resistant indica is over. This variety is a pure indica strain collected from the Amazon rainforest. Buds are rock hard and dense, with a citrusy smell and flavor. Brazil Amazonia finishes very quickly and stacks up fat. When vegged under lights she will finish before 8 weeks. Big yields for all kinds of growers, indoors and outdoors. A vigorous, fast growing strain that performs well in clone rotation set-ups. I have done successful, top quality guerilla grow operations with clones of this strain. Mold resistant and easily marketable, Brazil Amazonia is a true performer.

Colombian Gold

 

Colombian 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 originating from Colombian Gold as well as countless others. A tall and mighty plant, she comes from a high elevation and can handle harsh weather with strength. Mold and pest resistant. This variety was used by Simon Bolivar as he traveled around the Amazon rainforest trading spices and medicinal plants with natives during his conquests. Musky and citrusy, Colombian Gold is a very enjoyable smell and smoke. A natural big grower and yielder, don’t be surprised harvesting multi-pound plants.

Thai Sativa

 

I have been growing Thai sativa strains longer than any other variety. These plants get larger than any other strain, growing into gigantic trees. Extremely mold resistant and long flowering, growing a Thai pure sativa is not for the faint of heart. Many phenotypes of this strain will not finish flowering until January. Most people who try growing a Thai sativa can not wait that long, for different reasons, and end up harvesting her early – thus giving the strain a false reputation for scrawniness. If finished correctly (which is very difficult for those not in a tropical/sub-tropical climate), she will form up into sweet massive colas that will droop down and require staking. My biggest, heaviest yielding strains ever have been Thai sativas. Her fully finished buds are big, hard and competitive. The smell is unique to SE Asian sativa strains, resembling rotten fruit.

Hybrid strains

 

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

Although the genetics are not stable breeding once a strain is hybridized, it 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 whose parents are mold resistant landrace strains. Solid breeding and hardy, hybrids made from landraces or inbred strains quite often perform better outdoors than the over-hybridized alternatives (although there are exceptions).

Orient Express

 

Orient Express is a mix of the legendary Vietnam Black crossed with a Yunnan Chinese indica. Very high production grown correctly; experience huge buds with a big compact indica bush structure and 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. This hybrid 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 her all the way til the end and you will be rewarded.

Super Silver Haze

 

Originating from classic inbred strains Skunk, Northern Lights and Haze, Super Silver Haze will blow your mind with her massive buds. Plants require staking the buds get so big and heavy. Yields extremely high and grows into giant plants, grow this strain outdoor and be flooded with pot. The price you pay for these fat harvests will be the longer flowering time – but – if you can wait, you will be in for a huge surprise! Performs well resisting mold and disease. Be sure to provide your soil with plenty of nutrients growing Super Silver Haze, in order to pump the maximum bud growth from your monsters. A strong high. Enjoy having loads of beautiful, sweet silver buds with a taste reminiscent of sugar-cane.

Strawberry Cough

 

With mysterious genetic orgins and a taste to die for, Strawberry Cough handles the bad weather surprisingly well. She has held up to guerilla growing in poor, wet conditions in days of rain, much surpassing our expectations for a strain so notoriously grown indoors. The flavor of Strawberry Cough sure lives up to its name. Incredibly sweet, literally tasting just like strawberrys, your friends will be hooked. While not the biggest yielder or grower, with proper care you can get large plants outdoors and produce heavy amounts of bud off each plant. Provide addidtional lighting on an extended vegetative cycle, and you will be supplied with a solid amount of amazingly fruity pot.
