What Are Fast Flowering Cannabis Strains?
Cannabis cultivation has advanced significantly, offering growers a wide range of options tailored to their needs. Among the exciting developments in recent years are fast flowering cannabis strains—a category of plants bred specifically to mature quickly without sacrificing potency, yield, or flavor. In this article, we’ll explore what fast flowering strains are, how they are developed, their advantages and drawbacks, and why they’re becoming increasingly popular among growers.
What Are Fast Flowering Cannabis Strains?
Fast flowering cannabis strains are specially bred varieties designed to reach full maturity faster than traditional photoperiod cannabis plants. These strains typically transition from the vegetative phase to harvest in 6 to 8 weeks, depending on the specific variety and growing conditions.
Unlike autoflowers, which flower automatically regardless of light cycles, fast flowering strains rely on the same photoperiod mechanism as traditional cannabis. However, their flowering phase is significantly shorter, making them a hybrid solution between photoperiod and autoflower varieties.
How Are Fast Flowering Cannabis Strains Produced?
Fast flowering strains are the result of advanced breeding techniques that combine desirable traits from various cannabis genetics. Here’s how they’re typically developed:
1. Crossing Photoperiod and Autoflower Strains:
Breeders combine a photoperiod strain (such as a popular Sativa or Indica) with an autoflowering strain derived from Cannabis Ruderalis.
The resulting offspring retain the photoperiod flowering trait but inherit the shortened flowering phase from their Ruderalis lineage.
2. Stabilizing Genetics:
Through multiple generations of selective breeding, growers stabilize the hybrid genetics to ensure consistent flowering times, high potency, and desirable flavor profiles.
3. Focusing on Potency and Yield:
Breeders work to maintain the high THC/CBD levels and yields of photoperiod strains while incorporating the fast-growing traits of autoflowers.
Key Characteristics of Fast Flowering Strains
Fast flowering strains offer a unique set of characteristics, including:
Short Flowering Times: Typically ready for harvest in 6 to 8 weeks of flowering.
Photoperiod Dependence: Require light cycle adjustments (12 hours of light/12 hours of darkness) to trigger flowering.
Robust Genetics: Often feature a mix of Sativa, Indica, and Ruderalis traits, combining resilience, potency, and speed.
High Potency: Unlike autoflowers, which sometimes have lower THC levels, fast flowering strains maintain comparable potency to traditional photoperiod varieties.
Advantages of Fast Flowering Cannabis Strains
Fast flowering strains have gained popularity for a reason—they offer several notable benefits to growers:
1. Faster Turnaround:
These strains allow growers to complete multiple harvests in a single growing season, making them ideal for commercial cultivators and home growers alike.
2. Cost Efficiency:
A shorter growth cycle reduces costs associated with electricity, water, and nutrients, making cultivation more affordable.
3. Outdoor Suitability:
Fast flowering strains are excellent for outdoor cultivation in regions with short growing seasons or unpredictable weather. They can often be harvested before the onset of frost or heavy rains.
4. High Potency and Flavor:
Unlike autoflowers, fast flowering strains often retain the high THC levels and terpene profiles of traditional photoperiod plants.
5. Beginner-Friendly:
With shorter flowering times and resilience to pests and diseases, fast flowering strains are easier to manage for novice growers.
Drawbacks of Fast Flowering Cannabis Strains
While fast flowering strains offer many advantages, they also come with some challenges and limitations:
1. Reduced Yield Potential:
Because of their shorter growth cycle, fast flowering strains may produce slightly smaller yields compared to longer-flowering photoperiod strains.
2. Limited Training Time:
The shorter vegetative phase gives growers less time for plant training techniques like topping or low-stress training (LST), which can impact overall yields.
3. Narrow Strain Selection:
While the selection of fast flowering strains is growing, it’s still not as diverse as traditional photoperiod or autoflower varieties.
4. Dependence on Photoperiod:
Unlike autoflowers, fast flowering strains still require light cycle management, making them less convenient for growers seeking simplicity.
Popular Fast Flowering Cannabis Strains
Several fast flowering strains have gained widespread acclaim for their potency, flavor, and rapid growth. Here are a few standout options:
Critical Fast Bud:
Known for its resinous buds and citrusy flavor, this Indica-dominant strain flowers in just 6 weeks.
Green Crack Fast:
A Sativa-dominant hybrid with energizing effects, offering a fruity aroma and flowering in under 8 weeks.
Blueberry Fast Version:
A fast-flowering version of the classic Blueberry strain, delivering sweet, berry-like flavors and relaxing effects.
Northern Lights Fast:
A quick-flowering version of the iconic Northern Lights, known for its sedative effects and earthy flavor.
When to Choose Fast Flowering Strains
Fast flowering cannabis strains are ideal for growers with specific needs or constraints, such as:
Short Growing Seasons: Perfect for regions with limited outdoor growing windows.
Indoor Efficiency: Great for growers looking to maximize efficiency and reduce operational costs.
Beginner Cultivators: Simplifies the growing process for new growers seeking faster results.
Multiple Harvests: Enables multiple grows in a single season, particularly in controlled environments.
Tips for Growing Fast Flowering Cannabis Strains
Optimize Lighting:
Since these plants rely on photoperiod light cycles, ensure a proper 12/12 light schedule to trigger flowering.
Maximize Veg Time:
Extend the vegetative phase slightly to allow plants to grow larger before initiating flowering.
Use Nutrients Wisely:
Feed your plants appropriately, but don’t overdo it, as the shorter cycle means they need less time to uptake nutrients.
Monitor Environment:
Fast flowering strains are resilient but still require optimal humidity, temperature, and airflow to thrive.
