STRNG Seeds – G13

G13 is known for its dense buds, deep earthy aroma, and mysterious lineage often associated with underground breeding lore.

Yes — it performs exceptionally well indoors, with a controllable structure and consistent flowering behavior.

Expect pungent earthy tones layered with pine, musk, and subtle sweet notes that intensify during late flower.

Begin flushing 10–14 days before harvest to enhance aroma, taste, and flower smoothness.

Hand trimming is best due to their density and trichome coverage — machine trimmers may damage their structure.

It’s moderately easy — forgiving in veg, but rewards experienced growers who can dial in feeding during bloom.

Buds are chunky, dense, and heavily frosted — often showcasing dark green hues with burnt orange pistils.

G13’s exact lineage is unknown, but it’s widely believed to be an old-school indica-dominant hybrid with government lab origins.

G13 typically finishes in 8–9 weeks indoors, with some phenos ready slightly earlier depending on conditions.

Its unique legacy, rich terpene profile, and excellent indoor performance make it a standout for collectors and craft growers.

Yes — it responds positively to topping and LST early in veg, helping to boost lateral growth and yield.

Use topping, LST, and SCROG for even canopy development and improved light penetration across the plant.

Keep temperatures between 68–78°F (20–26°C) with low humidity in bloom to avoid mold on its dense buds.

It grows well in both — soil enhances terpene expression while hydro delivers faster growth and higher output.

Water when the top inch of medium is dry, increasing frequency as the plant matures and flowers develop.

It has decent resistance, but due to dense flowers, good airflow and humidity control are essential in late flower.
