Black Demon Seeds

OG Kush Power, Dark Indica Dominance

Black Demon feminized seeds deliver a potent OG Kush-lineage indica with THC testing between 18-25%, making this one of the stronger indica options available for buyers who prioritize sedating, heavy-hitting effects. Outdoor plants push 500-600g per plant across an 8-9 week flower window, giving serious cultivators a high-yield, high-potency combination that's genuinely hard to match at this price point.

Black Demon is available in feminized format, the single seed type stocked by both seedbanks carrying this strain.

Where to Buy Black Demon Seeds

Seedbank Availability

Two seedbanks currently stock Black Demon seeds online: Crop King Seeds and Homegrown Cannabis Co. Both carry the strain in feminized format only. If you're looking to buy Black Demon seeds with fast shipping and established order tracking, either seedbank ships to most major markets, but your choice between them comes down to reputation data and what each brings to this specific strain.

Comparing the Two Seedbanks

Crop King Seeds carries Black Demon feminized seeds with a verified customer review score of 7.2/10, which is a useful benchmark when weighing purchase confidence. Crop King is a Canadian-based seedbank with a long track record selling OG Kush-lineage genetics, and their germination guarantee is relevant here given Black Demon's moderate difficulty rating. Homegrown Cannabis Co does not yet have a published aggregate score for this strain on our platform, but they operate as a breeder-direct source for several of their genetics, which can matter when verifying that your Black Demon seeds carry authentic OG Kush lineage rather than a rebranded cross. For potency-focused buyers, Homegrown's lab-tested THC documentation is worth requesting before ordering, given that Black Demon's 18-25% range is wide enough that batch variation is a real factor.

Value Assessment

Black Demon's specs justify a mid-to-upper price tier for indica feminized seeds. The 400-500g/m² indoor yield combined with a sub-9-week flower time puts it ahead of slower OG Kush phenotypes like OG Kush itself, which commonly runs 8-10 weeks for comparable indoor output. For buyers comparing Black Demon against other high-THC indicas in the 20-25% range, such as Bubba Kush or Skywalker OG, the outdoor yield of 500-600g per plant is a strong differentiator if you have garden space. The 0.1-0.5% CBD is low but measurable, so medical buyers who want certified CBD content should request a certificate of analysis from whichever seedbank they order through rather than relying on the listed range alone.

Black Demon Seeds: Frequently Asked Questions

What THC level can I expect from Black Demon seeds?

Black Demon seeds test between 18-25% THC depending on the phenotype and growing conditions. That's a meaningful range, so buyers chasing the upper end should request batch-specific lab results from Crop King Seeds or Homegrown Cannabis Co before purchasing. Crop King Seeds holds a 7.2/10 customer score for this strain, which suggests consistent but not exceptional phenotype uniformity across their stock.

Is Black Demon a good strain for beginner growers?

Black Demon is rated moderate difficulty, which means it's manageable but not forgiving of neglect. First-time growers who want an OG Kush-lineage indica with less technical demand would be better served by a beginner-rated strain. If you're set on Black Demon, Crop King Seeds offers a germination guarantee that provides some protection on your initial investment given the moderate grow complexity.

Is Black Demon worth the price compared to similar strains?

At 500-600g per outdoor plant and an 8-9 week flower time, Black Demon competes well against other OG Kush-derived indicas like Bubba Kush, which typically yields less per plant outdoors. The 18-25% THC range also puts it above mid-shelf indicas in the 15-18% bracket. For buyers comparing price-per-gram of flower potential, Black Demon's outdoor yield makes it one of the stronger value propositions in the OG Kush lineage category.

Where can I buy Black Demon seeds online?

Black Demon feminized seeds for sale are currently available through two seedbanks: Crop King Seeds, which carries a verified 7.2/10 customer review score for this strain, and Homegrown Cannabis Co. Both ship to most major markets. If verified OG Kush genetics are your priority, compare each seedbank's lineage documentation before placing your order, since Black Demon's market positioning depends heavily on authentic source genetics.
