About Green Crack

Green Crack is a sativa-dominant cultivar prized for its sharp cerebral lift, bright citrus flavour and dependable flowering window. It suits growers in Nottingham who use protected outdoor sites or indoor rooms to manage the region’s cool northern summers; with attention to light, airflow and training it rewards with solid yields and dense, aromatic buds.

Grow Difficulty:

Growing Green Crack sits at a moderate difficulty level for those who manage ventilation and feeding well. In cool northern summers extra care with humidity and light intensity helps avoid stress and slow growth.

Flowering Time:

Flowering tends to be relatively fast for a sativa-leaning plant, generally finishing in 7–9 weeks. This makes it attractive for growers seeking quicker turnarounds.

Yield:

Yield indoors can be generous when plants receive good light and nutrients, often 450–550 g/m² under ideal conditions. Outdoors, a healthy plant can produce up to around 600 g in a favourable season.

Height:

Plants develop a dominant central cola with multiple side branches and can reach medium to tall heights. Expect a typical range of 80–160 cm depending on training and container size.

Environment:

Indoors Green Crack responds well to training and controlled environments for predictable results. In Nottingham outdoor plants can do well in sheltered spots but need protection from damp and late-season wind.

Climate:

In Nottingham this strain can be managed despite cool northern summers by favouring protected sites or indoor grows. Give plants ample light and warmth during flowering to offset the regional cool and shorten ripening time.

Q
I'm growing two Green Crack plants in a 1.2 x 1.2 m tent, any tips?
A
Verified answer
Use LST and a small SCROG to spread the canopy and aim for even light distribution; keep the canopy around 60–80 cm for efficient PAR use.

Q
My plants are stretching a lot, how can I control height?
A
Verified answer
Introduce training before the stretch finishes, reduce night temperatures slightly and use a marginally lower light intensity during early flower.
Common question Posted by Urbanseedbank Answered
Q
Should I defoliate heavily?
A
Verified answer
Selective defoliation is best; remove large fan leaves that block light to bud sites but avoid stripping too much during early flower.
