What’s In The STRNG Seeds Grow Kit
Your grow kit will arrive at your address in a discreet package. Open the box to reveal the components within:
- 2 autoflowering seeds from STRNG Seeds of your choice
- 1 germination plug
- 2 high-quality coco compost mixes (over 3 liters of dirt when expanded)
- High-quality organic nutrients
- Biodegradable fabric container
- Instruction manual
The germination plug has predetermined pH levels, offering the best possible start to any grow. These biological devices self-regulate to maintain an exact air-to-water ratio, and the lack of borders (by layers of plastic or similar) air-prunes the roots, creating a healthy and vibrant network.
The coco compost arrives in a compact form and expands with the addition of water, making for light and discreet delivery. Finally, the organic nutrients supply all the macro and micronutrients required to raise a healthy plant.
How To Use The STRNG Seeds Premium Grow Kit
Follow the instructions below for the easiest growing experience of your life:
- Unpack the STRNG Seeds Premium Grow Kit.
- Empty the contents into a tray.
- Spray the coco plug with water and watch it expand.
- Apply water to the soil mix and place it into the container.
- Sow one seed into the plug and add the plug to the soil. ***PLEASE USE ONLY ONE SEED PER CONTAINER
- Place the container in a sunny spot with a consistent temperature of between 18–28°C.
- Follow the instructions and watch your plant thrive.

It offers the same deep purple color, fruity flavor, and resin-rich buds as the original — but in a shorter, faster, and more space-efficient autoflower format.
It’s rich and smooth, with dominant notes of grape, wild berries, and light earth — followed by a subtle herbal exhale, especially after a proper cure.
Only minimal. Remove large fan leaves that block light or airflow, but avoid aggressive pruning, as autos have little time to recover.
It stays compact — usually between 60–90 cm indoors — forming a bushy frame with short internodes and dense, colorful colas.
Full-spectrum LEDs with good canopy coverage work great. This strain responds well to even light distribution due to its short, wide frame.
Yes, although cooler nights can enhance the purple tones. Many phenotypes display purple hues naturally, even under steady warm conditions.
Only minimal. Remove large fan leaves that block light or airflow, but avoid aggressive pruning, as autos have little time to recover.
Yes, under the 2018 Farm Bill. Please read HERE.
It’s great for flavor-first growers, those with limited space, and anyone looking to harvest boutique-quality flower quickly with minimal training.
The scent starts floral and slightly tart, then matures into a strong berry-grape profile with hints of spice and sweetness as the buds ripen.
Of course! You can see our equipment collection HERE.
Most phenotypes finish in 9–10 weeks. With ideal lighting and care, some can be ready as early as day 65 from germination.
No. Like all autos, it begins flowering based on age, not light. Most growers use 18–20 hours of light per day from start to finish.
Not recommended. Instead, use gentle low-stress training to guide shape early in veg and support even canopy development.
Yes. It’s easy to grow, resilient, and delivers standout color and flavor with minimal intervention — a solid pick for beginners.
Absolutely. Its short life cycle makes it perfect for multiple runs per season in climates with long growing windows.
While purple hues often appear naturally, slightly cooler nighttime temperatures in the final two weeks can help deepen the coloration without compromising bud health.
A 3–5 gallon (11–19L) pot is ideal. Autos prefer being planted directly in their final container to avoid stress from transplanting.
Start bloom feeding around week 3 or once pre-flowers appear. Begin at half strength and adjust based on the plant’s structure and leaf color.
21–26°C with 55% RH in veg and 40–50% in flower. Stable airflow and humidity control help prevent moisture issues in its dense colas.
