- Three-way classic cross: Haze, Skunk, and Northern Lights genetics in a single feminized seed.

- Outdoor yield payoff: Up to 600g per plant for growers who give her the full season.
About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.

Shining Silver Haze: Full Haze Pedigree, Faster Than You'd Expect
Royal Queen Seeds built Shining Silver Haze from three pillars of cannabis history: Haze for the cerebral soar and sativa stretch, Skunk for resin density and punch, and Northern Lights for structure and a shorter flower window. The result is a sativa-dominant feminized strain that carries the full Haze character without the 14-week commitment that puts most growers off. THC sits at 21%, a range that puts this firmly in experienced-user territory without being unapproachable. These seeds deliver the prestige of Haze genetics in a format that actually fits a real grow schedule.
Breeders take note: Shining Silver Haze delivers this same Haze champion as regular seeds, males included. RQS's modern medal magnet is Royal Gorilla, carrying the Gorilla genetics that swept the 2014 Cup.
Compact Indoors, Commanding Outdoors
Indoor plants top out at 100cm, which is genuinely compact for a strain with this much sativa DNA. You can run her in a standard tent without aggressive training, though LST will help fill the canopy and push indoor yields toward 525g/m². The flowering time of 9-10 weeks is where the Northern Lights influence earns its place: fast for a Haze-lineage strain, it fits a straightforward photoperiod schedule rather than demanding a dedicated long-cycle room. Take her outside and the picture changes. She can reach up to 200cm under the sun, and outdoor plants can yield up to 600g per plant, a return that rewards any grower patient enough to let her run the full season. The contrast between the two environments is one of the more useful things to know about this strain before you commit.
A Cerebral Arc Worth the Grow
The effect profile is the reason experienced growers keep coming back to Haze-lineage strains. Shining Silver Haze opens with a wave of euphoria that sharpens quickly into something more cerebral and psychedelic in character, uplifting without being frantic. It's a daytime or early-evening experience: focused energy rather than sedation, the kind of effect that suits creative work or a long social session. There's no flavour data confirmed for this listing, so the sensory story here is the effect arc itself, and that arc is the strain's strongest argument. If you've grown milder sativa hybrids and wanted more, this is the logical next step.
