STRNG Seeds – THCA Girl Scout Cookie Auto

THCA Girl Scout Cookie Auto delivers the same dessert-like flavor and gorgeous bud structure but with the speed and convenience of autoflowering genetics. It flowers automatically and completes faster, making it ideal for growers who want quicker harvests.

Expect a sweet, bakery-style aroma with hints of vanilla, nutmeg, and light mint. The scent intensifies during flowering, filling grow spaces with warm, doughy notes and subtle spice.

Look for cloudy trichomes with some amber appearing and darkened pistils curling inward. Using a jeweler’s loupe helps you dial in harvest time precisely.

This autoflower stays compact and manageable, typically reaching 60–100 cm. It’s ideal for small grow spaces, stealth setups, or those with limited vertical room.

THCA Girl Scout Cookie Auto finishes in about 9 to 10 weeks from germination. It’s a great choice for fast, reliable harvests throughout the year.

Indoor growers can expect 400–500g/m² under strong lighting. Outdoor plants in optimal conditions may yield 50–100g per plant depending on light and pot size.

Buds are dense, frosty, and feature a classic cookie appearance—chunky nugs with deep green hues, purple streaks, and vibrant orange hairs.

Water when the top inch of soil feels dry. Overwatering is a common mistake with autos, so allow some dry-back between waterings.

Yes, the strain produces thick trichome coverage that translates well to solventless extractions like dry sift and rosin. The flavor holds up nicely in concentrates.

It’s a great pick for growers who value strong aroma, rich flavor, and fast turnaround without sacrificing quality. Beginners and experienced growers alike enjoy its simplicity and results.

Autoflowering plants begin flowering automatically after a few weeks of growth, regardless of light cycle. This makes them easier to manage and allows for harvests year-round indoors.

Many growers use 18 hours of light and 6 of darkness throughout the entire cycle. Others opt for 20/4 to push growth a little further if temperatures are well-managed.

Light low-stress training (LST) works well and helps open the canopy. If you want to top, it must be done very early—before day 21—to avoid stunting.

To avoid stress, it’s best to start it in its final pot. Autoflowers don’t respond well to transplanting once roots are established. Use a 3–5 gallon pot for best results.

Absolutely. It’s well-suited to outdoor environments with plenty of sun. Because of its short cycle, it can be harvested before weather becomes a concern in many regions.

Use a balanced feeding schedule. Start with light veg nutrients, then transition to bloom boosters rich in phosphorus and potassium. Avoid overfeeding—autos are sensitive to strong doses.

Yes, it performs well in living soils and with organic nutrients. Compost teas and dry amendments will support its flavor profile and resin production.

Aim for temperatures between 21–27°C with humidity around 55% in veg and 40–45% during flowering. Proper airflow helps avoid mold, especially near harvest.

Yes, it’s known for impressive trichome production. Buds often glisten with resin late in flower, making them sticky and aromatic—great for visual appeal and concentrate yield.

Definitely. Its small stature, fast growth, and discreet aroma in early veg make it a great choice for grow tents, closets, or balconies with some odor control.
