Lineage Yumbolt Autoflower
Yumbolt Auto comes from crossing Yumbolt and Lowryder 2. It is a mostly Indica autoflowering strain (80% Indica / 20% Sativa) that tends to show a berry, earthy and sweet flavor with a strong, indica-leaning body high, along with calming, relaxed and sleepy effects.
Origin
The Yumbolt Auto strain traces its origins to the legendary Humboldt County in California, a region famous for iconic strains like San Fernando Valley Kush and California Hash Plant. This autoflowering variety crosses the classic Yumbolt with Lowryder 2, crafted to deliver the ease and speed of modern autoflowers.
Although the finer details of its heritage are debated, Yumbolt has long been known for its resilience and potency. Yumbolt Autoflower seeds are perfect for growers who want the mystique of California genetics with the convenience of autoflowering technology.
Yumbolt Auto Seeds Sativa or Indica?
The Yumbolt Auto strain is predominantly Indica (80% Indica / 20% Sativa), delivering classic indica traits such as compact growth, dense buds and deeply relaxing effects. That indica dominance makes it ideal for anyone seeking soothing body relaxation.
Growers appreciate its sturdy structure and adaptability to different environments. Yumbolt Auto seeds thrive both indoors and outdoors, offering reliable results and quality harvests with minimal effort.
Yumbolt Auto Effects
The Yumbolt Auto strain provides the deeply relaxing effects typical of indica-dominant varieties. Users often experience a calming, sleepy body high, which makes it an excellent choice for stress relief and sleep support.
A subtle cerebral touch keeps the mind pleasantly clear before the calm takes over.
Yumbolt Auto Flowering Time
The Yumbolt Auto strain has a short life cycle of 8 to 10 weeks, making it a great choice for growers who want quick results without compromising quality. Its Ruderalis genetics simplify the whole cultivation process.
These autoflowering seeds consistently deliver dense, resinous buds in a short timeframe, perfect for growers on tight schedules. Yumbolt Autoflower seeds ensure a rewarding harvest that combines speed, potency and exceptional flavor.
How To Grow Yumbolt Autoflower?
Yumbolt Autoflower seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development. Although they are compact, robust and moderately easy to grow, we should always prevent any pests.
You can use different growing methods to retain and enhance the terpenes and flavors of your Yumbolt Auto buds.
- Use a quality substrate. Perlite, peat or coco coir are ideal for moisture retention.
- Thanks to the experience of our customers with our Yumbolt Autoflower seeds, we know that we can increase yields by up to 20%.
Autoflowering seeds are very popular among growers. They are known for their fast life cycle and their ability to flower automatically after a set period of time, rather than relying on changes in the light cycle like other cannabis strains.
As for light, autoflowering seeds can grow and flower with as little as 12 hours of light per day, and they do not need a specific light change to move from the vegetative to the flowering stage. We recommend an 18/6 or 20/4 schedule to obtain the best possible yields.
This gives growers greater control over the process and lets them create an optimal environment without having to worry about light timing.
Even so, it is important that the plants receive enough light for healthy growth, as the quality and quantity of light affect both yield and development. Another advantage of autoflowering seeds is their fast life cycle.
These plants can grow and flower in as little as 8-10 weeks, which means several harvests a year. Autoflowering plants also tend to be smaller and more compact, making them ideal for small spaces or indoor grows.
As for quality, keep in mind that genetics and growing conditions play a big role, and many autoflowering strains have won awards for their taste, aroma and effects, proving they can produce high-quality marijuana.
Remember that our plants also need good nutrients as seedlings, in their vegetative period and finally in their flowering period.
When you grow outdoors, choose the best date for your crop and a place where the plants receive the most hours of sunshine. If you prefer to grow indoors, use good tents, textile pots, led lighting, an air extractor to circulate clean air and, of course, a good carbon filter to avoid problems with neighbors or the law.
Keep daytime temperatures between 68-80 ℉ and nighttime temperatures 7 to 9 ℉ cooler than the day.
Autoflower plants need low humidity to thrive. Keep relative humidity (RH) at 55%-60% during the vegetative phase, reduce it to around 40% during flowering and to about 30% by harvest.
Outdoors, in the Northern Hemisphere growers should sow their autoflowering seeds in April, achieving a first harvest in mid summer and a second between July and mid October. Healthy Yumbolt Autoflower seeds produce about 3 – 4 oz/plant | 100 – 120 gr/plant of buds each.
Indoors, these crops have a quick cycle of 8 – 10 weeks and produce about 1.31 oz/ft² | 400 gr/m².
Ideal Climate for Growing
Yumbolt Auto is best suited for a warm temperate climate, where the summer months provide long hours of sunlight and moderate humidity. The ideal temperature range is 70-80 ℉ (21-27 ℃), which promotes robust growth and potent yields and lets the plants reach their full potential. It adapts to varying elevations but flourishes at lower altitudes where sunlight is more consistent, and well-draining soil is essential to avoid excess moisture.
In the United States, states with especially favorable climates include California, Oregon, Colorado, Washington, Arizona, Nevada and Florida, which offer the warm temperatures and abundant sunlight this strain thrives on. Areas with moderate rainfall also help support healthy development. By choosing the right location and keeping an eye on temperature and humidity, growers can create an optimal environment and bring out Yumbolt Auto’s best attributes.
What Does the Strain Smell Like?
The buds of Yumbolt Auto are rock hard, soaked in resin and carry a crystalline sheen from the sheer amount of trichomes. Its taste and flavor are a blend of berry, earthy and sweet notes.
Yumbolt Auto makes a delicious, smooth smoke and delivers a strong, relaxing experience. Thanks to its large resin production, it is an ideal strain for high quality extracts and concentrates.
