About Blue Guava
Blue Guava brings a fruity, tropical profile with a steady, relaxing high and moderate to high THC. The genetics pair Blueberry sweetness with Guava’s tropical zing, producing medium, bushy plants that suit indoor control or sheltered outdoor spots. In cooler UK summers it benefits from careful humidity management and good airflow to avoid mould. Medicinally it helps with sleep onset, pain relief and stress reduction while remaining reasonably clear-headed for daytime use.
Blue Guava is an indica-dominant hybrid with soothing, body-led effects. It pairs calming physical relief with a gentle uplift to the mind.
THC content is typically in the high-teens to low-twenties, offering a reliably potent experience. The potency suits regular users seeking lasting effects.
CBD is minimal and under 1% in most phenotypes. That low CBD level means therapeutic effects come mainly from the THC and terpenes.
Blueberry x Guava. The cross combines fruity, dessert-like terpenes from Blueberry with the tropical, sweet character of Guava.
Seeds are commonly sold as Feminised photoperiod varieties to ensure reliable female plants. Photoperiod control allows growers to extend the vegetative phase when more bushiness is desired.
Blue Guava can be intermediate in difficulty and performs best with careful management during cool northern summers. It benefits from consistent humidity control and good ventilation to prevent mould.
Flowering generally completes in 8 to 9 weeks for most phenotypes. A few plants may need up to 10 weeks to reach full resin development.
When given stable indoor conditions yields are moderate to high. Outdoor results may be reduced where seasons are short or persistently damp.
Plants typically remain medium in height with a compact, bushy structure. They respond well to topping and training to create a uniform canopy.
Indoors, Blue Guava thrives under controlled lighting and steady airflow, and can perform very well in Durham. Outdoors it prefers sheltered, sunny sites and will finish best in protected corners of gardens around Durham.
In Durham, with cool northern summers, choose a sunny, sheltered outdoor site or control conditions indoors. Protect buds from prolonged damp and consider a greenhouse or indoor environment to reduce mould risk.
The effect is calming and warming through the body while keeping a clear, engaged head. It eases tension and supports relaxed focus rather than heavy sedation.
Flavours are fruity and sweet with a distinct guava note and hints of blueberry and diesel. Smoke is smooth with a lingering tropical sweetness on the exhale.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Switch to a 12/12 light cycle to induce flowering and maintain that cycle for the full 8–10 week bloom period.
Keep relative humidity around 40–50% during flowering and lower it to the mid-30s in final weeks to reduce mould risk.
Start at around 50% of manufacturer strength and increase gradually; Blue Guava prefers steady feeding without sudden spikes.
Good indoor cannabis grow room setups prioritise airflow, dehumidification and slight negative pressure to keep bud zones dry and reduce condensation.
Harvest when trichomes are mostly cloudy with some ambers for balanced effects; clear trichomes indicate more time is needed.
Low-stress training, topping and SCROG work well to broaden the canopy and increase usable bud sites.
Dry until stems snap then cure in jars for at least 2–4 weeks; longer cures will refine aroma and smoothness.
Yes, in sheltered, sunny spots with good air movement; consider a greenhouse in cooler, damper regions to avoid late-season rot.
It suits beginners with basic experience, though intermediate skills in humidity control and pest management improve outcomes.
CO2 can boost yields under very high light and controlled conditions, but for most home grows good ventilation and light management are more cost-effective.
