About Apple Jack

Apple Jack is a sativa-dominant hybrid bred from Jack Herer x Northern Lights that delivers a clear, energising high and a distinct apple-citrus aroma. It suits growers in mild southern growing climate areas who can manage humidity and provide good airflow, and it responds well to training for improved yields.

Grow Difficulty:

Growing Apple Jack is moderately challenging for new growers and rewards attention to feeding and structure. In mild southern growing climate it tolerates some variability but benefits from consistent humidity control and airflow.

Flowering Time:

Flowering generally completes in 8 to 9 weeks indoors. Outdoor plants are ready by late September to early October in similar climates.

Yield:

Indoor yields are generally medium to high with good training and light, averaging around 450 to 550 g/m². Outdoor plants can produce 300 to 500 g per plant under ideal conditions.

Height:

Plants develop a medium-tall structure with long internodes and airy buds. Expect 1.5 to 2.5 m heights outdoors without topping.

Environment:

Apple Jack adapts well to indoor systems where SCROG or SOG training maximises light use. Outdoor plants perform well in London gardens and on sheltered balconies, provided the season is dry at harvest.

Climate:

Growing Apple Jack in London benefits from the city's mild southern growing climate, which extends the outdoor season and reduces frost risk. Keep an eye on late-season rain and manage humidity to prevent mould in the airy buds.

Common question Posted by Urbanseedbank Answered
Q
My plants look droopy after watering, is that overwatering?
A
Verified answer
Droop after watering is common; check pot weight and allow the topsoil to dry slightly before the next feed to avoid root oxygen stress.
Common question Posted by Urbanseedbank Answered
Q
How often should I defoliate Apple Jack?
A
Verified answer
Remove large fan leaves that block light to bud sites, but avoid heavy defoliation late in flower; do it sparingly and only where airflow will improve.
Common question Posted by Urbanseedbank Answered
Q
What humidity should I aim for in flower?
A
Verified answer
Keep relative humidity around 40-50% during mid to late flower to reduce mould risk while preserving trichome development.
Common question Posted by Urbanseedbank Answered
Q
Is flushing necessary before harvest?
A
Verified answer
Many growers perform a short flush of plain water in the final 7-10 days to clean out excess fertiliser, though opinions vary.
Common question Posted by Urbanseedbank Answered
Q
How do I know when to harvest?
A
Verified answer
Monitor trichomes for a mix of cloudy and a few amber heads for balanced effects and check pistils; timing depends on desired effect profile.
