Guava Cannabis Seeds by Garden of Green
Guava is a feminised cannabis seed from Garden of Green that delivers an uplifting, energising effect backed by 21% THC and properly tropical fruit flavours. A direct descendant of OG Kush, this strain inherited the kind of terpene profile that makes you stop and sniff the jar twice. It flowers in 8–9 weeks, stays at a manageable height, and rewards growers with solid yields whether you're running a tent or planting outdoors. If you want a daytime strain that actually tastes as good as it smells, Guava is the one we'd point you towards.
Pack Sizes
Guava seeds come in two pack sizes: 3 seeds or 5 seeds. If you're running a single tent and want to pick the best phenotype, go with 5 — it gives you room to select the strongest plant without putting all your eggs in one basket. The 3-pack works fine if you've got limited space or just want a straightforward grow without extras.
Why Guava Seeds Deserve a Spot in Your Grow Room
We've seen plenty of "fruity" strains that smell like chemicals and taste like disappointment. Guava isn't one of them. Garden of Green crossed their original Guava genetics with OG Kush, and the result is a plant that genuinely delivers on the tropical fruit promise. The terpene profile hits you the moment you crack a cured bud — think ripe guava, mango undertones, and a sweetness that lingers on your tongue after exhaling. If you vape it, those flavours sharpen up even more.
At 21% THC, this isn't a mild afternoon smoke. It comes on with a cerebral lift that gets your head moving — creative thoughts, motivation, the kind of energy that makes you want to actually do things rather than sink into the sofa. That makes it a proper daytime strain, which is harder to find than you'd think. A lot of strains marketed as "energising" still leave you foggy after an hour. Guava keeps the clarity going.
The honest limitation? If you're a casual or infrequent user, 21% THC can catch you off guard. According to dosage guidance from experienced growers, new users should start with a smaller amount and see how the cerebral effects settle before going back for more. This isn't a criticism — it's just respect for the plant's potency.
Growing Guava Seeds: What to Expect
Guava seeds develop into moderately tall plants that stay between 130cm and 160cm depending on how much vertical space you give them. In a standard indoor tent, you can keep them on the shorter end with some light training. Outdoors, they'll stretch towards that 160cm mark, which is still manageable compared to some sativa-dominant monsters that try to outgrow your fence.
Flowering takes 8–9 weeks indoors. Outdoors, plan your harvest for mid-October. That's a fairly standard timeline — nothing that'll test your patience beyond reason. The yields are where Guava quietly impresses: up to 450g/m² indoors and up to 550g/plant outdoors. Those are solid numbers for a strain that doesn't demand expert-level growing skills.
One thing we'd flag: if you're working with a smaller tent, 10–15 litre pots are plenty. You don't need massive containers to get good results from this strain. Give it decent light, keep your environment stable, and Guava does the rest without drama. It's the kind of plant that rewards consistency over complexity.

Guava Terpene Profile and Flavour
The terpene profile is where Guava really earns its name. The dominant aromas are tropical fruit — ripe guava, obviously, but also layers of sweet citrus and a subtle earthiness from the OG Kush side. When you grind the dried flower, the room fills up fast. It's not a strain you can discreetly prepare if anyone's nearby.
Flavour-wise, smoking delivers the tropical sweetness with a smooth exhale and a pleasant aftertaste that doesn't turn acrid. Vaping at lower temperatures (around 180–190°C) pulls out even more of those fruit terpenes — you get a cleaner, sharper guava flavour that's genuinely enjoyable. If you've got a dry herb vaporiser, this is a strain worth running through it.
Guava also works well in edibles if you're the kitchen-experiment type. The fruity terpenes add a natural sweetness that complements baked goods and gummies without that overwhelming "weed taste" some strains bring. Decarb your flower properly first — 110°C for 40 minutes in the oven — and you've got a versatile ingredient.
| Consumption Method | Flavour Notes | Best For |
|---|---|---|
| Smoking (joint/pipe) | Sweet tropical fruit, earthy undertone | Quick sessions, social settings |
| Vaping (180–190°C) | Sharp guava, clean citrus | Flavour chasers, terpene appreciation |
| Edibles | Subtle fruity sweetness | Longer-lasting effects, kitchen experiments |
Guava Effects: Daytime Energy and Creativity
Guava's effects lean heavily towards cerebral stimulation and physical energy. The onset is relatively quick — within minutes you'll notice a sharpening of focus and a wave of motivation that makes it a strong choice for creative work, outdoor activities, or just powering through a to-do list. It's not a couch-lock strain by any stretch.
