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.

Grow Difficulty:

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 Time:

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.

Yield:

When given stable indoor conditions yields are moderate to high. Outdoor results may be reduced where seasons are short or persistently damp.

Height:

Plants typically remain medium in height with a compact, bushy structure. They respond well to topping and training to create a uniform canopy.

Environment:

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.

Climate:

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.

Common question Posted by Urbanseedbank Answered
Q
My buds seem fluffy mid-flower, what should I do?
A
Verified answer
Increase light intensity slightly and use gentle pruning to open the canopy; fluffy flowers often mean they need more direct light to fatten up.
Common question Posted by Urbanseedbank Answered
Q
I see early signs of bud rot, can I save the crop?
A
Verified answer
Remove affected areas immediately and improve airflow and dehumidification; severely infected buds should be discarded to protect the rest.
Common question Posted by Urbanseedbank Answered
Q
Should I top during veg or keep a single tip?
A
Verified answer
Top once early in veg to encourage branching, then use LST to spread the canopy for even light distribution.

Q
What's a good flushing routine before harvest?
A
Verified answer
Flush with plain water for 7–10 days if using synthetic nutrients; for organic grows a shorter flush is often sufficient.
