Double Diamond Strain Overview
Double Diamond 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 18-24% on average, with 0.8% CBD. Seeds come in autoflower form, and demand from home growers has never really slowed.
The Double Diamond 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. These combined effects make Double Diamond a frequent pick among patients dealing with chronic stress, muscle tension and mild to moderate depression, and a reliable standby for anyone medicating on a schedule.
On the palate, expect coffee and diesel up front, backed by an aroma that fills the room the moment the jar opens. Each exhale leaves a coffee-tinged aftertaste that keeps you coming back for one more taste. This bud has compact rounded olive green nugs with deep purple undertones, rust-colored hairs and a fine dusting of milky white trichomes.
For growers, Double Diamond 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 Diamond family — see Strawberry Diamond and The Diamond Mill for close relatives worth comparing before you buy.