That said, 21% THC means the effects are properly potent. According to guidance from experienced cultivators, if you're not a regular user, starting with a single puff and waiting 10–15 minutes before deciding on more is the sensible approach. The cerebral intensity can be overwhelming if you overdo it — dry mouth and mild anxiety have been reported at higher doses.
Compared to something like OG Kush itself, which tends towards heavier body relaxation, Guava keeps things lighter and more functional. If you've grown or smoked OG Kush and wished it had more daytime energy, Guava is essentially that wish granted with a tropical fruit wrapper.
Complete your Guava grow setup with a propagation kit and root stimulator to give your seedlings the strongest possible start. Pair with a carbon filter if you're growing indoors — the terpene production on this strain is no joke, and your neighbours will notice without one.
How to Grow Guava Cannabis Seeds
- Germinate your Guava seeds using the paper towel method: place seeds between two damp paper towels on a plate, cover with a second plate, and keep in a warm spot (20–25°C). Taproots typically appear within 24–72 hours.
- Transfer germinated seeds taproot-down into small pots (0.5–1 litre) filled with light, airy seedling soil. Keep the soil moist but not waterlogged.
- Once seedlings develop 3–4 sets of true leaves, transplant into their final containers. For indoor grows, 10–15 litre pots work well. Outdoors, plant directly into prepared soil or use 20+ litre pots for maximum root space.
- Maintain 18 hours of light during vegetative growth. Guava responds well to low-stress training (LST) to keep the canopy even and maximise light penetration to lower bud sites.
- Switch to a 12/12 light cycle to trigger flowering. Expect 8–9 weeks before harvest. Outdoor growers should watch for trichome development from late September, with harvest around mid-October.
- Harvest when trichomes are mostly milky with a few turning amber. Dry in a dark, well-ventilated space at 18–22°C for 7–10 days, then cure in glass jars for at least 2 weeks. Longer curing brings out more of those tropical terpenes.
Frequently Asked Questions
Is Guava an indica or sativa strain?
Guava leans towards sativa-dominant effects — uplifting, cerebral, and energising — though its OG Kush parentage gives it some indica structure in the plant itself. Growth-wise, it stays moderately compact at 130–160cm.
What does Guava cannabis taste like?
Tropical fruit is the dominant flavour — ripe guava with citrus undertones and a subtle earthy finish from the OG Kush genetics. Vaping at lower temperatures makes the fruit notes even more pronounced.
How long does Guava take to flower?
Guava completes its flowering phase in 8–9 weeks indoors. Outdoor growers can expect to harvest around mid-October. That's a standard timeline — nothing unusually long or short.
What yields can I expect from Guava seeds?
Indoor grows produce up to 450g/m², while outdoor plants can reach up to 550g/plant. These are solid yields that don't require advanced techniques — consistent environment and decent light do most of the work.
Is Guava too strong for beginners?
At 21% THC, Guava is potent. If you're an infrequent user, start with a small amount and wait before taking more. The cerebral effects come on quickly and can be intense if you overshoot. Experienced users will find it stimulating without being overwhelming.
Can I grow Guava seeds indoors and outdoors?
Yes, Guava thrives in both environments. Indoors, it stays around 130cm and fits comfortably in standard tents. Outdoors, it can stretch to 160cm and benefits from direct sunlight and natural airflow.
What is the best way to consume Guava cannabis?
Vaping between 180–190°C gives you the cleanest flavour. Smoking works well for quick sessions. Guava's fruity terpenes also make it a strong candidate for edibles — the natural sweetness complements baked goods without an overpowering cannabis taste.
