Sour Diesel cannabis plants are tricky to grow and should only be taken on by experienced growers. This strain grows very tall and can reach heights of well over 6 feet, which means it requires a lot of vertical grow space. Sour Diesel performs better indoors than outdoors, like most cannabis strains, but will grow similarly to an indoor plant if you have access to a greenhouse. While some cultivators prefer to grow in natural sunlight and fresh air similar to that of California in the summer, others prefer the more predictable, controlled environment of growing indoors. Ideally, the temperature should be between 70 and 85 degrees Fahrenheit, with relative humidity between 30-60%. If you are going to grow this strain indoors, you will need to replicate the warm and humid climate to make these plants thrive. If your local weather is similar to these conditions, your crop will perform exceptionally outdoors. However, setting up your grow inside will help you keep the right lighting, humidity, and temperature throughout the grow. Topping, Low-stress training (LST), and pruning methods are ideal for this cannabis strain. These methods will help adjust the canopy to allow light and air to reach every level of the plant, promoting healthy growth from top to bottom. Because Sour Diesel grows tall, it will require routine trimming and pruning to keep the plants at a manageable size.
