How to Grow Chocolate Mint OG (Mint Chocolate)
Chocolate Mint OG, also known as Mint Chocolate, is a potent, 80% indica with one of the most distinctive flavors around: sweet chocolate and cool mint over citrus and pine. It pairs a high 20-25% THC with a happy, relaxed, munchie-inducing effect, on a compact, high-yielding plant that finishes in a quick 8-9 weeks.
A cross of OG Kush and Granddaddy Purple from the USA, it is a heavily indica-leaning hybrid with a rich, dessert-like character. That lineage shows in the plant: a short, sturdy, resin-soaked structure and a deep, relaxing body feel, wrapped in that unmistakable chocolate-mint aroma.

Climate and Where to Grow It
Chocolate Mint OG is a feminized photoperiod strain, so every seed grows into a flowering female and you control the cycle with light: a long day of around 18 hours through veg, then a switch to 12/12 to trigger flowering. There is no need to sex the plants, which is one reason it suits newer growers.
It does best in a warm, sunny, tropical climate with plenty of light and good airflow. As an 80% indica it stays short and bushy at around 1.5 m, so it fits most tents and plots while still carrying a heavy harvest. Outdoors in the northern hemisphere it is typically ready in October, so it suits regions with a reasonable autumn window.
Keep humidity in check to protect its dense, resinous buds: around 55-60% in veg, nearer 40% in flower, and down to about 30% by harvest. Those tight, chunky colas can trap moisture, so steady airflow and sensible humidity are the keys to a clean finish.
Feeding Schedule (EC Guide)
Chocolate Mint OG is a vigorous, hungry, high-yielding indica, so feed it steadily, but still start low and build up as the plant asks for more. Taper right off for the final flush so the chocolate-mint-and-citrus 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 a quick 8-9 weeks. As an 80% indica, Chocolate Mint OG stays short and bushy while packing on dense, chunky, resin-soaked colas, often with deep purple hints from its Granddaddy Purple parent as the nights cool. A little cold snap late in flower helps bring that colour out.
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 with a ScrOG net so light reaches the lower buds, and harvest when most trichomes have turned cloudy for the fullest, sweetest 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 chocolate-mint 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 chocolate, mint, citrus and pine notes forward and smooths the smoke, which is exactly what this flavourful, resinous strain deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Chocolate Mint OG 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 sweet, chocolate-mint concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Chocolate Mint OG lives up to its name: a rich, sweet chocolate flavor with a cool mint lift, backed by citrus and a fresh pine edge. It is a distinctive, dessert-like taste rather than a simple or gassy one, and a good cure really brings that chocolate-mint character forward in the jar and on the inhale.
Its compact terpene profile is led by caryophyllene, which brings a warm, peppery spice that grounds the sweet chocolate note, with humulene adding an earthy, woody depth. Limonene lifts the profile with a bright citrus note, while pinene gives the fresh, cool pine edge. The chocolate and mint character comes through from this terpene mix and its OG Kush and Granddaddy Purple heritage.
Effects and Best Use
With its high 20-25% THC and 80% indica make-up, Chocolate Mint OG delivers a strong, body-forward experience. It is reported as happy and relaxed, with a cheerful, mood-lifting start that settles into a heavy, comfortable, full-body ease, and it often brings on a pleasant case of the munchies. This is a potent strain, so a little goes a long way, especially if you have a lower tolerance.
That profile makes it an evening strain, best for unwinding at the end of a long day when you have nothing left to do. The combination of serious potency, a standout chocolate-mint flavor and a big, fast yield is exactly why this one is such a rewarding grow.
Common Problems and Pro Tips
The main thing to manage with Chocolate Mint OG is moisture in its dense, chunky buds. That tight indica structure can trap humidity and invite mould or bud rot, so keep humidity low through flower, run good airflow over and under the canopy, and inspect the fattest colas as harvest nears. Its sweet, resinous smell is strong, too, so a carbon filter is worth having indoors.
Its big yield is the other thing to plan for. Those dense colas get heavy, so give the main branches support as they swell, and use a ScrOG net or light low-stress training to open the short, bushy plant and lift the lower buds into the light. Strong, even light over the canopy is what turns its potential into a full harvest.
As a pro tip, let this one finish properly to get the most from its 20-25% THC and its purple colour: follow the trichomes rather than the calendar, and a cool night or two late in flower will deepen the colour. Keep the feed moderate rather than heavy so you don’t mute the chocolate-mint terpenes, run a clean plain-water flush at the end, then dry slowly and cure for three to four weeks.
FAQ
How much THC does Chocolate Mint OG have?
It is a high-THC strain, testing at around 20-25%, which makes it genuinely potent. Combined with its 80% indica genetics, that gives a strong, happy, body-forward effect. If you have a lower tolerance, start with a small amount, because this one hits harder than its sweet flavor might suggest.
Is Chocolate Mint OG an autoflower?
No. Chocolate Mint OG is a feminized 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. Being feminized, every seed grows into a flowering female, so there is no need to sex the plants.
Why is it also called Mint Chocolate?
Chocolate Mint OG and Mint Chocolate are two names for the same strain, both pointing to its signature flavor: sweet chocolate with a cool mint lift. Whichever name you see it under, it is the same OG Kush x Granddaddy Purple indica with that distinctive dessert-like profile.
What does Chocolate Mint OG taste like?
It has a rich, dessert-like flavor: sweet chocolate with a cool mint lift, backed by citrus and a fresh pine edge. Caryophyllene adds a peppery spice that grounds the chocolate, limonene brings the citrus, and pinene the cool pine note, giving it a truly distinctive taste.
How long does Chocolate Mint OG take to flower?
A quick 8-9 weeks once you switch to a 12/12 light cycle. As a mostly indica strain it fills in dense, resinous, often purple 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 Chocolate Mint OG 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, support the dense colas and use a ScrOG net to make the most of a compact, bushy plant.
