About Crystal

Crystal is a hybrid bred for balanced effects, strong terpene expression and reliable resin production. It suits growers who want a versatile plant that performs well under controlled indoor conditions and can handle cautious outdoor cultivation in temperate regions.

Grow Difficulty:

Under variable British weather this strain shows moderate resilience but benefits from attentive feeding and humidity management. Growers should be prepared to manage pests and mould proactively during damp spells.

Flowering Time:

Flowering typically finishes in 8 to 10 weeks under stable indoor conditions. Outdoor plants in a favourable season will usually be ready by late September to October.

Yield:

With good technique and adequate light the indoor yield is medium to high and consistent. Outdoor yields can surpass indoor results in a warm, sheltered site but are season-dependent.

Height:

Plants develop a compact to medium frame with sturdy branches suited to heavy buds. Indoor specimens usually sit between 80 and 140 cm while outdoors they may stretch taller.

Environment:

Crystal responds well to controlled indoor methods such as SCROG and topping for even canopy development. In Norfolk it can be successful outdoors if planted in a sheltered microclimate to reduce wind and rain exposure.

Climate:

Growing Crystal in Norfolk requires attention to sudden rain and cool autumns due to variable British weather. Choose a sheltered outdoor site or have containers ready to move indoors to avoid rot and wind damage.

Common question Posted by Urbanseedbank Answered
Q
My buds look a bit mouldy after rain, what now?
A
Verified answer
Remove affected buds, increase airflow, and consider harvesting early if rot is widespread; for future crops use sheltered spots or move plants indoors during wet spells.
Common question Posted by Urbanseedbank Answered
Q
Leaves are yellowing in late flower, normal?
A
Verified answer
Some yellowing is normal as plants redirect energy to buds, but check pH and nutrient levels to rule out deficiencies or lockout.
Common question Posted by Urbanseedbank Answered
Q
LEDs seem to burn tips despite being low heat, help?
A
Verified answer
Check light distance and PAR; excessive intensity or small canopies can cause tip burn even with LEDs, so raise lights or reduce intensity.
Common question Posted by Urbanseedbank Answered
Q
When's the best time to train Crystal indoors?
A
Verified answer
Main training should happen in early veg when branches are flexible; final low-stress training can continue into early flowering for canopy control.
Common question Posted by Urbanseedbank Answered
Q
How do I optimise trichome production?
A
Verified answer
Maintain stable late-flower conditions, avoid overfeeding, and consider a slight drop in night temperature to encourage resin without stressing the plant.
