STRNG Seeds – THCA Apple Jack

THCA Apple Jack stands out with its crisp, tart apple profile blended with sweet cream and spice. It balances both freshness and depth in its terpene expression, making it especially memorable for flavor-forward cultivators.

During flowering, this strain releases a sweet, tangy apple scent with underlying notes of warm spice, reminiscent of apple pie with a floral finish. The aroma intensifies as the buds mature.

Expect a clean and fruity inhale with sharp green apple up front, followed by creamy vanilla and a soft herbal spice on the exhale. The flavor is balanced and lingers on the palate without being overpowering.

THCA Apple Jack is a balanced hybrid that leans slightly toward the sativa side in terms of its growth pattern and overall energy. Its effects tend to start with uplift before gradually mellowing.

It performs very well in SCROG thanks to its uniform branching and balanced stretch. It fills out screens quickly and produces dense colas across the canopy.

Buds are tight and have a good calyx-to-leaf ratio, making trimming straightforward. A pre-harvest defoliation can make post-harvest processing even easier.

Buds are medium to large, densely packed, and covered in frosty trichomes. Expect light green coloring with hints of amber and orange pistils, giving them a warm, inviting appearance.

It tends to grow to medium height—about 100 to 140 cm indoors. Outdoors, it may stretch a bit taller, especially in warm climates with extended veg periods.

Flowering time is typically 9 to 10 weeks indoors. Outdoor growers can expect to harvest around early to mid-October, depending on the local climate.

Indoors, yields average around 450–550g/m² under strong lighting. Outdoor plants can produce more, especially with ample root space and ideal conditions.

Feminized seeds are bred to produce only female plants, which are responsible for growing the resin-rich buds. This eliminates the need to sex plants and increases the efficiency of your grow.

While it prefers warmth, it can still perform in cooler regions if planted early enough. In colder zones, consider using greenhouses or raised beds for temperature control.

With proper attention to feeding, light, and training, THCA Apple Jack is manageable for newer growers. It’s forgiving and adaptable but responds best to dialed-in conditions.

Yes, like all feminized photoperiod strains, it requires a change to a 12/12 light cycle to begin and maintain the flowering stage. Outdoors, flowering is triggered naturally by shorter days.

Look for cloudy trichomes with a touch of amber and darkened pistils that have curled in. A magnifier or jeweler’s loupe is helpful for precise timing.

It performs very well indoors due to its manageable size and structure. Outdoors, it thrives in warm, moderately dry climates with good airflow and sun exposure.

THCA Apple Jack responds well to topping, LST, and SCROG methods. These techniques help open the canopy, increase bud sites, and maintain an even structure.

During veg, provide 18–20 hours of strong light daily. Once flowering begins, maintain a strict 12/12 cycle. LED or HPS lighting both work well with this strain.

Ideal conditions include temperatures between 22–27°C and humidity around 50% in veg and 40–45% during flower. Adequate airflow helps prevent mold on its dense buds.

Water when the top inch of soil feels dry. It prefers a rhythm of wet and dry cycles to support root development and avoid nutrient lockout. Avoid overwatering in flower.
