Royal King Genetics β€” first-party test batch

Numbers below are from our internal seed-lot QC and verified grower submissions, not breeder marketing. Determined from a single batch tested 2026-04-12 on 475 seeds.

Germination rate: 99.0% (n=475)
Last QC test date: 2026-04-12
Indoor yield: 368-538 g/mΒ² (avg across 12 verified grower reports)
Outdoor yield: 658-890 g/plant (avg across 7 verified grower reports)

About American Haze Feminized

American Haze is a 16/84 sativa testing at 24% THC with a pinene-dominant terpene profile. At a practical level, this means a plant that stretches 40-60% after the flip and produces elongated colas with good light penetration through the canopy, finishing in 9-11 weeks. The Pinene/Limonene combination shapes both the aromatic profile and the effect character β€” this is not a one-dimensional strain.

Growing Parameters

Flowering time: 9-11 weeks from flip. Indoor yield at 600+ PPFD: 450-550g/mΒ². Outdoor in full sun with 5+ gallon containers: 400-600g/plant. Plant height indoors after training: Short-Medium (2-3.5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Pinene production peaks when day/night temperature differential exceeds 10Β°F in the final two weeks β€” growers who drop nighttime temps to 62-65Β°F during this window report stronger aromatic development.

This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.

Effects and Use

At 24% THC, American Haze delivers creative, energetic effects with a pinene-influenced character. The onset is cerebral β€” a brightening of the mental space that arrives within minutes and can enhance focus, creativity, and conversation for 2-3 hours before gradually softening. The body stays comfortable without heaviness. The pinene dominance adds a clarity that many users describe as "functional".

Terpene Profile

Dominant terpenes: Pinene (primary), Limonene (secondary), Caryophyllene (tertiary). This combination produces a flavor that rewards patience in the cure β€” the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.

Who Should Grow American Haze

Best suited for growers who want control over their plant size and harvest timing β€” photoperiod genetics let you veg as long as you want before triggering flower. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results. Ships discreetly to all 50 US states with our germination guarantee.
