This strain has been around since the 1990s, making it one of the oldest strains still in production today. Yumbolt Autoflower is known for its high THC content, ranging between 18-24%, as well as its low CBD levels (around 0-1%). Noted for its quick flowering time of only 8–9 weeks from seed to harvest, this strain is great for those who want speedy results or need to make space in their grow room quickly!

A Yumbolt Autoflower strain is a type of cannabis seed that automatically transitions from the vegetative stage to the flowering stage without requiring any change in light cycle. This means that it can be grown both indoors and outdoors, with no need for additional lighting equipment or complicated setup processes.

Yumbolt Autoflowering plants are known for their rapid growth rate, making them ideal for those looking to get their harvest quickly. They usually reach maturity within 8-9 weeks of germination and typically produce medium yields of resinous buds coated in trichomes, giving off earthy aromas reminiscent of diesel fuel blended with sweet fruitiness. Its effects tend to lean towards a heavy stone feeling accompanied by an uplifting cerebral buzz that many find helpful when dealing with stress or anxiety levels throughout the day. 

Additionally, this strain may also provide relief from chronic pain conditions such as arthritis and fibromyalgia due to its high THC content (upwards of 24%)


The Yumbolt Autoflower strain is an indica-dominant hybrid that was bred from two classic strains, the original Haze and Afghani. It is a powerful strain with an earthy, sweet taste and aroma. It provides a strong body high while still offering some mental clarity and focus. The effects come on fast, providing full body relaxation that can help relieve pain and stress. The buds are dense, frosty green in color with dark orange hairs throughout.

It has a flowering time of 8-9 weeks, making it one of the fastest autoflowering varieties available today. Yumbolt Autoflowers have good yields for their size, producing between 50 – 200 grams per square meter when grown indoors under optimal conditions. Outdoors, they are even more productive, yielding up to 500g/plant when given plenty of sunlight and nutrients during their growing period.

The THC content in this strain averages around 18% but can reach as high as 24%, giving it a potent psychoactive effect that may not be suitable for novice users or those who are sensitive to THC levels. CBD levels remain low at 0–1%.

Yumbolt Autoflower is known for its tranquilizing effects, which make it ideal for evening use before bedtime or after work when you want to relax without becoming overly sedated or couch locked. Some users experience mild visuals, making it a great strain for creative activities.


The Yumbolt Autoflower strain is a very hardy, easy-to-grow strain that can be grown indoors or outdoors. It thrives best in warm and sunny climates with temperatures between 70° and 85° F (21–29°C). The plants are quite resistant to pests and diseases, making them an ideal choice for beginners.

When growing indoors, the Yumbolt Autoflower strain requires minimal care and attention. This makes it perfect for less experienced growers who don’t have much time to dedicate to their cannabis garden. The plant grows quickly, reaching up to 3 ft (90 cm) tall in as little as 8 weeks from the seedling stage. Indoors, this strain prefers soil or hydroponic systems but also does well when grown aeroponically with an adequate lighting setup such as HID lamps or LED grow lights.

Outdoors, the Yumbolt Autoflower variety should be planted around the beginning of June so that it has time to mature during the summer months before autumn arrives. Plants need at least 6 hours of direct sunlight per day and regular watering every 2-3 days depending on weather conditions; however, make sure not to overwater since these plants don’t do well with soggy roots! 

To ensure optimal growth, you may want to supplement your garden with some additional nutrients like manure tea or liquid fertilizer throughout its flowering cycle, which usually takes 10–12 weeks until harvest time arrives.

Overall, this autoflowering cannabis variety is one of the easiest strains out there both indoor and outdoor cultivation wise due its natural resistance against pests & diseases while providing plenty of buds covered in trichomes containing high THC levels!

This autoflowering variety produces large yields even when grown indoors under artificial lighting systems such as LED lights or HPS lamps. As well as being capable of producing a generous harvest in short periods of time – typically 8 weeks from germination – the crop can be harvested multiple times over the course of one season due to its fast maturation period, which makes it more profitable than some other strains available on the market today.

Finally, Yumbolt Autoflower does not require any special fertilizers or nutrients; instead relying solely on natural sunlight for growth purposes, meaning there’s no need for costly chemicals when growing this particular type of cannabis plant at home—saving both time and money!

