How to Grow Lamb’s Bread
Lamb’s Bread, also written Lambs Bread, is a classic, almost pure sativa feminized strain from Jamaican landrace genetics. It is an 80/20 plant with a moderate 16-21% THC, a citrus, herbal and woody flavor with a sweet edge, and an energetic, uplifted and happy effect. Tall, vigorous and famously upbeat, it is a reggae-era classic that rewards a little patience with a soaring, daytime character.
This is a feminized photoperiod strain that can reach around 2 m and flowers in 8 to 10 weeks once you switch it to bloom. Every seed grows into a flowering female, so there is no need to identify the sex or remove males, which keeps the grow simple from start to finish. Its Jamaican sativa heritage gives it a tall, airy structure, a bright citrus-herbal profile and an energetic, soaring character.

Growing a Feminized Photoperiod Strain
Lamb’s Bread is a photoperiod strain, so it flowers in response to the light cycle rather than on age. You grow it under a long day of around 18 hours of light while it builds size and structure, then switch to a 12/12 light schedule to trigger flowering, which runs 8 to 10 weeks from the flip to harvest. Because the seeds are feminized, every plant comes up female and goes on to flower, so you never have to check the sex or cull males.
That control over the light cycle matters with a near-pure sativa like this. It stretches hard after the flip and can reach around 2 m, so many growers flip it earlier to keep the final height in check. Give it an open canopy and a little low-stress training to manage that stretch and spread the light down the plant, and plan for its tall, airy frame.
Climate and Where to Grow It
Lamb’s Bread does best in a warm, tropical or Mediterranean-style climate with plenty of sun, steady warmth and good airflow, in keeping with its Jamaican roots. It is a vigorous, sun-loving plant, and outdoors it suits a long, warm season with room to grow tall, finishing by around October.
It performs well indoors and out, but it really stretches its legs outdoors. Indoors it returns a moderate 400 g/m² in a well-managed tent, while outdoors a healthy plant with room and sun can give a huge 600-1000 g. As a tall, near-pure sativa of around 2 m it needs real headroom, so give it space and support, and keep the canopy open so light and air reach the lower buds.
Keep humidity under control through flowering to protect the airy buds: around 55-60% in early bloom, nearer 40-45% as the flowers fill out, and lower toward harvest. A tall sativa with long, open buds benefits from steady airflow, which keeps the finish clean. Aim for daytime temperatures around 72-82°F (22-28°C), which this warm-climate plant enjoys.
Feeding Schedule (EC Guide)
Lamb’s Bread is a steady feeder, and it pays to build nutrients up gradually and let the plant set the pace. Feed it through veg and flowering, then taper off for the final flush so the citrus-and-herbal flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed while roots establish |
| Vegetative growth | 0.8-1.2 | Raise nitrogen as the plant builds size |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you switch Lamb’s Bread to a 12/12 light schedule it flowers in 8 to 10 weeks, fairly quick for a near-pure sativa. It fills out with longer, airier, spear-shaped colas rather than the dense chunks of an indica, so it rewards good light and airflow right down the plant. Grown outdoors in a warm climate it is typically ready to harvest around October, once the trichomes have turned mostly cloudy.
Yields are moderate indoors at around 400 g/m², and very large outdoors at 600-1000 g per plant with room and sun. Give it a little training so the lower buds get light, feed it steadily through bloom, and harvest when most of the trichomes have turned cloudy for the fullest citrus-and-herbal flavor and the brightest of its energetic effect.
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 protects both the aroma and the resin, and it matters on any plant that buds can stay damp in the middle while the outside dries, so keep the dry gentle and even.
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 out the citrus, herbal and woody notes and smooths the smoke, which matters on a classic landrace sativa where a clean, bright flavor is a big part of the appeal.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Lamb’s Bread carries a useful amount of resin, so its trim works well for dry sift, bubble hash or rosin. It makes for a bright, citrus-and-herbal concentrate run from material most growers would otherwise throw away, a nice bonus from a tall, high-yielding sativa.
