6. Growing Kandahar Cannabis Strain
The Jet Fuel OG (JFOG) cannabis strain is a popular hybrid, known for its robust effects and pungent, fuel-like aroma. Cultivating Jet Fuel OG involves several specific scientific and practical considerations to maximize yield and maintain the high quality of the plant. Here’s a more detailed look at the methods of cultivating Jet Fuel OG:
Genetic Background
Jet Fuel OG is a hybrid strain, typically a cross between the popular strains 808 Headband and SFV OG Kush. This combination results in a strain with a potent THC content, often exceeding 20%, and a distinctive aroma that combines diesel fuel with earthy, citrusy undertones.
Understanding the strain’s genetics is crucial for cultivation, as it informs decisions on growth behavior, environmental requirements, and potential challenges during cultivation. Jet Fuel OG tends to have a moderate-to-high growth rate with a moderate stretch during the flowering phase, which can influence how much space is needed for the plants to grow.
Cultivation Environment
Jet Fuel OG can be grown both indoors and outdoors, but it thrives best in controlled indoor environments where its growth can be closely monitored. However, outdoor cultivation can also yield excellent results in optimal climates.

Indoor Cultivation
- Temperature: For optimal growth, the temperature should be kept between 65°F and 80°F (18°C to 27°C). Temperatures above 85°F (29°C) can stress the plants and cause them to produce fewer cannabinoids.
- Humidity: During the vegetative phase, maintaining a humidity level of around 60-70% is ideal. As the plants transition into flowering, it is crucial to reduce humidity levels to around 40-50% to prevent mold and mildew growth.
- Lighting: As an indica-dominant hybrid, Jet Fuel OG thrives with high-intensity lighting. A 12-hour light/dark cycle is needed for flowering, and the use of full-spectrum LED lights or high-pressure sodium (HPS) lights is recommended for both vegetative and flowering stages.
Outdoor Cultivation
- Climate: Jet Fuel OG prefers a Mediterranean climate with plenty of sunlight and warm temperatures. It grows best in areas with long, sunny days and moderate humidity.
- Soil: Rich, well-draining soil is essential for healthy Jet Fuel OG plants. Loamy or sandy soil with a slightly acidic pH (6.0-6.5) tends to support better root growth and nutrient uptake.
Growth and Training Techniques
Jet Fuel OG can grow quite tall, and its plants may benefit from certain training techniques that control their height and encourage bushier growth. These methods help manage the strain’s structure for better light penetration and air circulation, which are crucial for maximizing yield and minimizing the risk of diseases.
Common Training Methods
- Topping: Cutting off the top of the main stem can encourage lateral branching, making the plant bushier and increasing the number of main colas (flowering tops). This is particularly important with Jet Fuel OG as it tends to stretch during flowering.
- Low-Stress Training (LST): Gently bending and tying down branches to create an even canopy ensures that more of the plant is exposed to light, increasing yield. LST helps prevent the plant from growing too tall and makes it easier to maintain in smaller spaces.
- Sea of Green (SOG): This method involves growing many small plants with one main cola each, which maximizes space and light exposure. It’s particularly useful in smaller indoor setups where space is limited.
- ScrOG (Screen of Green): Using a mesh screen to support the branches, ScrOG encourages horizontal growth and ensures an even distribution of light across the plant. This method is ideal for controlling the height of Jet Fuel OG while encouraging high yields.
Feeding and Nutrient Management
Jet Fuel OG requires proper feeding throughout its growth stages to ensure it reaches its full potential. Its nutrient requirements differ between the vegetative and flowering phases.
- Vegetative Stage: During this phase, the plant needs higher levels of nitrogen to promote strong stem and leaf growth. A balanced fertilizer with a higher nitrogen content (N-P-K ratio of around 3:1:2) is ideal.
- Flowering Stage: As the plant enters the flowering phase, it requires more phosphorus and potassium to support bud development. A fertilizer with an N-P-K ratio closer to 1:3:2 or 2:3:4 is recommended to ensure that the plant has enough resources for proper flower formation.
It’s also important to monitor the pH levels of the water and soil. Jet Fuel OG prefers a slightly acidic pH level between 6.0 and 6.5 for optimal nutrient uptake. Over-fertilizing or under-fertilizing can lead to nutrient burn or deficiencies, both of which can impact the plant’s yield and quality.
Watering and Irrigation
Jet Fuel OG has moderately high water requirements, but overwatering should be avoided. The plant prefers consistent moisture in the soil, but it must have good drainage to prevent root rot.
- Watering Frequency: During the vegetative phase, watering can be done every 2-3 days, depending on the size of the container and environmental conditions. During flowering, it’s important to let the soil dry out slightly between waterings to avoid waterlogging.
- Irrigation System: In large-scale cultivation, hydroponic systems or drip irrigation can provide a consistent water supply while ensuring that the plant’s roots are well-oxygenated. These systems are ideal for controlling the amount of water and nutrients the plants receive.
Flowering and Harvesting
Jet Fuel OG typically takes between 8 and 9 weeks to complete its flowering cycle indoors, although outdoor growers may see a later harvest in the fall (late October to early November). The buds of Jet Fuel OG are dense, coated in trichomes, and emit a pungent, diesel-like aroma when they are fully mature.
Trichome Development
The trichomes on Jet Fuel OG are important indicators of when the plant is ready for harvest. These glandular structures produce cannabinoids and terpenes, contributing to the strain’s effects and aroma. By closely monitoring trichome development, growers can determine the optimal harvest window.
- Clear Trichomes: At this stage, the THC levels are still developing, and the effect may be less potent.
- Milky Trichomes: This is the ideal time to harvest for maximum THC potency. The buds will have a strong aroma and produce a euphoric, energizing high.
- Amber Trichomes: If left too long, the trichomes turn amber, which indicates that the THC is degrading into CBN. The high will become more sedative, and the overall potency may decrease.
Harvesting Tips
- Timing: Harvesting is best done early in the morning when the plants’ terpene profiles are at their peak.
- Trimming: After cutting the buds, they should be carefully trimmed to remove excess leaves, ensuring that the final product is high-quality.
Post-Harvest
After the buds are harvested, proper drying and curing processes must be followed to preserve the quality of the Jet Fuel OG flowers.
Drying
- Hang the buds upside down in a well-ventilated area with temperatures between 60-70°F (15-21°C) and humidity levels of around 50-60%.
- Drying typically takes 7-14 days, depending on the size of the buds and environmental factors. Over-drying can lead to loss of terpenes, which affects the flavor and aroma.
Curing
- After drying, the buds should be placed in glass jars and opened periodically to allow the release of moisture and to promote further curing. This procedure may take two to four weeks.
- Proper curing enhances the flavor, potency, and smoothness of the final product.
Potential Cultivation Challenges
Cultivating Jet Fuel OG can present a few challenges that growers need to address:
Nutrient Deficiencies: Common deficiencies include nitrogen, phosphorus, and potassium imbalances. Monitoring and adjusting nutrient levels can prevent these issues.
Pest Management: Like all cannabis strains, Jet Fuel OG is susceptible to pests such as spider mites, aphids, and whiteflies. Frequent examination and the application of natural pest management techniques, such as neem oil or beneficial insects, are crucial.
Mold and Mildew: Due to its dense bud structure, Jet Fuel OG can be prone to mildew and mold, particularly in areas with high humidity. Proper ventilation and humidity control are critical during the flowering phase.
