Sour Diesel is one of the most iconic cannabis strains, known for its pungent aroma, energizing effects, and strong sativa dominance. Cultivating this strain can be incredibly rewarding, but it requires attention to detail and a clear understanding of its growth cycle. Whether you're a first-time grower or a seasoned cultivator, following a structured timeline can help you get the most out of your Sour Diesel plants.
Week 1-2: Germination and Seedling Stage
The journey begins with germination. Most growers use the paper towel method or plant directly into a starter medium. Within a few days, the seeds will sprout, and tiny seedlings will emerge. During this stage, it's important to provide 18-24 hours of light per day and maintain humidity around 65-70%. Keep the temperature between 70-75°F. The seedlings will develop their first set of true leaves by the end of week two.
Week 3-4: Early Vegetative Stage
Now that the seedlings have established roots, they enter the vegetative stage. You’ll notice rapid growth in both height and foliage. This is the time to transplant them into larger containers. Maintain a light schedule of 18 hours on and 6 hours off. Nutrients should be introduced gradually, focusing on nitrogen-rich formulas. Keep humidity around 50-60% and temperatures between 72-78°F.
Week 5-6: Late Vegetative Stage
Sour Diesel plants can grow tall, so this is the time to start training techniques like topping or low-stress training (LST) to manage height and encourage bushier growth. The plants will need more nutrients and water as they grow. Continue with the same light schedule and monitor for any signs of nutrient deficiencies or pests. By the end of week six, your plants should be strong, healthy, and ready for flowering.
Week 7-8: Transition to Flowering
Switch your light cycle to 12 hours on and 12 hours off to initiate flowering. During this transition, plants may stretch significantly, sometimes doubling in height. This is known as the flowering stretch. Start introducing bloom nutrients with higher phosphorus and potassium levels. Humidity should be lowered to 40-50% to prevent mold, and temperatures should remain between 68-75°F.
Week 9-12: Flowering Stage
This is when Sour Diesel starts to show its true character. Buds begin to form and swell, and the signature diesel aroma becomes more noticeable. Trichomes will develop, and pistils will change color over time. Keep feeding with bloom nutrients and monitor trichome development to determine the best harvest window. Reduce humidity further to around 40% and ensure good air circulation.
Week 13-14: Harvest and Curing
Once the trichomes turn milky with some amber, it's time to harvest. Cut the plants and hang them upside down in a dark, well-ventilated area with 50% humidity and temperatures around 65-70°F. After 7-10 days, when the branches snap rather than bend, it's time to trim and cure the buds in glass jars. Open the jars daily for the first week to release moisture, then less frequently over the next few weeks.
Final Thoughts
Growing Sour Diesel takes patience and care, but the results are well worth the effort.
