How to Grow

Setup and Equipment

Growing Space

The Southern Lights strain thrives in a spacious environment that allows for ample growth both vertically and horizontally. A room or tent should be at least 7 feet tall to accommodate the stretch of this sativa-dominant plant. Horizontal space is equally important, with a recommended area of at least 4 square feet per plant to allow for lateral branching. Adequate spacing is crucial for air flow and light penetration to the lower branches.

Lighting

For Southern Lights, full-spectrum LED lights are ideal, providing a balance of cool and warm light that mimics natural sunlight. Positioning LED panels 18 to 24 inches above the plants will promote robust growth. Alternatively, High-Pressure Sodium (HPS) lights can be used during the flowering stage to encourage higher yields, but they should be placed further away from the canopy to prevent heat stress.

Ventillation

Proper ventilation is critical for Southern Lights to prevent mold and mildew. A combination of exhaust fans and oscillating fans will maintain air movement and strengthen plant stems. Introducing carbon dioxide into the growing space can significantly increase growth rates and yield, but this should be done with precision to avoid toxicity.

Temperature and Humidity Control

Southern Lights prefers a temperature range of 68-78°F during the day, with a slight drop at night. Humidity levels should be kept between 40-50% during the vegetative phase and reduced to 30-40% during flowering to prevent bud rot. Consistent monitoring and adjustment of these parameters are critical for optimal plant health and resin production.

Hydroponics vs. Soil

Hydroponics can accelerate the growth of Southern Lights by providing nutrients directly to the roots and allowing for greater oxygen uptake. This method can result in faster vegetative growth and larger yields. Soil, on the other hand, can contribute to the complexity of the terpene profile, enhancing the lemon flavor characteristic of this strain. Both methods have their merits, and the choice depends on the grower's preference for yield or flavor profile.

Germination and Seedling Care

Transition to Vegetative Stage

The Southern Lights strain, a sativa-dominant hybrid, requires a shift in light schedule to enter the vegetative phase. Transition plants from an 18/6 to a 24/0 light schedule, providing continuous light to promote growth. Implement plant training techniques such as topping and low-stress training (LST) to encourage a bushier canopy and increase light exposure to lower branches, optimizing yield potential.

Maintenance

Regular maintenance is critical for Southern Lights. Prune to remove lower growth that receives little light, enhancing air circulation and focusing the plant's energy on top growth. Defoliation should be performed sparingly; remove only large leaves that shade bud sites. Monitor for pests and diseases, and adjust humidity and temperature to maintain plant health.

Flowering Triggers

To induce flowering in Southern Lights, adjust the light schedule to 12/12, with 12 hours of uninterrupted darkness. This mimics the natural transition to autumn, triggering the flowering response.

Harvesting and Curing

Harvest Signs

Identifying the optimal harvest time for Southern Lights is critical for maximizing potency and flavor. Observe the trichomes with a magnifying glass; when most trichomes shift from clear to a milky white, with some turning amber, harvesting time is near. Additionally, the pistils should darken and curl inward. These visual cues indicate peak THC levels and the onset of CBD production, signaling readiness for harvest.

Harvesting Techniques

Harvesting Southern Lights requires precision. Use sharp, sterilized scissors to cut the branches, removing large fan leaves. Then, delicately trim the smaller sugar leaves that surround the buds, taking care not to damage the trichomes. This process preserves the cannabinoids and terpenes responsible for the strain's effects and flavors.

Drying and Curing

Drying and curing are vital for enhancing Southern Lights' aromatic profile and potency. Hang the trimmed branches upside down in a controlled environment with temperatures around 60-70°F and humidity levels at 45-55%. This ensures even drying over 7-10 days. After drying, place the buds in airtight containers, opening them daily for a few minutes to exchange air and release moisture. This curing process should continue for at least two weeks, though longer curing can further improve quality.

Storage

Proper storage of Southern Lights is essential for maintaining its quality. Store the cured buds in airtight containers made of glass or food-grade stainless steel, away from direct light and at a stable temperature. This preserves the cannabinoids and terpenes, ensuring the strain's effects and flavors remain intact. Check periodically for mold or mildew and adjust storage conditions if necessary to protect the buds' integrity.

Site Selection and Preparation

Location

Selecting an optimal location is critical for the success of Southern Lights. The site must receive ample sunlight, as this strain thrives in environments with generous light exposure. Shielding plants from harsh winds is equally important to prevent physical damage and stress. Additionally, privacy is a key consideration to protect the grow from unwanted attention and to comply with local regulations.

Soil Type and Preparation

Southern Lights flourishes in soil with a pH level between 6.0 and 7.0. The ideal texture is loamy, offering a balance of drainage and water retention. Nutrient-rich soil is vital, with an emphasis on nitrogen, phosphorus, and potassium. To optimize the soil, incorporate organic matter such as compost, and test the pH regularly, adjusting with lime or sulfur as needed. Preparing the site involves tilling the soil to aerate it, which promotes root growth and nutrient uptake.

