Top 5 Mould-Resistant Strains

Cultivating cannabis is an incredibly rewarding process, and smoking your own flowers come harvest is a memory you won’t soon forget. However, as enjoyable as it is, growing weed isn’t without its challenges. There are many hurdles growers have to overcome, and various threats to ward off as buds make their way to the jar. One of these potential threats is mould, a fungal infestation that can strike both during the growth cycle, and after harvest.

There are multiple environmental factors that growers can regulate to prevent the occurrence of mould. Proper watering cycles, humidity, and airflow all play major roles in mould-prevention. To reduce the threat of an infestation taking hold from the get-go, numerous strains have been developed to be highly resistant to mould formation. These strains make great candidates for beginners unfamiliar with accurate plant care, as well as those growing in less than ideal environments.

These 5 strains have been bred to maintain a high resistance to mould:

1. NYC DIESEL AUTOFLOWERING

NYC Diesel Autoflowering features hardy genetics formed by breeding NYC Diesel with a robust ruderalis strain. This sativa-dominant lady is capable of not only surviving, but thriving in a wide range of environments that would otherwise reduce the yield of most varieties. Her natural defences make her highly resistant to fungal and mould infestations, a forgiving trait that leaves room for human error and climatic fluctuations. These dark green and dense buds harbour a THC content of 15% and provide an energetic and euphoric effect that complements coffee breaks throughout the day. Smoking these flowers leaves a pungent yet pleasant taste of bitterness and lemon on the tongue.

This autoflowering variety is easy to grow and will emerge from seed into fully flowered specimen in as little as 55 days. She maintains a small and compact size in any growing environment, which makes her ideal for those looking to keep a low profile. Indoor plants reach up to 90cm in height and produce yields of up to 350g/m². Plants grown outdoors reach between 50–100cm and produce yields of 75–120g/plant.

2. SUPER SILVER HAZE

Super Silver Haze is a worldwide classic that achieved popularity within the famous coffeeshops of Amsterdam. This sativa-dominant powerhouse produces THC levels of around 21%, a factor that contributes toward its immense success within High Times Cannabis Cup competitions. The child of superstar parent strains Haze, Skunk, and Northern Lights, the high immediately lifts the mood and blasts the mind into the stratosphere for hours. These large and bushy flowers are highly resistant to mould and produce a terpene profile defined by notes of sweetness, spice, and citrus.

Super Silver Haze is a highly productive strain both indoors and outdoors. Indoor plants grow to heights of between 80–110cm and produce immense yields of up to 700g/m². Plants grown outdoors surge to heights of 230cm and produce rewarding yields of 550–650g/plant. These flowers will be ready to trim and dry after 65 days of bloom.

3. POWER PLANT XL

Power Plant XL stems from mould-resistant genetics that were stumbled upon by Dutch growers during a trip to South Africa in the 1990s. Zambeza harnessed the genetics of this South African sativa with the goal of increasing yields and ramping up the potency to new heights. The end result of this breeding project was a sativa-dominant beast with a THC level of 20% and a powerful, uplifting, and euphoric high that is designed to augment daily tasks and activities. Each hit is accompanied by tantalising tastes and aromas of sweetness, sour, and pine.

The hardy landrace genetics within Power Plant XL make her easy to grow in a range of environments. Plants cultivated indoors are capable of producing immense yields within small spaces. They’ll grow to heights of between 80–110cm, yet produce hauls of 600–750g/m². Plants grown outdoors reach up to 200cm and produce bountiful yields of up to 600g/plant.

4. WHITE WIDOW HAZE

White Widow is a strain known across the planet for her psychoactive potency and happy highs. An ambitious group of breeders made it their mission to enhance these traits by crossing this formidable lady with premium Haze genetics. The result was White Widow Haze, a sativa-dominant, mould-resistant variety loaded with fruity, tropical, and sugary terpenes. This mesmerising flavour profile makes White Widow Haze an excellent addition to many edibles recipes.

White Widow Haze will be ready to harvest after a flowering period of approximately 65 days. When grown indoors under adequate lighting, this lady will achieve heights of 80–110cm and offer satisfying yields of 500–550g/m². Plants grown outdoors are capable of producing yields of up to 700g each, and can peak at enormous heights of 300cm.

5. NORTHERN LIGHTS XL

Accidental overwatering and overly humid environments are really no match for Northern Lights XL. Her resilient genetic profile makes her resistant to lingering mould spores looking to set up a colony upon her leaves and flowers. This heavy-yielding indica hybrid is usually able to repel such attempts with little hardship. A cross between Northern Lights and Afghani, this strain induces a powerful and physical body stone that makes the muscles feel as though they have just received a deep tissue massage. Her relaxing and therapeutic properties are best experienced during the evening and nighttime hours. A THC level of 19% and tastes of sweetness and citrus also make her a good addition to borderline-psychedelic edibles.

Northern Lights XL is able to produce enormous yields of 600–750g/m² indoors whilst growing to heights of between 120–150cm. Plants grown outdoors under the sun reach taller heights of up to 230cm and max out at yields of 650g/plant. Expect to harvest Northern Lights XL after a flowering period of 60 days.