Flavor and Terpenes
Lamb’s Bread has a bright, grassy flavor: a fresh citrus and herbal lift over a woody, earthy base with a sweet edge. It is a classic, uplifting sativa profile rather than a heavy or gassy one, and a good cure really brings that citrus-and-herbal character forward in the jar and on the inhale.
Its terpene profile shapes that character. Alpha-pinene drives a fresh, sharp pine note that lifts the whole profile, while delta-3-carene adds to the crisp, woody sharpness. Caryophyllene brings a warm, peppery spice, and terpineol rounds it out with a soft, herbal-woody note, with the bright citrus side riding on that fresh, piney lift. Together they frame the citrus, herbal and woody character Lamb’s Bread is known for.
Effects and Best Use
With its moderate 16-21% THC and near-pure 80% sativa make-up, Lamb’s Bread delivers a bright, soaring experience. It is reported as energetic, uplifted and happy, so it leans firmly toward an upbeat, clear-headed daytime high, the kind of lively lift that made it famous. Because the THC runs into the high teens and low twenties, it is worth starting with a moderate amount if you have a lower tolerance.
That energetic, uplifted profile makes it a great daytime strain, well suited to activity, creative work or socialising with a clear, cheerful lift. The combination of a classic landrace pedigree, a big outdoor yield and a bright citrus-herbal flavor, all with an upbeat, energetic effect, is exactly why it has stayed a classic.
Common Problems and Pro Tips
The main thing to manage with Lamb’s Bread is its height and sativa stretch. It gains serious height after the flip and can reach around 2 m, so top or train it in veg, consider flipping a little earlier, and be ready to support the taller, spear-shaped colas. Keep the air moving around its open, airy buds so the finish stays clean.
Because it grows tall and lanky, train it to even things out. A little low-stress training or a light topping in veg opens the canopy, turns one dominant cola into several and keeps the height manageable, which suits its airy sativa frame. Give it a sturdy frame or stakes to lean on, especially outdoors where it can get very big.
As a pro tip, give it room: Lamb’s Bread rewards a big container and full sun outdoors, where its huge yield potential really shows. Finish with a clean plain-water flush and a full three to four week cure to bring that bright, citrus-herbal flavor to its best.
FAQ
Is Lamb’s Bread a feminized strain?
Yes. Lamb’s Bread is a feminized photoperiod strain, so every seed grows into a flowering female and you never have to identify the sex or remove males. You grow it under long days, then switch to a 12/12 light schedule to start flowering. That keeps the whole crop productive and makes the grow more straightforward, which is part of why it suits first-time growers so well.
How much THC does Lamb’s Bread have?
Lamb’s Bread has a moderate THC of around 16-21%. Combined with its near-pure 80% sativa genetics, the result is an energetic, uplifted and happy effect that leans firmly toward daytime use. Because it still runs into the low twenties at the top end, it is worth starting with a moderate amount if your tolerance is lower, then adjusting to suit you.
How long does Lamb’s Bread take to flower?
Lamb’s Bread flowers in about 8 to 10 weeks once you switch it to a 12/12 light schedule, which is fairly quick for a near-pure sativa. As a photoperiod strain you also control how long it vegetates beforehand, which helps manage its considerable stretch. Outdoors in a warm climate it is usually ready to harvest around October.
What does Lamb’s Bread taste like?
Lamb’s Bread has a bright, grassy flavor: a fresh citrus and herbal lift over a woody, earthy base with a sweet edge. Alpha-pinene drives the fresh pine, delta-3-carene the crisp woody sharpness, caryophyllene a peppery spice, and terpineol a soft herbal note. A proper three to four week cure really brings that citrus-and-herbal character forward.
How much does Lamb’s Bread yield?
Lamb’s Bread gives a moderate 400 g/m² indoors and a very large 600-1000 g per plant outdoors with room and full sun. Results depend on light, pot size and canopy health, so give it headroom for its height, train it to manage its stretch, and give outdoor plants a big container and plenty of space to reach those big numbers.
Is Lamb’s Bread good for beginners?
Yes. Lamb’s Bread is a beginner-friendly strain in that it is feminized so there is no sexing, and forgiving as long as you keep the air moving. The main things to plan for are its tall sativa stretch and long, airy structure, so a little height management and light training are all it really asks of a first-time grower.
