Super Silver Haze Seeds

Super Silver Haze consistently tests between 18-23% THC across verified grows. The lower end of that range (18-19%) is typical when plants are harvested slightly early or grown under suboptimal light intensity; dialing in the full 8-10 week flowering period under strong lighting pushes results toward the 22-23% ceiling. This range places Super Silver Haze above mid-tier sativas like Durban Poison (typically 15-20%) while staying below the extremes of strains like Ghost Train Haze, making it a practical choice for buyers who want genuine potency without the narrow margin for error that ultra-high-THC genetics demand.

Super Silver Haze carries a moderate difficulty rating, which in practical terms means it rewards growers who have at least one successful photoperiod grow behind them. Its Haze-heavy lineage produces tall, stretchy plants that require space management, and the 8-10 week flowering window means any environmental stress during the final weeks directly impacts that 400-600g/m² yield potential. First-time growers who want a sativa-dominant strain with a more forgiving profile would be better served by something like Blue Dream or Green Crack before moving to Super Silver Haze. That said, ILGM's germination guarantee (reflected in their 7.4/10 buyer score) makes their version a lower-risk entry point if you're committed to running this strain as an intermediate grower.

Yes, for buyers specifically targeting Haze-lineage genetics with proven yield data. Super Silver Haze's 500-700g/plant outdoor potential is higher than most comparable sativa-dominant strains at similar price points, including Jack Herer (500-600g/plant) and Amnesia Haze (600g/plant but with a longer 10-11 week flower time). The three Cannabis Cup wins this strain carries also translate to real resale and personal value — you're buying genetics with a documented performance history, not a marketing name. If your priority is CBD content above 1%, this strain's 0.1-0.5% range means it is not the right purchase regardless of price; look at ACDC or Cannatonic instead.

You can buy Super Silver Haze seeds from seven seedbanks: Seedsman, ILGM, Crop King Seeds, Herbies Seeds, MSNL, Royal Queen Seeds, and Seed City. For buyers prioritizing verified genetics and breeder documentation, Royal Queen Seeds is the strongest option as a direct-source breeder. For buyers who want the best-rated customer experience with a germination guarantee suited to this strain's moderate difficulty, ILGM's 7.4/10 score makes them the top-rated reseller option. Crop King Seeds at 7.2/10 is the best choice for Canadian buyers looking to minimize shipping time. Herbies Seeds and Seed City are worth checking for smaller pack sizes if you want to test Super Silver Haze feminized seeds before purchasing in bulk.
