Cultivation Information
1. Genetic Background of KC 33
KC 33 is a hybrid strain, derived from a cross between a Skunk variety and an Afghani Indica. Its genetic mix results in a plant that benefits from the best of both worlds: the fast-growing and high-yielding characteristics of Skunk and the resin production and hardiness of Afghani Indicas. This makes it a suitable strain for both novice and experienced cultivators.
2. Optimal Growing Conditions
Like most cannabis strains, KC 33 requires specific conditions to thrive, which include:
a. Light
KC 33, being a hybrid strain, has moderate light requirements. If growing indoors, it should be exposed to 18 hours of light during the vegetative phase, and the light cycle should be reduced to 12 hours when transitioning to the flowering stage.
For outdoor cultivation, KC 33 thrives in regions that receive a consistent amount of sunlight with temperatures between 70°F (21°C) and 85°F (29°C) during the growing season. Light intensity and photoperiod play a crucial role in its growth and development.
b. Temperature and Humidity
KC 33 plants thrive in moderate temperatures. The optimal range for this strain is between 70°F (21°C) and 80°F (27°C) during the vegetative phase, with a slight drop to 65°F (18°C) during the night. During flowering, slightly cooler temperatures between 65°F (18°C) and 75°F (24°C) are ideal.
Humidity should be controlled carefully. In the vegetative stage, a humidity level of 50-60% is suitable, while during flowering, it should be reduced to 40-50% to prevent mold and mildew from developing.
c. Soil vs. Hydroponics
KC 33 can be successfully cultivated in both soil and hydroponic systems, though each method has different advantages.
- Soil Cultivation: Using high-quality, well-draining soil with a pH level between 6.0 and 7.0 is beneficial for KC 33. A soil-based medium allows the plants to develop a more robust root system and provides a natural nutrient source.
- Hydroponic Systems: Hydroponic cultivation of KC 33 can result in faster growth and larger yields due to the enhanced availability of nutrients and water. Hydroponics also gives the grower more control over nutrient levels and pH. However, it requires more technical expertise and attention to detail.
d. Nutrient Requirements
During the vegetative stage, KC 33 requires a balanced nutrient mix. The nitrogen levels should be higher, as this is essential for leaf and stem growth. In the flowering phase, the plant requires less nitrogen but more phosphorus and potassium for robust flower development.

A typical nutrient schedule includes:
- Vegetative stage: A balanced NPK (Nitrogen-Phosphorus-Potassium) ratio of 3:1:2 or 4:2:3.
- Flowering stage: A high-phosphorus, low-nitrogen NPK ratio, such as 1:2:3 or 1:3:4.
e. pH Levels
Maintaining optimal pH levels is crucial for the healthy growth of KC 33. The pH should be kept between:
- Soil: 6.0 – 7.0
- Hydroponics: 5.5 – 6.5
Maintaining the right pH helps the plant absorb nutrients efficiently, preventing nutrient lockout.
3. Training and Pruning Techniques
Pruning and training techniques are essential for ensuring KC 33 plants develop strong branches and yield large, dense buds. Some common methods include:
a. Low Stress Training (LST)
To promote horizontal growth, LST entails gently bending and tying down branches. This increases light penetration and airflow to the lower branches, resulting in more uniform bud development.
b. Topping
Topping is a technique where the top of the main stem is cut off to promote the growth of two new main stems. This results in a bushier plant with more bud sites and larger yields.
c. Defoliation
Selective removal of older, larger leaves, especially those that are blocking light from reaching the lower branches, can help the plant focus its energy on developing flowers. It is important not to remove too many leaves at once to avoid stressing the plant.
d. Screen of Green (ScrOG)
ScrOG involves placing a net or screen over the plant to train the branches through the screen. This method creates an even canopy and maximizes light exposure to the buds.
4. Flowering Phase
The flowering stage for KC 33 typically lasts 8 to 10 weeks, depending on environmental conditions and growing methods. During this time, the plant’s energy is focused on the production of flowers (buds), and growers must adjust their nutrient regimen to support this transition.
a. Flowering Nutrients
As the plant enters the flowering phase, it should be fed with phosphorus and potassium-rich nutrients to support flower development. The nitrogen levels should be reduced to avoid excessive vegetative growth.
b. Light Cycle
To induce flowering, the light cycle must be reduced to 12 hours of light and 12 hours of darkness. Maintaining a strict light/dark cycle is essential to avoid stressing the plant and triggering issues like hermaphroditism.
c. Monitoring Trichome Development
During the final weeks of flowering, it is essential to monitor the trichomes (the tiny, glandular structures on the buds) to determine the right time for harvest. Trichomes change from clear to milky white and then amber as they mature. Timely harvesting guarantees the ideal flavor profile and potency.
5. Harvesting and Drying
KC 33 plants are typically ready to harvest when the trichomes are milky with some amber coloration. The flowers should be cut carefully at the base of the plant, with attention to preserving the integrity of the buds.
a. Drying
After harvest, the buds should be dried in a well-ventilated, dark space with temperatures between 60-70°F (15-21°C) and humidity levels around 50-60%. It is crucial to avoid excessive humidity, which can lead to mold and mildew.
Drying typically takes 7 to 14 days, depending on the conditions. When touched, the buds should feel dry but not brittle. Once dried, they can be cured in glass jars to improve flavor and potency.
6. Pest and Disease Management
As with all cannabis strains, pest and disease management is crucial for successful cultivation. Common pests that may affect KC 33 include spider mites, aphids, and whiteflies. Regular inspection of plants, particularly the undersides of leaves, is essential to detect and address infestations early.
Fungal diseases such as powdery mildew can also pose a risk, particularly in humid environments. Maintaining proper airflow, humidity control, and using organic fungicides or beneficial bacteria can help prevent these issues.
7. Yield and Harvest Times
KC 33 is known for its high yields, which can vary based on growing conditions and methods. Indoor cultivation typically yields 450-550 grams per square meter, while outdoor cultivation can produce up to 600 grams per plant under optimal conditions. The plant generally takes around 8-10 weeks to flower, with harvest time typically occurring in late September to early October for outdoor growers.
Potential Side Effects
Like all cannabis strains, KC 33 can cause some mild side effects, although these are generally not severe. Among the most typical adverse effects are:
- Dry Mouth: A common side effect of cannabis, dry mouth (also known as “cottonmouth”) can occur with KC 33. Drinking water or consuming hydrating foods can help alleviate this discomfort.
