When it comes to growing cannabis, the traditional growth cycle involves two main stages: the vegetative (veg) stage and the flowering stage. While the vegetative stage allows plants to grow larger and develop a robust structure, some growers choose to skip this stage altogether. This method, often referred to as "12/12 from seed" or "straight to flower", has become an intriguing approach among cannabis cultivators. In this article, we will explore the benefits of skipping the veg cycle when growing cannabis, focusing on yield, time efficiency, resource management, and overall plant health.
In the veg stage, cannabis plants grow under a lighting schedule of approximately 18-24 hours of light daily. During this time, the plant focuses on developing strong stems, large leaves, and an extensive root system. This stage typically lasts between 4 to 8 weeks (or more, depending on the grower's goals and strain characteristics).
The flowering stage begins when the light cycle is reduced to 12 hours of light and 12 hours of darkness, mimicking the natural light changes as seasons transition. This stage is when the plant starts producing buds, which are the sought-after component for cannabis use.
By skipping the veg stage and going directly to the flowering stage, growers significantly alter this traditional growth cycle. Below, we’ll delve into the reasons why this alternative approach can be beneficial.
One of the primary benefits of skipping the veg cycle is the significant reduction in overall growth time. Traditional cultivation can take 3 to 6 months from seed to harvest, largely due to the extended veg phase. By starting plants on a 12/12 light cycle, growers can shorten the total cultivation time to as little as 8-12 weeks.
This speed is particularly advantageous for:
Commercial growers aiming for quick turnover.
Home cultivators looking to produce their own supply without a long wait.
Seasonal growers seeking to fit multiple harvests into a single year.
By eliminating the veg phase, plants focus solely on bud production after sprouting, streamlining the process.
Skipping the veg stage results in smaller, more compact plants. This feature is particularly beneficial for growers with limited space, such as:
Closet grows
Micro grows
Tent setups
Small-scale cannabis cultivation is increasingly popular among urban growers who need to maximize yields in confined areas. Plants grown directly under a 12/12 cycle tend to reach heights of only 1-3 feet, making them ideal for spaces with height restrictions.
The vegetative stage demands significant resources, including:
High light intensity for extended hours (18-24 hours/day).
Nutrients for robust vegetative growth.
Water to support the plant's rapid development.
By skipping the veg phase:
Electricity costs decrease, as lights are used only 12 hours daily.
Nutrient consumption drops, since plants require fewer vegetative fertilizers.
Water usage is minimized, aligning with environmentally friendly cultivation practices.
For budget-conscious growers, reducing these costs can make a substantial difference over multiple harvest cycles.
For growers who value discretion, smaller plants grown without a veg cycle are much easier to conceal. Additionally, these plants tend to emit less odor compared to larger, bushier plants. This reduced smell can be a critical factor for:
Indoor growers in shared living spaces.
Outdoor growers cultivating in neighborhoods or areas with strict cannabis regulations.
Compact plants are also less noticeable in outdoor setups, blending more seamlessly with surrounding vegetation.
Traditional growing methods often involve techniques like topping, low-stress training (LST), and high-stress training (HST) to optimize yields. These methods require time and expertise during the veg stage.
With a 12/12 light cycle:
Training is largely unnecessary since the plant remains naturally compact.
The focus shifts to optimizing light penetration and airflow during the flowering phase.
This simplicity appeals to beginner growers who want a low-maintenance approach to cannabis cultivation.
Skipping the veg cycle aligns perfectly with the Sea of Green (SOG) growing method. SOG involves growing many small plants in close proximity to maximize yields in a small area. By switching to the flowering stage immediately:
Plants develop one or two main colas instead of multiple branches.
Growers can achieve high yields per square foot by prioritizing canopy density.
The SOG method combined with a 12/12 cycle offers a streamlined, efficient approach to cultivation.
While smaller plants generally produce lower total yields compared to fully vegged plants, some growers report that skipping the veg stage may lead to higher THC concentrations in the buds. This theory suggests that plants under stress, such as reduced vegetative growth, may produce more trichomes as a survival mechanism.
Although more research is needed to substantiate this claim, growers who prioritize potency over quantity may find this approach advantageous.
While skipping the veg cycle offers numerous benefits, it’s not without challenges. Here are a few considerations for growers:
Since plants have less time to grow large and develop multiple bud sites, the total yield per plant is typically lower than with traditional growing methods. To compensate, growers may need to:
Increase the number of plants in a grow space.
Focus on strains known for high yields under 12/12 conditions.
Not all cannabis strains respond well to skipping the veg cycle. Indica-dominant strains generally perform better under 12/12 schedules due to their naturally compact growth habits. On the other hand, sativa-dominant strains may struggle to develop adequately without a veg phase.
For growers accustomed to advanced training techniques, skipping the veg cycle can feel limiting. Techniques like LST, topping, and super cropping are harder to implement when plants are immediately focused on flowering.
Plants skipping the veg stage require careful nutrient management to avoid deficiencies. Since the focus is on flowering, growers must provide nutrients rich in phosphorus and potassium from the start while avoiding excessive nitrogen.
If you're considering skipping the veg stage, here are some tips to optimize your results:
Choose the Right Strains: Look for strains that are naturally compact and fast-flowering.
Maximize Light Efficiency: Use high-quality LED or HID lights to ensure plants receive sufficient light during the 12-hour period.
Monitor Plant Health Closely: Without the veg phase, plants have less time to recover from stress, so ensure optimal environmental conditions.
Optimize Your Grow Space: Use reflective materials and strategic plant placement to maximize light distribution.
Skipping the veg cycle when growing cannabis is a unique approach that offers numerous advantages, including faster harvest times, reduced costs, and a simplified growing process. While this method may not be suitable for every grower, it’s an excellent option for those with limited space, time, or resources. By understanding the benefits and challenges, cultivators can decide whether this alternative approach aligns with their goals and growing conditions.
Whether you're a novice seeking simplicity or an experienced grower looking to experiment, skipping the veg cycle provides an intriguing opportunity to explore new possibilities in cannabis cultivation.
