STRNG Seeds – THCA Pineapple OG Auto

THCA Pineapple OG Auto brings together tropical sweetness and earthy OG depth in a fast, compact autoflower format. It captures the flavor complexity of the original while offering the convenience of a rapid grow cycle.

As it flowers, this strain releases a bold tropical scent—pineapple, citrus, and mango up front—backed by dank OG funk and subtle herbal spice. The aroma is punchy and fills the space quickly.

Aim for temperatures between 21–27°C. Keep humidity around 55% in veg and reduce to 40–45% in flower. Proper airflow helps protect against mold in the dense buds.

This autoflower stays relatively compact, usually topping out between 70 and 100 cm. It’s suitable for small tents, balconies, or stealth setups, while still producing sizable colas.

THCA Pineapple OG Auto completes its full lifecycle in 9 to 10 weeks. It begins flowering automatically after the third week, making it a quick and efficient cultivar to grow.

Indoors, it can produce around 400–500g/m² under high-intensity lights. Outdoor plants typically yield 50–100g each, depending on sunlight exposure and container size.

Yes, it’s easy to grow and doesn’t require complex techniques. As long as you avoid overwatering and overfeeding, it performs reliably and responds well to basic care.

Buds are dense, resinous, and round—often coated in a thick layer of trichomes. Expect lime green coloration with amber hairs and occasional hints of purple in cooler environments.

Harvest when trichomes are mostly cloudy with some amber, and when the pistils have darkened and curled inward. This usually occurs around weeks 9–10.

Absolutely. Its compact height and bushy structure make it perfect for tight indoor grows, closets, or balconies. It thrives in confined environments with proper airflow and lighting.

Autoflowering means the plant transitions from veg to flower automatically based on age, not light schedule. There’s no need to switch to a 12/12 light cycle—it will flower on its own.

An 18/6 light schedule (18 hours of light, 6 hours of darkness) from seed to harvest works well. Some growers use 20/4 to accelerate development if temperatures and energy costs allow.

Light low-stress training (LST) can improve airflow and light penetration. It’s best to start early, before the flowering stretch begins, as autos don’t like heavy stress or late pruning.

Topping is possible but risky due to the short veg cycle. If you choose to top, do it early—by day 15 to 18 at the latest. Most growers stick with LST for safety.

Autoflowers prefer being started in their final container to avoid transplant shock. A 3–5 gallon fabric pot works well for supporting root development and drainage.

Yes, it grows well outdoors in sunny, warm climates. Its short cycle lets it finish before seasonal weather changes, and its compact size keeps it discreet and manageable.

Use light, well-draining soil enriched with organic matter. Avoid compact or heavy soils—adding perlite or coco coir can improve aeration and root health.

Water when the top 1–2 cm of soil is dry. It’s better to slightly underwater than to risk soggy roots. Consistent hydration with good drainage is key, especially during early flower.

Start with a balanced veg nutrient, then switch to a bloom formula with more phosphorus and potassium once flowering begins. Go easy on feeding—autos are sensitive to nutrient excess.

Yes, it does very well in organic systems. Many growers use compost teas, worm castings, and slow-release amendments to bring out its full terpene potential.
