Overview
Sour Diesel Auto is a cross between a ruderalis, otherwise known as an auto-flowering cannabis plant, and the highly esteemed strain, Sour Diesel. Together these parents gave birth to a fast-finishing, Sativa-dominant plant. Due to its short life cycle, you can have two harvests during the year that combine for an abundance of high-quality, resinous, diesel-smelling buds.
Strain Effects
Because of the ruderalis genetics, the THC levels aren’t as high as the parents, but still, give you a great potency with THC levels reaching around 16%. So, the soaring tripping stone is still the main feeling, yet it is a little more balanced in this auto-flowering version. Customers love to smoke this strain early in the day because of its cerebral hit and uplifting effects that can keep you energized for hours. Also, its lineage gives the strain a bit of a physical buzz. There’s definitely a dominance of a happy, energized feeling, but it’s supported and balanced by a deep sense of calm.
Growing info
Sour Diesel Auto has a fast seed-to harvest timeline of 60 to 70 days, but the plant still manages to yield generously, and it produces a potency that its parents would be proud of. When you grow indoors, the plants maintain a short height of 60 to 80 cm and can generate yields of 300 grams per M2. You also have the choice to grow this strain outdoors because it has a high resistance to mold and fungus. Outdoors, the plants are usually taller but rarely reach heights of 100 cm or more. Also, outdoor yields can bring in 400 grams per M2.
Appearance and Aroma
This auto-flowering plant stays true to its ruderalis genetics in terms of its appearance. The plants are short and bushy but showcase big, lush buds. Also, its gorgeous nugs shine bright with crystals and long orange hairs.
As for the aroma, it’s very similar to its name with gassy, diesel-like smells, and noticeable lemony citrus hints. During the later stages of flowering, this aroma becomes powerful. However, it’s not to the point of being overwhelming.
MSNL Editors Verdict
The remarkable reputation of Sour D is undeniable. So its auto-flowering version is an obvious choice for fans who love the idea of a speedy growth cycle with a harvest that’s ready within months of planting the seeds. In addition, this strain has a great taste, possibly an even better smell, and a favorite among many smokers we know.
THC CONTENT | 15%-18% | |
FLOWERING TIME | 8-10 WEEKS | |
TYPE / OUTDOOR | INDOOR/OUTDOOR | |
OUTDOOR HARVEST | JULY+SEPTEMBER | |
PLANT HEIGHT | SHORT 60-100cm | |

The smoke offers a sour lemon and slightly herbal taste. Since the diesel flavour mixes so well with the sour candy taste, it makes a delicious and tasty treat for all the senses involved. Also, there are additional earthy skunk flavours from the ruderalis, although subtle, they are still present and add nicely to the mix. Lastly, the Sour Diesel Auto strain provides a clean and smooth smoke, making it gentle on the throat with each hit.

"A fantastic free surprise."
Review by Rob
Bonus seed from Msnl, free autoflowering is the best. First time growing Sour Diesel, I had only ever heard the name. Very pungent in a good way, fresh and fast to germinate, big buds gassy and fun. Cheers and what a great surprise.

"Took a beating, and them some!"
Review by mescal
Got this as a freebie with my order. New to DWC and doing all organic lead to many mistakes. This girl took a beating from pH drift and yellowing tips, and she nearly died in veg after an ozone device was left running and wiped all but 2 seedlings in the tent. After nursing her back to health and using LST soft rubber ties to make a SCROG, this beauty was SO leafy dense, light could not get through the canopy. Even took clones off her that, true to the Auto story, went straight into flower even under 18 hrs photo period. Clone in DWC came out a little under half the size of the mother. Worth taking clones to increase your yield, just don't expect a full size daughter. Need to really pump up the clones with DWC to get any decent size, soil clones just became buds on a little stick! Very sweet, and fuelly aroma. Would grow this again!

"1st time grower"
Review by Patrick
Pleasantly surprised with the quality of this bud considering the problems I had in my indoor grow room as a newbie (heat, humidity, exhaust, light inconsistencies). Still produced quality smoke. A little stunted considering all the issues. Can't wait to see what happens once I get some skills. Would definitely order this strain (sent free with my order). Thanks MSNL for turning me on to autos! Great user friendly website!

"Fast and potent Diesel"
Review by Anthony
First off, let me say that I have tried a lot of diesel strains in the last 20+ years, and I am not a diesel fan at all. But, I got 10 of these seeds on a super great deal, because of the price only. So, after planting 10 seeds, 63 days latter, I harvested 9 monsters that grew super quick and easy, quite big, and very potent(even without being cured yet.......it was suppose to just be a sample. But, it taste so good and strong now, that I'm not sure if it will make it past a light cure.).... WOW.... I am now a Sour Diesel Auto, fan of MSNL.

"Fast Delivery"
Review by Chiddy Bang
Placed the order for 5 Sour Diesel Auto Fem seeds which were on BOGOF offer on 27th January, 2018. Received my order in 10 days a super stealthy way on 7th February, 2018. Got 10 seeds of SDAF and also 5 regular seeds of Pure Power Plant as freebies. Super Happy! Unfortunately I can't grow them till March/April as I have to shift to a new house. Will update asap.

"Gross taste"
Review by Miranda
The high of Sour D is always awesome, but can't get past the taste. It's so gassy! It's really smooth on the throat though, which is nice and might make up for the pungent taste.

"Great for tasty treats"
Review by Edible Jane
Sour D is always a great smoke, but it's great for turning into concentrates or edibles too. Lemony dishes work well with the already citrus taste, makes for a great lemon cake in the AM.

"Makes my mouth water"
Review by Bongy Bob
Huge crystals, tons of hairs, and big lush buds that you wouldn't necessarily expect from a sativa. Sour D is a top choice for many, and one never has to wonder why.

"A classic sativa strain"
Review by Sally Sativa
A love all sativa plants, but this one is by far my fave. Keeps you up, energized, and always ready to smoke some more - which is always a great quality in any bag.

"Wake n bake strain"
Review by Mikey
This is a great strain for wake n bakes. It doesn't give you serious couch lock, along with a good cup of coffee, you'll still be able to start your day and get stuff done.

"Nice balanced high, pungent smell"
Review by Molly
Sour Diesel is the right name for this weed - the lemony/gassy smells hit me in the face as soon as I lit my bowl. It gives a nice balanced high, making me happy and relaxed, but still had energy to get stuff done.
