The dominant Sativa genes of Sour Diesel mean that it is naturally tall and lanky. Under the right conditions, it can grow equally well either indoors and outdoors. But no matter where it is grown, take note that the odor emanating from it is especially pungent. This makes it challenging to have a discreet crop. Moreover, your chief concern should be to keep the growing area clean and dry. Doing so will help prevent powdery mildew infestations. This fungal disease spreads quickly, and can reduce the quality and quantity of your yield.
If you choose to grow indoors, keep the relative humidity (RH) at 65 to 70% during the vegetative stage. Drop it by 10 to 15% when the plant starts flowering. These dry conditions decrease the risk of fungal, bacterial, and viral infections. As for the temperature, do not let your grow room get hotter than 85 degrees Fahrenheit (29.5 degrees Celsius). When the lights are off, the minimum temperature is 68 degrees Fahrenheit (20 degrees Celsius). If you find it too cold, a space heater could be a worthwhile investment.
As mentioned earlier, Sour D’s height can be controlled using the Screen of Green (SCROG) training technique. While your plant is still in the vegetative stage, you can bend the shoots outwards, away from the main stem. There is really no need to cut them – simply use cable ties and skewers, or even duct tape. By promoting sideways growth, you expose the bud sites on the lower part of the plant to more light, ensuring a heavier yield.
Outdoors, you can leave the plant to reach its maximum height of 6.5 feet (200 cm). It needs lots of sunlight, typical of strains emerging from California. As part of the Chemdawg family, its nutrient requirements are pretty high. A good-quality soil is sufficient when it is still a seedling, but it will demand more nitrogen as it vegetates. Make sure to mind the pH level, too, as it can affect the plant’s ability to absorb what you feed it. Follow this guide for a trouble-free grow.
Our Sour Diesel seeds are feminized which guarantees that your plants will be all-female. As this 2017 report states, having male plants around will damage your crop. The pollen from males will taint the females’ flowers, producing seeds instead of smokable buds. Eliminating the male sex chromosomes also permits a higher THC content. In the case of this strain, it is an impressive 20%.
As harvest time approaches, you will begin to see dense nuggets covered in shiny crystals, giving the appearance of being covered in frost. The pistils, or tiny hairs, interspersed among the buds are pinkish-orange in color. To dry them properly, hang the plants in an environment that is 70 degrees Fahrenheit (21 degrees Celsius) and 50% RH. You can cure them after a few days, after which you can start enjoying them or store them in a cool, dry place for later.
