How to Grow Chemdog Regular: Classic Diesel Indica
Chemdog Regular is a piece of cannabis history: a clone-only selection of the legendary Chem 91 phenotype, offered as regular seeds. This mostly indica strain pairs a pungent citrus, fruity and diesel flavor with a high 17-24% THC, and a focused, happy, relaxed effect that works for day or evening on a sturdy, high-yielding plant.
Also spelled Chemdawg, this is one of the most influential strains in modern cannabis, the parent behind countless diesel and OG lines. As a 60% indica / 40% sativa, it brings a strong body feel with a clear, focused head. Its pungent gassy character comes from the same genetics that gave rise to Sour Diesel, OG Kush and Stardawg.

Working With Regular Seeds
Regular seeds are not feminized, so they grow into roughly half male and half female plants. Unless you are breeding or making your own seeds, you grow them out, identify the sex once they show their pre-flowers, and remove the males before they can pollinate your females. Only the females produce the smokable, resinous buds you are after.
That extra step is exactly why breeders prize a clone-only classic like Chemdog: growing it from regular seed is a chance to hunt for your own keeper phenotype and work with the authentic Chem 91 line. It is a photoperiod plant, so you grow it under a long day of around 18 hours, then switch to a 12/12 cycle to trigger flowering.
Climate and Where to Grow It
Chemdog Regular does well in a temperate climate with plenty of light and good airflow. As a 60% indica it has a sturdy, branchy structure and stays a manageable 1.5 m, so it fits most tents and plots. Outdoors in the northern hemisphere it is typically ready to harvest in October, so it suits regions with a reasonable autumn window.
Indoors, aim for daytime temperatures around 68-80°F (20-27°C) with nights a little cooler, and keep airflow steady over and under the canopy. It prefers lower humidity to protect its dense, resinous, pungent buds: around 55-60% in veg, nearer 40% in flower, and down to about 30% by harvest, which keeps mould and bud rot away.
Feeding Schedule (EC Guide)
Chemdog is a vigorous, hungry plant that rewards steady feeding, but still start low and build up as it asks for more. Taper right off for the final flush so that pungent citrus-and-diesel flavor comes through clean and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8-1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the resinous buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs 8-10 weeks. As a 60% indica, Chemdog stays fairly compact and bushy, filling in dense, resin-soaked, pungent colas. The buds carry the heavy gassy aroma the line is famous for, so good airflow and a carbon filter are worth having in an indoor space.
Yields are strong: around 400-600 g/m² indoors and 400-500 g per plant outdoors, depending on light, pot size and canopy health. Give the dense colas light support as they fatten, keep the canopy open so light reaches the lower buds, and harvest when most trichomes have turned cloudy for the fullest, most pungent expression.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry stops the dense, resinous buds staying damp in the middle while the outside dries out, which protects both the gassy aroma and the heavy trichome coat.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings the citrus, fruity and diesel notes forward and smooths out this classic, pungent smoke, which is exactly what a strain with Chemdog’s reputation deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Chemdog Regular is a very resinous, high-trichome plant, so its trim is excellent for making dry sift, bubble hash or rosin. That gives you a bonus run of pungent, citrus-diesel concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Chemdog Regular has a bold, pungent profile: a strong diesel punch lifted by citrus and a sweet, fruity edge. It is a gassy, mouth-watering flavor rather than a light or floral one, and a good cure really rounds out that citrus-and-diesel character in the jar and on the inhale.
Its compact terpene profile is built on four players. Caryophyllene drives the warm, peppery spice behind the diesel punch, limonene brings the bright citrus lift, alpha-pinene adds a crisp, fresh pine note, and humulene rounds it out with an earthy, hoppy depth. Together they give Chemdog its signature gassy-citrus aroma, with the diesel character reinforced by its Chem 91 and diesel heritage.
Effects and Best Use
With its high 17-24% THC and 60% indica make-up, Chemdog Regular delivers a strong but balanced experience. It is reported as focused, happy and relaxed: a clear, cheerful, content head paired with an easy, comfortable indica body, which keeps you engaged rather than couch-locked. That balance is why it works well for both day and evening use.
It is a versatile strain for anyone who wants real potency with a clear head: good for getting things done, for socialising, or for unwinding at the end of the day. The combination of iconic diesel genetics, a pungent citrus-gas flavor and a strong, focused effect is exactly why Chemdog remains such a sought-after name.
Common Problems and Pro Tips
The first thing to plan for is that these are regular seeds: check for sex as soon as pre-flowers appear and remove the males promptly unless you are breeding, so they don’t pollinate your females. If you are hunting a keeper, grow out a few plants and select the one with the best Chem 91 structure, aroma and resin before you commit.
Its pungency is the other practical point. Chemdog is one of the gassiest strains around, so an indoor grow really benefits from a good carbon filter and strong airflow to manage the smell and keep the dense buds healthy. Keep humidity low through flower and inspect the fattest colas as harvest nears to stay ahead of mould in that tight bud structure.
As a pro tip, protect the citrus-diesel flavor and the resin: keep the feed moderate rather than heavy so you don’t mute the terpenes, and run a clean plain-water flush in the final one to two weeks. A ScrOG net or light low-stress training opens the bushy plant up for a bigger harvest, then follow the trichomes rather than the calendar and cure for three to four weeks.
FAQ
Are Chemdog Regular seeds feminized?
No. These are regular seeds, so they grow into both male and female plants, roughly half and half. Unless you are breeding, you identify the sex once pre-flowers show and remove the males before they pollinate your females, since only the females produce the resinous, smokable buds you want.
How much THC does Chemdog Regular have?
It is a high-THC strain, testing at around 17-24%. That gives it a strong but balanced effect rather than an overwhelming one. Combined with its 60% indica genetics, it stays potent but clear-headed, which is why it works well for both daytime focus and evening relaxation.
Is Chemdog Regular an autoflower?
No. It is a photoperiod strain, so it flowers on a light change rather than on age. You grow it under long days, then switch to a 12/12 light cycle to start flowering. As a clone-only Chem 91 line offered as regular seed, that flowering stage runs around 8-10 weeks.
What does Chemdog Regular taste like?
It has a bold, pungent flavor: a strong diesel punch lifted by citrus and a sweet, fruity edge. Caryophyllene drives the peppery diesel note and limonene the bright citrus, while alpha-pinene adds a crisp pine freshness and humulene a touch of earthy, hoppy depth underneath.
How long does Chemdog Regular take to flower?
Around 8-10 weeks once you switch to a 12/12 light cycle. As a mostly indica strain it fills in dense, resinous, pungent colas over that window. Outdoors in the northern hemisphere, plants are typically ready to harvest in October, so it suits regions with a reasonable autumn.
How much does Chemdog Regular yield?
Yields are strong: around 400-600 g/m² indoors and 400-500 g per plant outdoors. Those numbers depend on light, pot size and canopy health, so give it strong light, an even canopy and good airflow, and use a ScrOG net to make the most of its branchy structure.
