Auto Seeds

42 Fast Buds has specialized in auto breeding for more than 17 years. Our genetics are developed through large-scale population selection, multi-generation stabilization, and continuous performance testing in dedicated facilities.

Today, our autos are grown in more than 50 countries and produced in controlled environments with the capacity to generate and test millions of seeds annually. Our focus is stability, uniform development, high flavorene quality, and reliable performance at population level.

Our breeding approach is based on population work, not single-plant selection.

Each line is developed through:

• Large population selection across generations
• Stress testing and performance validation
• Controlled pollination and in-house seed production
• Continuous improvement based on field feedback

This allows us to maintain uniform growth patterns, predictable flowering times, and consistent results across large numbers of plants.

Yes.

Autos are generally easier to grow than photoperiod plants because they flower automatically based on age and do not depend on light cycle changes.

In addition, modern auto genetics are highly resilient and show strong resistance to environmental stress. They also tend to be less prone to hermaphroditism compared to photoperiod plants, which makes them a reliable option for new growers while still delivering professional-level results.

Yes.

Over the last years, breeding work has focused heavily on flavorene expression and cannabinoid content. Modern autos now offer potency and aroma profiles comparable to photoperiod genetics.

Many current lines show strong flavorene consistency across the population, with complex and stable aromatic profiles.

Yes.

Autos are increasingly used for washing and extraction because they combine high ok production with short cycle times. Faster turnover allows multiple returns per year, and modern ok-focused selections can deliver excellent returns, often comparable or even superior to photoperiod plants under similar conditions.

Most auto seeds finish in approximately 8 - 11 weeks from seed under stable conditions.

Cycle duration depends on:

• Light intensity and daily light hours
• Temperature and environment
• Root development during early growth
• Pot size and substrate
• Early stress or growth interruptions

Because autos have a fixed life cycle, early conditions strongly influence total development time.

Extended cycles are usually caused by environmental factors rather than genetics.

Common causes include:

• Low light intensity
• Overwatering or poor root aeration
• Cold temperatures
• Nutrient imbalance
• Transplant stress
• Heavy training or defoliation

In some cases, very vigorous or high-returning phenotypes may also require slightly more time to fully mature.

Auto size depends heavily on early root development.

The first 2 - 3 weeks are critical. Factors that can limit growth include:

• Small containers or late transplanting
• Overwatering
• Poor aeration in the substrate
• Low light intensity
• Temperature below optimal range

Because vegetative time is limited, early stress directly affects final plant size.

Autos flower automatically, but delayed flowering can occur if early development was slowed.

Typical reasons:

• Low light levels
• Root stress or transplant shock
• Cold conditions
• Nutrient or watering issues

Once environmental conditions improve, flowering usually begins as the plant reaches the appropriate developmental stage.

Yes.

Our lines are developed through multi-generation population selection and tested repeatedly before release. Stability is evaluated at population level, not only on individual plants.

However, plants is a biological crop, and some natural variation between individuals is always expected.

Return depends primarily on environment.

Under optimal indoor conditions with strong lighting, modern autos can produce high returns comparable to many photoperiod plants.

The most important factors are:

• Light intensity
• Container size (recommended 3-5 gallons or more / 10-20 liters)
• Stable environment
• Healthy early growth

Autos perform best under long light schedules.

Common options:

• 18/6
• 20/4
• 24/0

Higher daily light exposure usually improves growth rate and final return.

Light Low Stress Training (LST) is generally safe and can improve canopy structure.

High-stress techniques such as topping, heavy defoliation, or supercropping should be used carefully, especially during early growth, since recovery time is limited.

Yes.

Because they flower based on age rather than daylight hours, autos are ideal for outdoor cultivation and allow multiple returns per season in many climates.

Autos are stabilized through population selection across multiple generations. Working with large populations allows breeders to evaluate uniformity, flowering timing, structure, flavorene expression, and stress resistance at scale.

This approach produces lines that perform consistently in real-world growing conditions, not only under small test environments.
