Sour Diesel (also known as Sour D) is one of the most famous and appreciated Sativa-dominant strains in the world, with origins dating back to the 1990s. It is a legendary hybrid, often the result of crossing genetics such as Chemdawg and Super Skunk. Its effect provides a cerebral, euphoric, and invigorating high, ideal for daytime consumption, stimulating creativity, focus, and mood. Its potency is high (often 20-25% THC) and its aromatic profile is unmistakable, dominated by intense and pungent notes of diesel fuel and earth, complemented by citrus and sour undertones.

Plant Morphology. Sour Diesel develops a plant with a clear Sativa pattern: tall, with a slender structure and vigorous growth that tends to stretch considerably during flowering. It presents good lateral branching, which, if trained correctly, can support abundant harvests. Its leaves are thinner and light green, which is typical of Sativas. Due to its potential height (it can exceed 2 meters outdoors), it is more suitable for growers with some experience who can manage its large size.

Flower Appearance. Sour Diesel buds are medium to large in size, with a slightly airier structure than Indicas, yet notably dense and frosty. They are covered in a thick layer of glistening trichomes that attest to their high potency. The pistils are long and a vibrant orange color. The aroma of fuel and citrus is potent and pungent. When smoked, the smoke is dense and the flavour of diesel and spices lingers on the palate. Its effect is a stimulating and energetic high that lasts for hours.

Cultivation tips

• What training techniques work best with Sour Diesel?
  Given its tendency to stretch, the use of height control techniques indoors is almost mandatory, such as SCROG (Screen of Green) to force horizontal growth and maximize light space. Apical pruning and LST (Low Stress Training) are very effective.

• What kind of fertilisation does Sour Diesel need?
  It has moderate nutritional needs. Requires a adequate amount of nitrogen in vegetative stage. In flowering, the focus should be on phosphorus and potassium. It is sensitive to over-fertilisation, so a moderate and organic fertilisation regime is recommended.
• How should watering and humidity be for Sour Diesel?
  Irrigation should be regular, allowing the substrate to dry out between cycles. Relative humidity should be maintained low in the flowering phase (ideally 40%), especially due to the structure of its buds, to prevent mould.
• Is it necessary to prune the Sour Diesel plant?
  Yes, it is highly recommended. A clean-up pruning o _lollipopping_. to remove low shoots and branches that do not receive light. Maintenance pruning also helps to maintain good air circulation.