  1. Start with seeds from a reputable source: Before beginning your Yumbolt Autoflower strain cultivation, it is important to find a quality seed vendor that can provide you with high-quality seeds. This will ensure that you have the best chance of success when growing this specific strain.
  1. Provide optimal environmental conditions: To ensure healthy growth of the plant and the best yields possible, make sure to maintain an even temperature in the grow room between 68-77°F (20-25°C) and relative humidity levels between 40%-60%. Additionally, make sure to provide plenty of fresh air circulation within your grow space by installing fans or other ventilation systems as needed.
  1. Maintain adequate light exposure: While autoflowers are known for their ability to thrive under less than ideal lighting conditions, providing them with enough light will promote better yields for your plants, so be sure to use LED lights or HPS/MH bulbs if possible. Make sure not to exceed 18 hours of total light per day, however, as too much light can cause stress on the plants, leading to reduced flowering times and lower yields overall.
  1. Feed your plants adequately but don’t overdo it: It’s important that you feed your Yumbolt Autoflower correctly otherwise it won’t reach its full potential harvest size wise nor produce buds of good quality; however be careful not to overfeed either since these strains are often sensitive when it comes down to nutrient intake and excessive amounts may lead to nutrient burn which could negatively impact growth & yield performance.
  1. Harvest at the right time: The Yumbolt Autoflower strain typically finishes flowering within 8-10 weeks, so make sure to pay attention to signs such as color change in pistils or buds and trichome clarity when deciding on when to harvest. Doing this correctly will ensure that you get the best results from your plants!


The Yumbolt Autoflower strain is an indica-dominant strain that produces a powerful and sedating high. This strain is known for its heavy yields, which require plenty of nutrients to grow properly. To ensure your plants receive the nutrition they need, it’s important to provide them with balanced amounts of macronutrients and micronutrients during each stage of growth.

During the vegetative phase, your Yumbolt Autoflower plants should be fed a balanced combination of nitrogen (N), phosphorus (P), and potassium (K). A ratio such as 10-10-5 or 8-8-4 will provide enough nutrients for healthy vegetative growth. Additionally, small amounts of iron, calcium, sulfur, and magnesium are also essential in this stage.

When flowering begins, you can adjust your fertilizer ratios slightly to encourage bud formation; something like 5–7–6 works well here too. In addition to N-P-K fertilizers you may also want to add trace elements like zinc, copper and boron at 1/2 teaspoon per gallon once every two weeks throughout flowering as well as one application right before harvest time if needed.

Finally, it’s important not to overfeed your Yumbolt Autoflower plants when using chemical fertilizers since they can easily burn the roots if given too much at once. Always follow directions carefully when applying any type of nutrient or soil amendment! For organic growers compost tea made from worm castings or other organic materials makes an excellent supplement that won’t harm fragile root systems either way so long as it’s applied correctly according to instructions provided by the manufacturer.

With the right combination of nutrients, your Yumbolt Autoflower plants can produce heavy yields and powerful buds. Taking the time to provide them with balanced nutrition will go a long way towards ensuring successful harvests!


The Yumbolt Autoflower strain is an incredibly popular cannabis strain with a unique flavor and aroma. However, like any other cannabis strain, there are some common problems that can occur when growing it.

First, the Yumbolt Autoflower strain requires a lot of light to grow properly. Without proper lighting, the plants will not produce as much bud as they should and may become stunted in their growth. Additionally, if your grow room is too hot or cold for this particular strain, it can cause issues such as wilting or nutrient deficiencies.

Second, pest infestations can be a major problem when growing the Yumbolt Autoflower strain. Common pests to watch out for include spider mites and aphids, which feed off the buds of your plant’s leaves and stems. To prevent these pests from invading your crop you should regularly inspect your plants and apply insecticides if necessary.

Thirdly, over-fertilizing can also be problematic for this particular variety of cannabis due to its sensitive nature towards nutrients found in commercial fertilizer mixes. If you find that you are using too much fertilizer on your plants, then consider backing down on dosage amounts or switching to an organic soil mix instead.

Finally, when harvesting the Yumbolt Autoflower strains, make sure that you do so at exactly the right time since harvesting too early or too late could lead to lower yields than expected or poorer quality buds overall.


The Yumbolt Autoflower strain is a strong indica-dominant hybrid that is known for its high THC content and unique flavor. This strain is popular among cannabis users who are looking for an intense, long-lasting high with relaxing effects.

Harvesting the Yumbolt Autoflower strain begins when the majority of trichomes on the buds have turned from clear to cloudy or amber in color. The buds should be dry enough to snap off rather than bend when picked. It’s important to make sure all of the leaves around each bud are also dry before harvesting, as these can still contain moisture that could affect curing times later on.

