The combination of OG Kush and Larry OG in this hybrid strain results in unique growth characteristics that both novice and experienced cultivators should understand in order to achieve optimal yields and quality.

1. Genetic Stability and Phenotype Variability

Grandpa Larry OG, being a hybrid, inherits genetic traits from both its parents (OG Kush and Larry OG). As is the case with many hybrids, Grandpa Larry OG can exhibit phenotypic variability—meaning that different plants of the same strain may have slight variations in appearance, yield, and potency.

  • OG Kush Genetics: This variety is known for its compact stature and its ability to thrive in controlled environments. OG Kush can be more susceptible to environmental stress, so it’s important to monitor temperature and humidity levels closely.
  • Larry OG Genetics: Larry OG, a slightly more indica-dominant phenotype, tends to produce larger yields with dense buds. It’s also noted for its faster flowering time, compared to more traditional OG varieties.
2. Growing Medium

Cannabis plants, including Grandpa Larry OG, can be grown in various media. The choice of medium affects root health, nutrient absorption, and ultimately plant growth.

  • Soil Cultivation: Growing Grandpa Larry OG in soil tends to produce the best flavor profile, as the natural soil nutrients allow the plant to develop its aromatic compounds (terpenes). However, soil can sometimes be tricky in terms of controlling nutrient levels, requiring more attention to detail.
  • Hydroponics: Hydroponic systems, in which plants grow in a water-based solution with added nutrients, allow for quicker growth and larger yields. However, hydroponic systems may not bring out the full flavor profile of the strain as effectively as soil cultivation.
  • Coco Coir: A hybrid medium of soil and hydroponics, coco coir has become increasingly popular due to its ability to provide both aeration and moisture retention. This makes it ideal for cultivators who want to strike a balance between soil and hydroponics.
3. Optimal Climate and Environmental Conditions

Grandpa Larry OG thrives in a Mediterranean-like climate with temperatures ranging between 70°F and 85°F (21°C to 29°C) during the day and slightly cooler temperatures at night. The strain prefers low humidity during the flowering phase to prevent mold growth, especially as the dense buds of Grandpa Larry OG can trap moisture.

3.1 Light Cycle

Like most cannabis plants, Grandpa Larry OG is a photoperiod strain, meaning it requires a specific light/dark cycle to flower. During the vegetative phase, the plant needs 18-24 hours of light to stimulate growth. Once it transitions to the flowering stage, the light cycle should be reduced to Twelve hours of darkness and twelve hours of brightness.

  • In indoor cultivation, controlled lighting systems, such as high-pressure sodium (HPS) or metal halide (MH) lamps, can help mimic the sunlight spectrum to optimize photosynthesis and bud development. LED lights are also gaining popularity due to their energy efficiency and ability to produce a light spectrum that supports healthy growth.
  • In outdoor cultivation, Grandpa Larry OG should ideally be grown in the late spring to early summer to allow the plant to flower in the optimal sunlight during the fall. Outdoor growers should ensure the plants are not exposed to excessive rain or cold during the flowering period to avoid mold and mildew issues.
3.2 Nutrients and Feeding Schedule

Grandpa Larry OG is a heavy feeder, meaning it requires adequate nutrients, particularly during the flowering stage. Key nutrients for cannabis cultivation include:

  • Nitrogen (N): Essential during the vegetative phase, nitrogen supports healthy leaf and stem growth.
  • Phosphorus (P): Crucial for the development of buds, phosphorus is especially important during the flowering phase to help develop dense, resinous flowers.
  • Potassium (K): Potassium plays a role in overall plant health and helps with stress resistance. It’s also necessary during flowering to promote healthy bud production.
4. Flowering and Yield

Grandpa Larry OG typically has a flowering period of about 8 to 10 weeks, depending on the growing environment. The flowering time can be slightly shorter when growing in hydroponic systems compared to soil cultivation, as the plant can receive more efficient nutrient uptake.

  • Indoors: Grandpa Larry OG’s yields range from 350 to 450 grams per square meter under controlled indoor growing conditions.
  • Outdoors: If grown outdoors, the yield can be higher, around 450 to 600 grams per plant, depending on the size of the plant and the environment.

The strain’s dense buds, which are often covered in a thick layer of trichomes, make it especially appealing to growers focused on resin production. These trichomes contain cannabinoids and terpenes, which are essential for both the recreational and medicinal effects of Grandpa Larry OG.

5. Training Techniques

To maximize yields and ensure even canopy growth, various training techniques can be employed during the cultivation of Grandpa Larry OG. These techniques help manage plant growth, allowing for better light penetration and airflow, as well as increased bud production.

  • Low-Stress Training (LST): Entails tying down and gently bending branches to promote horizontal development. This helps prevent overcrowding and increases the overall yield by allowing more colas to receive light.
  • Screen of Green (SCROG): A method where a mesh screen is placed over the plant, and the branches are weaved through the screen to encourage horizontal growth. SCROG is beneficial for indoor cultivators who want to maximize limited space.
  • Topping and FIMing: These methods involve cutting the main stem to encourage the plant to grow multiple main colas, thus increasing the yield. This is particularly effective in indoor cultivation where maximizing vertical space is essential.
6. Pests and Disease Management

Like any cannabis plant, Grandpa Larry OG is susceptible to common pests and diseases. Keeping the growing environment clean and monitoring plant health regularly is key to preventing these issues.

  • Spider Mites: These tiny pests can damage plants by sucking the sap from leaves. Regular inspection and the use of natural predators (like ladybugs) or organic pesticides can help control them.
  • Powdery Mildew: This fungal disease thrives in humid conditions, so maintaining optimal humidity levels (less than 50%) during the flowering phase can help prevent its development.
  • Root Rot: Overwatering or inadequate drainage can lead to root rot, which can severely damage plants. Ensuring proper soil drainage and root health is critical, especially when using soil-based mediums.
7. Harvesting and Curing

Harvesting Grandpa Larry OG at the right time is crucial to ensure the best potency and flavor. The plant is typically ready for harvest when the trichomes turn from milky white to amber, signaling that the plant has reached its peak THC levels.

After harvesting, the buds should undergo a slow and proper curing process to allow the terpenes to develop fully and enhance the flavor. Curing involves hanging the buds in a cool, dark space with proper airflow, and then storing them in glass jars to further cure for several weeks.

Conclusion

Grandpa Larry OG is a potent and versatile hybrid cannabis strain with a variety of recreational and medical uses. Its balanced effects, which combine mental clarity, euphoria, and physical relaxation, make it a well-liked option for both medical cannabis patients and recreational consumers.
