Ultra G13 Strain Overview

Ultra G13 is a autoflowering evenly balanced hybrid (50% indica/50% sativa) strain with a character all of its own. This well-regarded bud boasts a THC level that ranges from 21-27% on average, with 1% CBD. Seeds come in autoflower form, and demand from home growers has never really slowed.

The Ultra G13 high balances both sides of its lineage: a happy head buzz up front, and a soothing physical warmth that follows a few minutes behind. The handoff between head and body is seamless, making it easy to dose for either a productive afternoon or a slow evening. Because of these effects, Ultra G13 is often chosen for managing chronic stress, muscle tension and mild to moderate depression, especially by those who want relief without reaching for anything heavier.

Ultra G13 has a delicious berry and chocolate flavor that lingers on the tongue long after the exhale, with an aroma to match that grows sharper as the buds are broken apart. Each exhale leaves a berry-tinged aftertaste that keeps you coming back for one more taste. This bud has dense grape-shaped forest green nugs with cool blue undertones, curly amber hairs and a fine dusting of milky white trichomes.

For growers, Ultra G13 offers an easy, forgiving grow that suits first-time cultivators — expect plants finishing in as little as 8-9 weeks from germination, at home indoors or outdoors. It shrugs off common beginner mistakes, and yields stay respectable even when conditions are less than perfect. Plants stretch to a medium height with strong side branching, equally at home in a tent or a garden bed. Its genetics run through the wider Ultra family — see Gorilla Snow Ultra CBD and Grape Ultra for close relatives worth comparing before you buy.
