Overview
The genetic parent of strains such as OG Kush and Sour Diesel, Chemdog offers the highest pedigree in marijuana lineage. Prized by many as their go to strain when they want something strong and tasty, it excels on both points.
Strain Effects
The high comes on strong yet is not over powering. The sativa dominance gives the classic head buzz with the indica genes balancing it with a calming body stone. An all round legendary strain with excellent strength, yield and medicinal properties.
The smoke is quite uplifting without being trippy. A resonant body buzz comes on quite soon after the initial head hit meaning that you can feel quite fuzzy, yet still with enough clarity to be able to get some things done if you need to.
Growing info
A flowering time of 8-10 weeks and massive yield of around 500g/m2 + makes this strain an excellent choice for cash croppers. The stretchy shape and multiple dense bud sites also mean it thrives in a SCROG setup, helping maximise yields. THC levels are seriously high, 21%+. Later in the flowering process buds can be seen glistening with THC crystals, making Chemdog excellent for hash or oil production.
MSNL Editors Verdict
As far as sativas go this is one of our favourites. Its fast enough that it can be grown outdoors in most temperate and warm climates and the uplifting high it gives is a real booster. The flavour is delicious and the yields are massive. The one slight drawback is that it does not do well in wet or humid conditions so if moisture is a problem in your grow area, be aware.
THC CONTENT | 19%-22% | |
FLOWERING TIME | 8-10 WEEKS | |
TYPE / OUTDOOR | INDOOR/OUTDOOR | |
OUTDOOR HARVEST | EARLY OCTOBER | |
PLANT HEIGHT | MEDIUM 100cm-180cm | |
YIELD | 400-500 g/m2 |
When you open a jar of Chemdog it will stink up the whole place very quickly. The characteristic astringent fuel smell that this strain has become famous for is instantly recognisable There is also a definite undertone of a more earthy kush flavour that goes very well with the chemical notes to even out the taste, meaning that that it has a more unique flavour than NYC Diesel.

"Great "
Review by Troop
Seeds that I didn’t mess up all germinated quickly. loving the growth so far, doesn’t look like I have a million different phenotypes like with some seed companies! All similar growth patterns which I truly appreciate! Sucks when you get a bag of 10 seeds and have 4 or more different phenotypes at the end of harvest. 2nd order and they have all made it to Cali!! Love this fucking company! Just wish they get more exotic strains!

"Top Shelf"
Review by vlad
Grew this along with Blue Dream and Girl Scout Cookies, both fine strains but Chemdog smoked em both. You'll know you got a keeper when it reeks as a seedling. A decent yielder with a strong all around buzz but it's the smell and taste that sometimes makes me wonder why I bother growing anything else. Funky Savoury Chemical Stank! Open a jar and gas the place up! One of the greatest strains of all time.

"AMAZING!!"
Review by GreenThumbJim
One the best strains by MSNL, can't believe it's so cheap! The indica phenotype is better of the two that came through. I recommend 9 weeks flower in soil for maximum flavour. Super strong diesel smell and taste with a hint of lemony skunk and earthy spice undertones. Definitely a keeper!

"Chemdog is world-famous, for good reason"
Review by Dog Smoker
Chemdog is such a classic and iconic strain, and it's good to be able to find it on its own and not cross-strained with anything, like it usually is. Just pure Dog,with pure skunky smell.

"NICE HIGH, VERY TASTY"
Review by mastergrow54
Quick hitter. 2 tokes, and you'll know it's with you! Very easy to grow, and responds well to pruning. Decent THC presence. Grows about 4' under 400w. Good SOG candidate. Very good yield, especially when topped a couple times. On a scale of 1-10, I would give it an overall 8.5.

"GREAT YEILD"
Review by yt1057
I grew 2 of these Chemdog seeds outdoors this summer. I harvested on Sept 30th and got 3.3 lbs of killer smoke from these 2 plants. My friends all want to smoke my smoke.

"Definitely one for the SCROGger!"
Review by Gordon
I took the recommendation of the folks at MS-NL, and set this up as a single plant SCROG, and I'm glad I did. This thing grew like a beast, and would certainly overgrow a 4x4 grow tent if not properly trained. I let it flower for a full ten weeks, and was definitely worth the wait. This Chemdog is a huge yielder! The only thing I've grown in the last year that comes close to this is Blue Dream (also available at MS-NL). I believe the Chemdog is much stronger, however. Since the buds are so huge, it makes trimming easier, but be prepared to clean your trimmers every 5 minutes, because the trichome production in this strain is most impressive. The high is the real "highlight", though. There's a reason this strain is so steeped in cannabis lore. It is a mad heavy hitter, and while not as crushing as some heavy indicas, it just keeps soaring. I don't recommend this strain for daytime medicating, simply because it's too strong. Unless you plan on watching TV all day, in which case it's perfect. Strains I like for the daytime include Blue Dream, and Chocolope, both of which are available feminized on this website. As for the Chemdog, two big gorilla thumbs up!
