Cultivation Information
Genetics and Breeding
JGR is a hybrid strain resulting from the cross of Jet Fuel and Gelato. The Jet Fuel lineage contributes to the strain’s powerful diesel-like aroma, while Gelato provides a sweet, dessert-like flavor. This hybrid is known for its strong potency, high THC levels, and complex terpene profile.

Breeders specifically select parents that exhibit desirable traits such as high THC content, aromatic profile, and yield potential. To maintain the stability and consistency of the JGR strain, it is often bred using regular seeds, which ensure that both male and female plants are produced. This allows for genetic diversity and facilitates further breeding efforts.
Environment and Climate
JGR thrives in a Mediterranean climate where the temperature is warm, with daytime highs between 70°F and 85°F (21°C to 29°C). The strain requires a period of warmth and ample sunlight for optimal growth, making it well-suited to outdoor cultivation in regions that experience a long growing season.
However, if cultivating JGR in regions with less favorable climates, growers may opt for indoor cultivation using climate-controlled environments. The plant responds well to controlled lighting cycles, which can simulate its natural light exposure. Indoor cultivation often requires the following environmental settings:
- Light Cycle: A 12/12 light cycle (12 hours of light and 12 hours of darkness) is necessary for flowering.
- Temperature: During the day, temperatures should be kept between 70°F and 80°F (21°C to 27°C), with nighttime temperatures dropping slightly to simulate natural day-night fluctuations.
- Humidity: During the vegetative stage, JGR benefits from moderate humidity levels (60-70%), while during the flowering stage, lower humidity (40-50%) helps prevent mold and mildew growth.
- Air Circulation: Adequate airflow is essential for the development of strong stems and to prevent the growth of pathogens.
Soil and Medium
JGR can be grown in both soil and hydroponic systems, but soil cultivation tends to be preferred by those who seek a more natural growth process with rich flavor profiles. When using soil, the following guidelines should be observed:
- Soil Composition: A well-draining, slightly acidic soil with a pH level between 6.0 and 6.5 is ideal for JGR cultivation. Loamy or sandy soils are most suitable, as they allow roots to access oxygen while also retaining enough moisture.
- Soil Nutrients: Organic fertilizers with a balanced NPK (nitrogen, phosphorus, potassium) ratio work well for JGR plants. During the vegetative phase, a higher nitrogen content is beneficial to promote leafy growth, while during the flowering phase, a higher phosphorus content supports bud development.
In hydroponic systems, coco coir or perlite is often used as a growing medium. These mediums help provide aeration and moisture retention without becoming overly compacted, offering the plant roots the right amount of oxygen and nutrients.
Training and Pruning
JGR is a bushy, vigorous plant that can grow tall if not properly managed. To maximize yields and maintain plant health, several techniques are often employed to train and prune the plant.
- Topping: Topping involves cutting off the top of the plant during the vegetative stage to encourage the growth of lateral branches. This helps the plant grow horizontally and develop multiple colas (flowering tops) rather than a single main stem.
- Low-Stress Training (LST): LST techniques involve gently bending and tying down branches to create an even canopy. This improves light penetration to all parts of the plant and helps increase the overall yield.
- Defoliation: Removing large leaves that obstruct light from reaching the lower branches can improve airflow and light exposure to the bud sites. To prevent harming the plant, this should be done carefully.
Additionally, screen of green (SCROG) techniques can be used in both indoor and outdoor cultivation. This involves using a screen to spread the branches horizontally, which helps evenly distribute the plant’s energy and supports the buds during flowering.
Nutrient Management
The JGR cannabis strain has a relatively high demand for nutrients, particularly during its rapid growth phases. However, it is essential to balance the nutrient intake to avoid nutrient burn or deficiencies.
- Vegetative Stage: During the vegetative stage, JGR plants require higher levels of nitrogen to promote healthy leaf and stem growth. However, too much nitrogen in the flowering stage can hinder bud development.
- Flowering Stage: When entering the flowering stage, plants should be switched to a fertilizer blend with a higher phosphorus and potassium ratio. These elements are crucial for flower development and resin production.
- Micronutrients: Along with macronutrients, JGR also benefits from micronutrients such as magnesium, calcium, and iron to support optimal growth. Magnesium helps with chlorophyll production, while calcium aids in cell wall development.
Flowering and Harvest
JGR typically takes 8 to 9 weeks to fully flower, depending on environmental conditions and cultivation techniques. During the flowering stage, growers need to monitor for the following:
- Bud Development: Buds will become larger and more densely packed as the plant matures. JGR is known for its resinous buds, which have a strong diesel scent and a unique color palette of green and purple hues.
- Trichome Production: The formation of trichomes (the small resin glands on the surface of the buds) is essential for the strain’s potency and aroma. Growers should monitor trichome color to determine the ideal harvest time. Trichomes transition from clear to cloudy and eventually amber, with peak potency generally occurring when they are mostly cloudy.
- Pest and Disease Control: Like many cannabis plants, JGR is susceptible to pests and diseases, such as spider mites, aphids, and powdery mildew. Integrated pest management (IPM) strategies, such as the use of beneficial insects (ladybugs, predatory mites) or organic pesticides, can help prevent and treat infestations without harming the plants.
Post-Harvest Processing
After harvest, JGR buds need to be carefully dried and cured to preserve their potency and flavor. This process includes:
- Drying: Buds should be hung upside down in a well-ventilated area with temperatures between 60°F and 70°F (15°C to 21°C) with a 50% relative humidity. This allows the buds to dry slowly without molding.
- Curing: Once dried, the buds should be placed in airtight containers, such as glass jars, for curing. Curing allows the remaining moisture to distribute evenly throughout the buds, enhancing flavor and aroma while ensuring a smoother smoking experience.
Yield Potential
JGR plants can produce high yields if provided with optimal care. Under ideal conditions, the yield can range from 450 to 600 grams per square meter indoors and 500 to 800 grams per plant outdoors. The strain’s bushy nature and extensive branching typically lead to a substantial number of flower sites, which contributes to its high yield potential.