Once harvested, it’s recommended that you hang your buds upside down in a cool, dark location with good air circulation to allow them to continue drying out over several days or even weeks, depending on humidity levels and temperatures in your area. Once dried, trim away any extra leaves and shake off excess pollen glands before storing them in an airtight container such as mason jars or vacuum sealed bags. – this will help preserve their potency and aroma for up to six months if done correctly!

Overall, harvesting the Yumbolt Autoflower strain can be very rewarding due to its potent effects, which makes it great for those seeking deep relaxation throughout their session while enjoying its distinctive flavor profile at the same time!

Learn more about Yumbolt Autoflower Strain

Yumbolt Autoflower is an indica-dominant strain that grows with minimal maintenance. It generally takes around 8 to 10 weeks from the germination of the seeds until harvest time. The vegetative growth stage—when the plant develops leaves and branches— usually lasts for 3 to 4 weeks, depending on the environmental conditions and light cycle it receives. Once this has been completed, the flowering stage begins; during which time buds start forming and increasing in size as they mature over a period of 5 to 6 weeks.

During this process, Yumbolt Autoflower will develop its distinct aromas and flavors as well as dense resinous buds that are ready for harvesting when their trichomes turn amber. Additionally, growers should pay close attention to any signs of nutrient deficiencies or pests throughout each growth phase so that these can be addressed before harvest to maximize yields. All in all, growing Yumbolt Autoflower typically requires just 8–10 weeks from planting until you’re ready to enjoy your home-grown cannabis!


The recommended temperature for the Yumbolt Autoflower strain is between 70 and 80 degrees Fahrenheit (21-27 Celsius). This strain thrives best in warm, dry climates with plenty of sunlight. It can survive temperatures up to 85ºF (29ºC) but this should be avoided if possible as it will reduce yields significantly. 

When grown indoors, a good rule of thumb is to keep your room temperature steady around 75-80°F (24-27°C), as this will ensure healthy growth throughout all stages of development. In addition to keeping temperatures at an ideal level, it’s also important to maintain high levels of humidity, preferably between 45%-55% RH, while the plants are in their vegetative stage. 

Once they enter the flowering stage, however, you should lower the humidity to 40%-50%. Finally, make sure that your growing area has adequate airflow; too much air movement can cause problems like mold or bud rot. Keeping these factors in mind when growing Yumbolt Autoflower will help ensure a successful harvest full of potent buds!


The ideal pH level for the Yumbolt Autoflower strain is between 6.0 and 7.0. This range provides optimal nutrient availability for the plant, allowing it to grow strong and produce high-quality yields. Anything lower than 6.0 can cause nutrient deficiencies, while anything higher than 7.0 can lead to toxicity issues in the plant’s system.

When growing Yumbolt Autoflower indoors, it’s important to monitor your soil or hydroponic solution weekly with a reliable pH meter so you know exactly what your plants are being exposed to at all times throughout their growth cycle. This helps ensure that they stay within the desired range of 6.0-7.0 pH levels and get all of the nutrients they need for successful flowering and yield production! 

Additionally, making sure your water supply is filtered or softened prior to use if necessary will also help keep pH levels in check during cultivation as well as ensuring maximum potency from harvested buds when smoking/vaping them afterwards!


To maximize the yield of the Yumbolt Autoflower strain, it is important to practice good growing techniques and ensure proper environmental conditions. Start by selecting a suitable site with adequate sunlight exposure and soil that is well-draining but nutrient-rich. 

Ensure that your plants have sufficient ventilation and air circulation, as this will help promote healthy growth and strong roots. When watering, use a pH meter or test strips to monitor the acidity levels in order to avoid overfeeding or burning your plants. 

Additionally, make sure you prune away any dead leaves or stems regularly in order to reduce stress on the plant while also allowing more light exposure for healthier buds. Finally, supplementing with organic fertilizer can provide additional nutrients needed for optimal yields. 

Following these steps should help you achieve bigger yields from your Yumbolt Autoflower crop!

Again Grow

My first experience with Homegrown was very pleasing. Seeds were delivered on time, and I had started 2outside and they are almost 2 feet tall! Not bad for only being germinated for 6 weeks. I started my plants indoors in prepared pots for four weeks, then my students transferred them to my garden. If this goes well, I'll be sure to buy more beans next year.
