How to Grow Harlequin Kimbo Kush Fast Version CBD
Harlequin Kimbo Kush Fast Version CBD is a fast-flowering, high-CBD feminized strain prized for its gentle, clear-headed character and bright lemon-citrus flavor. It carries 11–15% CBD with a low 3–6% THC, a citrus, earthy and lemon taste, and a focused, happy, relaxed effect on a compact, quick-finishing plant.
Bred from Kimbo Kush crossed with Harlequin and a ruderalis line for its fast-flowering trait, this is a 60% indica, 40% sativa CBD strain. The Harlequin side brings the high-CBD, clear-headed character (from Colombian Gold, Thai and Swiss Sativa), while Kimbo Kush (descended from OG Kush) adds indica weight and stable, resinous structure on a quicker cycle.

Growing Fast Version Seeds
A Fast Version is not an autoflower. Although this strain carries a touch of fast-flowering genetics in its background, it is still a photoperiod plant, so it flowers on a light change rather than purely on age. You grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 cycle to trigger flowering, exactly as you would with any fast-flowering strain.
What you gain is speed: once you flip, it finishes its bloom quickly, in around 6–8 weeks. Being feminized, every seed grows into a flowering female, so there is no need to sex the plants. Grow it like any THC strain: the high-CBD, low-THC result comes from its genetics, not from any change to how you cultivate it.
Climate and Where to Grow It
Harlequin Kimbo Kush Fast Version CBD does best in a temperate climate with plenty of light and good airflow. It is a hardy, adaptable plant that performs both outdoors in a warm season and in a controlled indoor tent, staying compact at around 1.5 m, so it fits most spaces without demanding a tall room.
Outdoors it rewards a good spot with 500–600 g per plant, while indoors it is a more modest producer at 300–350 g/m², which is typical for a high-CBD strain where the cannabinoid profile is the point rather than sheer bulk. Those numbers depend on light, pot size and canopy health, so give it good conditions through its quick cycle.
Indoors, aim for daytime temperatures around 68–80°F (20–27°C) with nights a little cooler, and keep airflow steady. It prefers lower humidity: around 55–60% in veg, nearer 40% in flower and down to 30% by harvest, which protects its resinous, CBD-rich buds from mould over the short bloom.
Feeding Schedule (EC Guide)
This is a compact, resinous plant that finishes fast, so feed it steadily but without overdoing it. Start low, build up as the plant asks for more, and taper right off for the final flush so the citrus-and-lemon 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 6–8 weeks, faster than a standard photoperiod strain. As a 60% indica it stays compact and bushy, filling in dense, resinous buds. With a high-CBD strain, harvest timing is about catching the buds at peak resin while the CBD is fully developed.
Give the colas light support as they fatten, and keep the canopy open so light reaches the lower flowers. Harvest when most trichomes have turned cloudy for the fullest expression, and run a short plain-water flush in the last week or two before you cut the plant down.
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 citrus aroma and the resin.
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 brings the citrus, lemon and earthy notes forward and smooths the smoke, which is exactly what this low-THC, CBD-rich strain deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. This is a resinous, CBD-rich plant, so the trim is excellent for making CBD-rich dry sift, bubble hash or rosin, giving you a bonus run of citrusy, low-THC concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Harlequin Kimbo Kush Fast Version CBD has a bright, refreshing profile: a zesty lemon-citrus lift over an earthy, kush-like base. It is a clean, mouth-watering taste rather than a heavy or dark one, pairing the Harlequin citrus with the earthy weight of its Kimbo Kush side in the cured flower.
Its terpene profile is compact, led by caryophyllene for an earthy, peppery kush backbone and terpineol for a soft, lemony-floral note, with pinene bringing a fresh, clean top, linalool a gentle floral touch and nerolidol a subtle woody depth. The bright lemon-citrus character comes through from the Harlequin heritage and those terpenes rather than from an added citrus terpene.
Effects and Best Use
With its high-CBD, low-THC make-up, Harlequin Kimbo Kush Fast Version CBD offers a gentle, mostly clear-headed experience rather than a strong high. It is reported as focused, happy and relaxed, pairing a clear, functional mindset from the Harlequin side with a mild, comfortable body ease from Kimbo Kush, while the low THC keeps it mellow and non-overwhelming.
That makes it a versatile choice for anyone who wants the flavor and ritual of cannabis with a CBD-forward, low-key character instead of a heavy buzz. The bright lemon flavor, the fast, easy grow and the reliable, consistent CBD content are exactly why growers reach for this strain.
Common Problems and Pro Tips
The main thing to understand with this strain is that you grow it like any other Fast Version; the high CBD and low THC come from its genetics, not from harvesting early or changing your technique. Resist the temptation to pull it before the resin is ready, since an early harvest just gives you weaker, less flavourful buds with less developed CBD.
Its low indoor yield and short cycle are the practical things to plan for. Because it is a compact, CBD-focused plant on a quick 6–8 week bloom, make every bud count: give it good light over the canopy, keep humidity low late in flower to protect the resinous buds, and use a ScrOG net or gentle training to open the plant up and lift the harvest.
As a pro tip, protect the lemon-citrus flavor and the resin where the CBD sits: keep the feed moderate rather than heavy, since overfeeding can mute the terpenes, and give it a clean plain-water flush in the final one to two weeks. Follow the trichomes rather than the calendar at the end, then dry slowly and cure for three to four weeks for the smoothest smoke.
FAQ
How much CBD does Harlequin Kimbo Kush Fast Version CBD have?
It is a high-CBD strain, carrying around 11–15% CBD with a low 3–6% THC. That balance makes it CBD-forward and only mildly psychoactive, so it delivers the citrus flavor and character of cannabis with a gentle, mostly clear-headed feel rather than the strong high of a high-THC strain.
Is Harlequin Kimbo Kush Fast Version CBD an autoflower?
No. Despite the fast-flowering genetics in its background, it is a photoperiod plant, so it flowers on a light change rather than on age. You grow it under long days, then flip to a 12/12 cycle to start bloom. What it gives you is a faster finish, around 6–8 weeks, not autoflowering behaviour.
Will it get you high?
Only mildly. With THC at a low 3–6% and CBD at 11–15%, it stays gentle and mostly clear-headed rather than strongly intoxicating. You can expect a focused, happy, relaxed feel with a comfortable body ease, which keeps it mellow and easy to enjoy for day or evening use.
What does it taste like?
It has a bright, refreshing flavor: a zesty lemon-citrus lift over an earthy, kush-like base. Caryophyllene drives the earthy, peppery kush note, terpineol adds a soft lemony-floral touch, and the bright citrus comes through from its Harlequin heritage rather than from a single dominant citrus terpene.
How long does it take to flower?
A quick 6–8 weeks once you switch to a 12/12 light cycle, faster than a standard photoperiod strain. It is a Fast Version, so it blooms on the light change rather than on age but finishes sooner, filling in dense, resinous, CBD-rich buds through that short flowering window.
How much does it yield?
Indoors it is a modest producer at 300–350 g/m², typical for a high-CBD strain, while outdoors it gives 500–600 g per plant. Those numbers depend on light, pot size and canopy health, so give it good conditions, train it to open the canopy, and feed it steadily through its short cycle.
