Forbidden Fruit is a Blimburn Seeds indica-dominant hybrid prized for its exquisite flavor and high potency. From Cherry Pie x Tangie, it blends sweet cherry and bright citrus into a fruity, lemon-and-pine profile, backed by a strong 23-26% THC. It stays compact indoors yet yields big outdoors, with a relaxing, euphoric effect that suits growers of all levels.
This is a photoperiod feminized strain, so it flowers when you shorten the light cycle. The figures below are Blimburn breeder values; check your own pack for the exact numbers.

What Makes Forbidden Fruit Worth Growing
Flavor and potency are the draw. The Cherry Pie and Tangie parents give Forbidden Fruit a rich, layered taste of sweet cherry, bright lemon, and pine, and at 23-26% THC it backs that flavor with real strength. For a connoisseur strain that still grows easily, it is a standout.
It is also practical. Indoors it stays compact at around 1.2 m, easy to fit in a tent, while outdoors it becomes a big producer, up to 700-900 g per plant. The effect is euphoric and happy before settling into relaxation, a balanced lean toward the body from its indica-dominant genetics. It suits all skill levels, from a confident beginner to a seasoned grower.
Is Forbidden Fruit Indica or Sativa?
Forbidden Fruit is indica dominant, listed at 70% indica and 30% sativa. The indica side leads.
In the plant, that means a compact, sturdy, resinous structure, easy to keep in a tent. In the high, the effect leans relaxing and body-focused, with a euphoric, happy lift from the Tangie side keeping it from being purely sedating. It is a late-day and evening strain that still has some brightness.
Flowering Time and Total Grow Time
Because Forbidden Fruit is a photoperiod strain, two timing numbers matter, and they are not the same.
- Flowering time: 8-10 weeks. This is the bloom stage, and it starts only when you switch the lights to 12/12 indoors, or the outdoor days shorten in late summer.
- Total grow time (seed to harvest): flowering plus your veg period. Veg length is yours to set, so a typical indoor run from seed lands around 12-16 weeks depending on how long you veg.
The practical point is that the 8-10 week figure is the flowering window, not the whole grow. You decide the veg length, and that is the main lever for final plant size.
Does Forbidden Fruit Need a 12/12 Light Cycle?
Yes. Forbidden Fruit is a photoperiod strain, so indoors it needs a 12/12 light cycle to start flowering. You veg it under a longer schedule, usually 18/6, then switch to 12 hours on and 12 off to trigger bloom.
Outdoors the season does this for you, with flowering starting as the days shorten in late summer. This is the key difference from an autoflower, which blooms on age no matter the light schedule.
Forbidden Fruit Grow Timeline, Week by Week
Veg length is up to you, so the flowering weeks are the fixed part. Adjust the start to suit your space.
- Weeks 1-2: germination and seedling. The taproot and first leaves establish. Keep water light and conditions stable.
- Weeks 3-5: vegetative growth. The plant builds a compact, bushy frame. Top it and start LST or a SCROG net to spread the canopy.
- Flip to 12/12: switch the light cycle at about two thirds of your target height, to leave room for the stretch.
- Flower weeks 1-3: the stretch and first pistils.
- Flower weeks 4-8: dense, resinous buds form and the cherry, lemon, and pine aroma builds.
- Flower weeks 8-10: ripening and harvest. Judge by the trichomes, not the day count.
Choosing Your Setup: Space, Light and Pots
Forbidden Fruit is easy to house indoors. At around 1.2 m it suits a standard tent with a short veg, and its compact structure takes well to SCROG and LST that open the dense canopy to light.
Light should be strong to support the potent, resinous flowers. A full-spectrum LED at 30-40 watts per square foot over a trained canopy gets the most from the plant, helping both yield and the trichome development behind the high THC. Keep airflow good around the dense buds.
For containers, use 3-5 gallon pots indoors, or larger fabric pots and open ground outdoors where it yields far more. As a photoperiod, it transplants fine, so you can pot up as it grows.
Germinating and Raising Seedlings
The paper towel method is the easy, reliable start. Soak the seeds for 12-24 hours, then set them between damp paper towels on a covered plate, kept dark and warm at 70-85°F (21-29°C). A taproot usually shows in two to three days.
When the root reaches about 1-2 cm, plant it root-down a knuckle deep in a light, airy mix and keep the surface moist until it breaks ground. New to germination? Our beginner growing guides walk through it step by step.
The Vegetative Stage and Training
Because Forbidden Fruit is a photoperiod plant, you can veg as long as you like and use the full training toolkit, which autoflowers cannot handle.
Top it early to build multiple colas, then use LST or a SCROG net to spread the branches into a flat, even canopy so light reaches more bud sites. On a compact, dense indica, opening the canopy helps light get into the lower buds and lifts both yield and potency. Keep nitrogen available through veg, and plan for a moderate stretch after you flip to 12/12.
Feeding and Watering Forbidden Fruit
Feed to the plant’s vigor. Forbidden Fruit is a healthy, resinous hybrid, so it takes a solid bloom schedule, but build it up gradually and read the leaves rather than chasing the bottle. Use a nitrogen-forward base through veg, then shift to a bloom formula higher in phosphorus and potassium once you flip to 12/12.
Water by root-zone moisture. Demand climbs through late veg and flower, so let the top layer dry between waterings to keep oxygen at the roots, and expect a big outdoor plant to drink heavily as the buds fill out.
