About Grandi Guava

Grandi Guava is a sativa-dominant hybrid that pairs ripe guava flavour with a focused, sociable high. It flowers quickly for its type and performs well for intermediate growers who manage humidity and airflow.

Grow Difficulty:

Cultivation difficulty is intermediate and it rewards growers who maintain steady airflow and mildew prevention in a mild southern growing climate. Beginners will need to learn basic training and moisture control to avoid mould issues.

Flowering Time:

Indoor flowering finishes in eight to nine weeks under stable conditions. Outdoor plants typically harvest in late September in suitable regions.

Yield:

Yields are medium to high when plants receive good light and ventilation. Indoor growers can expect competitive grams per square metre while outdoor plants respond well to nutrient support.

Height:

The plant shows a medium to tall, open structure with a dominant central cola. Expect significant stretch early in flower and long lateral branches.

Environment:

Indoors, Grandi Guava responds well to SCROG and light training and Surrey growers often favour controlled tents and gentle defoliation. Outdoors in Surrey it performs reliably in gardens and greenhouses when autumns stay mild.

Climate:

Growing Grandi Guava in Surrey benefits from the region's mild southern growing climate and typically longer frost-free periods. You must still manage humidity and airflow carefully to prevent mould during humid spells.

Common question Posted by Urbanseedbank Answered
Q
What light schedule gives best results indoors?
A
Verified answer
Use 18/6 for veg and switch to 12/12 for flowering; some growers use an extended veg to build mass before flip.
Common question Posted by Urbanseedbank Answered
Q
How much should I top before switching to flower?
A
Verified answer
Top two to three times during veg to create a bushier canopy, finishing training a couple of weeks before the light flip.

Q
Any tips for outdoor nutrient strategy in Surrey?
A
Verified answer
Start with a balanced base, add bloom-focused feeds when buds form and supplement with potassium during peak flower while monitoring runoff.
Common question Posted by Urbanseedbank Answered
Q
My leaves are curling after feeding, is it burn?
A
Verified answer
Likely nutrient stress; check pH and EC, flush lightly if salts have built up and reduce feed strength.
