About the Strain
Sour Diesel, otherwise known as Sour D, or Sour Deez, is a popular cannabis strain, that is widely known for its pungent smell, that defiantly has that fuel-like aroma. Whilst this may put you off, the effects of this strain can be pretty powerful, giving users an uplifting and energising high.
Sour Diesel is a sativa-dominated mix of 60% sativa and 40% indica and is thought to have originated from the strains Super Skunk and Chemdawg 91 (although this is not 100% known for sure). Created in California back in the 1990’s, it is now one of the most popular strains on the market.
Aromas, Flavours and Appearance
This pungent strain, smells of diesel and skunk, with top notes of lemon. The strong aroma and taste of this strain sure packs a punch, for those of you who are looking for a dark, strong, and funky taste.
When smoking Sour Diesel, you will notice the fuel-like taste, as well as earthy, sour, and citrus notes.
Sour Diesel has a typical ‘weed’ look to its buds, which are long and fluffy, with green leaves and subtle orange-pink pistils.
Effects and Usage
The high you get from Sour Diesel comes fast and strong, giving users an energising, uplifting and happy high. It is also said to inspire creativity, as well as give a motivating energy. This is definitely a mood enhancer so one to try if you are experiencing stress, depression, or anxiety. It may also help you with pain and fatigue.
Sour Diesel would be a great strain to try for a ‘wake ‘n bake’ sesh, to get you up and motivated in the morning.
Adverse reactions to this strain include dry mouth (cottonmouth) and eyes.
Sour Diesel is a cannabis strain suited to those who have a little experience, as it can sometimes be a challenging grow. You should also be aware that this strain is particularly pungent, so if you would like to conceal your cannabis growing, it may be difficult to control the aroma from your plants. Investing in an odour eliminator is a great idea.
Sour Diesel loves a sunny and warm environment, but if growing outdoors, then be aware this strain is prone to powdery mildew , so a dry climate would be best. Sour Diesel can grow pretty tall and lanky (being mainly sativa) when grown outside in the optimal climate, produces big yields.
When growing outdoors, you must make sure you have to time to prune and tame your plant, or you may find it getting out of control! Because it flowers a little later, ensure your climate stays warm into April and May (Southern hemisphere) or October and November (Northern hemisphere).
If growing indoors, you will need some strong grow lights and a dry room, with little humidity. Sour Diesel loves a fertile soil, whether growing indoors or outdoors. Be sure to prune your plant when growing indoors as it can grow quickly.
Also remember to keep an eye on the humidity levels of your plant. This strain should be kept at around 65-70% humidity during the vegetative stage and lower this by 10-15% in the flowering stage. Drop the humidity down an extra 5% during the nights of the flowering stage.
Indoors or Outdoors?
Whilst you can certainly grow Sour Diesel indoors, a small grow space may not be enough, as this strain can quickly take off. Consider growing outdoors or in a greenhouse. It has quite late harvesting time when grown outdoors, but you will see larger yields. Give this plant room to grow!
Flowering, Yield and Harvest
Sour Diesel typically takes around 10 to 11 weeks to flower, and you can expect to see around 510 to 600 grams for every plant when grown outdoors. When growing indoors you could see 475 to 525 grams per square metre.
When growing outside, Sour Diesel will be ready to harvest in mid-April in the Southern hemisphere, or early-to-mid October in the Northern hemisphere.

This strain loves its food! Make sure it has all the nutrients it needs, particularly in the flowering stage, to help the buds become dense. Using soil is slightly more forgiving if you overdo it with the nutrients. If you are using a good quality soil, it will have a lot of nutrients in there already, so there is no need to add any during the seedling stage.
During the vegetative phase you will need to give your plant twice as much nitrogen as phosphorus, and three times more nitrogen than potassium. The nutrient ratios to look for on the bottle will be either 6-3-2 or 18-9-6. You should also add in some sulphur, magnesium, and calcium.
During the flowering stage, change the ratio so you are using up to three times more phosphorus than nitrogen and potassium. Also continue to add in secondary nutrients such as iron, copper, and manganese. Stop using nutrients and fertilisers 1 to 2 weeks before you harvest, to clean out the plant of any chemical taste.
Other Growing Tips
Sour Diesel can be a little tricky to grow, particularly if growing indoors. You may want to try the Low-Stress Training (LST) technique to direct more light to the lower buds. This should help to increase your yield.
Feminised seeds ensure that the plant you will grow is female. Only the female plants can make the flowers and buds that produce weed (not male plants). By buying feminised seeds you can be sure that you have the best chances for a good harvest!