Flowering and Knowing When to Harvest
After the flip, the plant stretches for two to three weeks, then settles into dense, resinous bud production. The cherry, lemon, and pine aroma builds through the middle weeks, so run a carbon filter indoors and keep air moving around the colas.
As the 8-10 week window closes, let the trichomes decide. Harvest when most are cloudy with a few amber for the fullest effect, which is strong on this high-THC strain. After the cut, hang the branches in the dark at about 60°F (15-16°C) and 55-60% humidity for 7-14 days, then cure in jars, burping daily for the first weeks to protect that fruity flavor. ç
Growing Indoors vs Outdoors
Indoors, the compact size and training-friendly structure make Forbidden Fruit easy to run. Keep a flat canopy under strong light and a short veg, and the 450 g/m² indoor yield is reachable, with trichome-heavy, potent buds.
Outdoors is where it really produces, reaching a big 700-900 g per plant in a sunny spot with space and good soil. Plant after the last frost, give it full sun and a large root run, and support the branches as the dense buds get heavy.
How Tall and How Much? Height and Yield
Height is easy to manage. At around 1.2 m, Forbidden Fruit is compact and suits indoor tents well, and topping and training keep the canopy flat. Outdoors it has room to grow larger.
On yield, it is a medium indoor producer at 450 g/m² and a big outdoor one at 700-900 g per plant. Strong light, canopy management, and healthy roots are what move you toward the top of its range, and the outdoor plants carry by far the most.
Best US Climates for Forbidden Fruit
Forbidden Fruit does best in warm, sunny climates with a long season for its big outdoor yields. Growers in California and the West get the sun and space it needs to reach 700-900 g per plant.
Its 8-10 week flowering can also finish in temperate and northern states before the fall weather turns. In the humid Southeast, keep airflow up around the dense, resinous buds late in flower. For another cherry-flavored strain, see our Cherry Dream grow guide.
Common Problems When Growing Forbidden Fruit
A few predictable issues are easy to avoid.
Flipping to 12/12 too late
Forbidden Fruit stretches in early flower. If you flip when it is already near your light, the stretch pushes the colas into the lamp. Flip at about two thirds of your target height.
Humidity in dense, resinous buds
The high-THC buds are dense and sticky, which traps moisture. Keep late-flower humidity down and air moving around the canopy to protect the harvest.
Not supporting big outdoor plants
Outdoors it can carry 700-900 g on heavy, dense colas. Add stakes or a trellis before the buds get heavy to stop branches snapping.
Harvesting too early
On a strong, flavorful strain it is tempting to cut once the buds look ready. The 8-10 week window and cloudy trichomes are the real signal, so wait for them to get the full potency and flavor.
Making the Most of Your Harvest
Do not waste the trim. The resin-heavy sugar leaves make excellent bubble hash, dry sift, or infused oil that keeps the cherry-citrus flavor. The stems, roots, and fan leaves compost well and feed your next grow.
Is Forbidden Fruit Right for You?
If you want a high-THC indica with an exquisite cherry-citrus flavor, compact indoors and huge outdoors, yes. It is potent enough for connoisseurs yet easy enough for most growers, and the outdoor yield is excellent. Just respect the strength and support the big plants. For another cherry-flavored strain, see our Cherry Dream grow guide.
Frequently Asked Questions
Is Forbidden Fruit indica or sativa?
Forbidden Fruit is indica dominant, listed at 70% indica and 30% sativa, from Cherry Pie and Tangie. It grows as a compact, sturdy, resinous plant, and the effect leans relaxing and body-focused with a euphoric, happy lift from the Tangie side. It is a late-day and evening strain with some brightness.
Does Forbidden Fruit need a 12/12 light cycle?
Yes. Forbidden Fruit is a photoperiod strain, so indoors it needs the light switched to 12/12 to start flowering. You veg it under a longer schedule like 18/6, then flip to 12 hours on and 12 off. Outdoors it flowers naturally as late-summer days shorten.
How long does Forbidden Fruit take to flower?
Forbidden Fruit flowers in about 8 to 10 weeks once you switch to 12/12. That is the bloom stage only. Total time from seed also includes your veg period, usually a few weeks, so plan the overall grow around flowering plus however long you choose to veg.
How strong is Forbidden Fruit?
Forbidden Fruit is high in potency at 23 to 26% THC, so it suits experienced users and should be approached carefully by beginners. The effect is euphoric and happy before easing into relaxation, strong but balanced, with its rich cherry and citrus flavor adding to the experience.
How much does Forbidden Fruit yield?
Forbidden Fruit yields around 450 g/m2 indoors under strong light and a trained canopy, and a big 700 to 900 g per plant outdoors with space and sun. Light intensity, canopy management, and healthy roots move you toward the top of the range, and the outdoor plants carry by far the most.
How tall does Forbidden Fruit grow?
Forbidden Fruit is compact at around 1.2 m, which makes it easy to fit in an indoor tent, especially with a short veg. You can keep it tighter by topping and flipping to 12/12 earlier, or give it more veg and open ground outdoors to grow a much larger, higher-yielding plant.
Can you clone Forbidden Fruit?
Yes. As a photoperiod strain, Forbidden Fruit clones well, unlike autoflowers. Take cuttings from a healthy plant during veg, root them, and keep them under long light until you are ready to flower. Cloning lets you keep a favorite high-THC, fruity phenotype and skip germination on your next run.
