Black Haze Seeds

The key purchasing difference comes down to yield ceiling and format flexibility. Black Haze feminized seeds are available from Crop King Seeds, Beaver Seeds, and Mary Jane's Garden, and they deliver the strain's full 400-500g/m² indoor yield potential. The autoflower version — stocked by Exotic Seed, Delicious Seeds, and World of Seeds — completes in 8-10 weeks from seed regardless of light schedule, making it the better buy for growers running multiple annual cycles or working in regions with shorter outdoor seasons. If maximizing per-plant output from Black Haze's Colombian genetics is the priority, feminized is the stronger purchase. If speed and scheduling flexibility matter more, autoflower delivers the same core genetics with a simpler run.

Black Haze seeds are verified at 18-22% THC across both feminized and autoflower formats. This puts the strain in the moderate-high potency bracket — meaningfully stronger than entry-level strains but not at the extreme end of the market. For buyers comparing strains in this THC range, Black Haze's sativa-dominant 60/40 ratio means the potency profile leans toward cerebral rather than sedative. CBD content is insignificant, so buyers seeking CBD-balanced options should look elsewhere. The 18-22% range is consistent across the seedbanks carrying this strain, including Delicious Seeds and World of Seeds.

Black Haze is rated intermediate difficulty, which means it's not the ideal first purchase for a first-time grower. The triple-lineage genetics — Purple Haze, Columbian Gold, Columbian Black — produce a more complex plant than single-origin strains, and the sativa-dominant structure typically requires more management than indica-heavy alternatives. That said, the intermediate rating doesn't mean advanced-only. Growers with one or two successful grows already completed will find Black Haze very manageable. If you're a first-time buyer, it may be worth starting with a simpler strain before investing in these seeds; if you have some experience, Black Haze is a well-documented strain with solid seedbank support across six sources.

Black Haze seeds are currently available from six seedbanks. For feminized seeds, Crop King Seeds, Beaver Seeds, and Mary Jane's Garden are the go-to sources. For autoflower seeds, Exotic Seed, Delicious Seeds, and World of Seeds carry the strain — with Delicious Seeds being notable as the original breeder. When deciding where to buy Black Haze seeds, compare pack sizes (typically ranging from 3 to 10 seeds per pack depending on the seedbank), per-seed pricing, and germination guarantee terms. Crypto payment options are available through several of these seedbanks and can reduce the total cost, particularly on larger orders.
