STRNG Seeds – THCA Apple Jack Auto

THCA Apple Jack Auto delivers the crisp fruit-forward character of its parent strain in a fast, compact format. It combines sweet apple aroma with a creamy finish, all wrapped into a plant that’s easy to grow and quick to harvest.

The aroma blends sour green apple with subtle floral notes and a warm herbal undertone. As it matures, you may notice hints of pastry-like sweetness and mild spice coming through.

Expect a tart apple inhale with a soft, creamy exhale. The flavor is vibrant and smooth, with lingering notes of citrus zest, sweet herbs, and a touch of earthiness.

This autoflower remains on the shorter side, typically reaching 60 to 100 cm. Its compact height and structured side branching make it ideal for discreet indoor grows or limited vertical setups.

The full cycle is usually completed in about 9 to 10 weeks. It begins flowering automatically around week 3 and finishes quickly without the need to adjust light cycles.

Indoors under strong lighting, expect around 400–500g/m². Outdoor plants can yield between 50–100g each, depending on sunlight, pot size, and climate.

Yes, it’s perfect for urban or stealthy grows thanks to its short stature, manageable aroma, and fast cycle. Just be sure to give it plenty of light and protection from heavy rain.

Late-flower techniques like lowering nighttime temps and providing gentle UVB exposure can help. Keeping feeding light in the final weeks and curing slowly will also improve terpene retention.

Yes, its compact size and uniform growth make it great for SOG systems. Planting multiple autos in smaller pots can maximize space and yield under shared light.

While many fruit strains lean heavily into sweetness, this one balances tartness with creaminess, giving it more complexity. The apple-citrus flavor is clean and never overwhelming.

Autoflowering strains begin flowering based on age, not light cycle. THCA Apple Jack Auto will bloom automatically after about 3–4 weeks, regardless of how many light hours it receives.

Most growers run it on an 18/6 schedule (18 hours of light, 6 hours of darkness) throughout the entire cycle. Some use 20/4 to push faster growth if heat and power costs are manageable.

Yes, LST works well during the first two to three weeks. Gently bending and tying down branches early can help create a more open canopy and improve yield.

Topping can be done, but only if performed very early—before day 18 or so. Because autos grow on a fixed timeline, recovery time is limited. Many growers stick to LST to avoid stress.

For best results, sow the seed directly into its final container. Autoflowers don’t handle transplant shock well, and early root disruption can reduce yield.

Yes, it thrives outdoors in warm, sunny climates. Its short lifecycle helps it finish before autumn rains, and it’s small enough to tuck into discreet corners of gardens or patios.

Use light, well-draining soil rich in organic matter. Autoflowers do best in soils that aren’t too dense and allow for rapid root development, like mixes with added perlite or coco coir.

Start with mild veg nutrients during the first two weeks, then gradually shift to bloom nutrients high in phosphorus and potassium. Autos are sensitive to overfeeding, so less is often more.

Definitely. It responds well to organic inputs like worm castings, compost teas, and slow-release dry amendments. Many growers find that organics bring out richer flavor in the final product.

Keep temps between 21–27°C and humidity around 55% in veg, dropping to 40–45% in flower. Avoid high humidity late in bloom to prevent mold in the dense buds.