Water Source

Consistent access to water is essential for Southern Lights, as irregular watering can lead to stress and affect yield quality. If rainfall is inconsistent, setting up an irrigation system is crucial. Drip irrigation is efficient, reducing water waste and minimizing the risk of mold and pests. The system should be adjustable to meet the changing hydration needs throughout the plant's life cycle.

Planting and Early Care

Timing

For optimal growth, Southern Lights should be planted outdoors after the last frost when soil temperatures consistently exceed 15°C (59°F). In most temperate climates, this period falls between late April and early June. Growers in warmer regions can plant as early as March, while those in cooler zones may need to wait until mid-May or June. Monitoring local weather patterns is critical for timing the planting of Southern Lights to coincide with stable, warm conditions.

Planting Techniques

Begin by acclimating Southern Lights seedlings or clones to outdoor conditions through a process called hardening off. Gradually expose plants to outdoor temperatures and sunlight over 7-10 days to reduce transplant shock. When transferring outdoors, space plants at least 1 meter apart to allow for adequate airflow and growth. Dig holes twice the size of the root ball and mix in compost or well-rotted manure to enrich the soil. Water thoroughly after planting to settle the soil around the roots and establish good contact.

Protection

Young Southern Lights plants are vulnerable to pests, animals, and extreme weather. Use cloches or row covers to shield plants from harsh conditions and retain soil warmth. Install fencing to deter animals such as deer or rabbits. For pest management, introduce beneficial insects like ladybugs or apply neem oil as a natural deterrent. Regularly inspect plants for signs of stress or damage and adjust protection methods accordingly to maintain optimal growing conditions.

Maintenance Through Growth Phases

Nutrient Management

Outdoor cultivation of Southern Lights requires a dynamic approach to nutrient management, adapting to the plant's changing needs throughout its lifecycle. During the vegetative stage, focus on nitrogen-rich fertilizers to support foliage growth. Transition to phosphorus and potassium-heavy nutrients as the plant enters the flowering phase to promote bud development. Calibrate feeding schedules based on soil tests and plant appearance, reducing nitrogen gradually as flowering progresses to avoid nutrient burn and optimize resin production.

Weed and Pest Control

For organic pest control, neem oil and insecticidal soaps effectively deter common cannabis pests like spider mites and aphids without harming the plant. Introduce beneficial insects such as ladybugs to control pest populations naturally. For diseases like powdery mildew, apply a baking soda and water mixture as a preventative measure. Chemical solutions should be a last resort, with pesticides specifically labeled for use on cannabis applied according to manufacturer instructions to minimize plant stress and contamination.

Pruning and Training

Pruning Southern Lights enhances light penetration and air flow, critical for outdoor growth. Remove lower branches that receive little light to direct energy to top growth. Implement topping by cutting the main stem above a node to encourage multiple colas. Employ trellising to support branches and maintain an even canopy, maximizing light exposure. Low-stress training involves gently bending and tying branches to alter plant structure without cutting, promoting an even distribution of growth and light absorption.

Harvesting and Curing

Timing the Harvest

To determine the optimal harvest time for Southern Lights, a sativa strain, closely examine the trichomes and pistils. Trichomes should transition from clear to a milky white color, indicating peak THC levels. Some trichomes may turn amber, signaling the onset of more sedative effects. Pistils, initially white, will darken to a reddish-brown hue as maturity approaches. Harvesting when most trichomes are milky and pistils are darkened will capture the strain's full potential for arousal, upliftment, creativity, euphoria, and happiness.

Harvesting Techniques

Efficient harvesting of Southern Lights begins with sharp, clean scissors to trim the buds from the plant. Cut branches individually and remove large fan leaves to enhance airflow and light exposure to the remaining buds. This selective trimming allows the plant to focus energy on developing the remaining buds, potentially increasing overall yield and potency. Handle buds gently to preserve trichomes and avoid loss of the aromatic lemon profile.

Drying and Curing

Drying and curing Southern Lights outdoors or in non-controlled environments requires careful attention to humidity and temperature. Hang trimmed buds upside down in a space with good air circulation, away from direct sunlight. Ideal conditions are 50-60% humidity and a temperature around 70°F (21°C). This controlled environment prevents mold growth and preserves cannabinoids and terpenes. Curing involves placing dried buds in airtight containers, opening them daily for the first week to release moisture and allow fresh air in. This process, lasting at least two weeks, refines the flavors and enhances the strain's therapeutic effects for headaches, seizures, and PTSD.

Storage

Proper storage is critical for maintaining the potency of Southern Lights and preventing mold and degradation. Store buds in airtight containers made of dark glass to block light, which can degrade cannabinoids. Keep these containers in a cool, dark place to preserve the strain's efficacy and aromatic profile. Regularly check for signs of excess moisture to prevent mold. By maintaining these conditions, the strain's qualities remain intact for an extended period.
