Poison Inferno (Feminized Seeds)
Lineage: Durban Poison × Dante’s Inferno
Poison Inferno: Sharp, Upright Energy Balanced by Dark, Modern Calm
Poison Inferno is a meeting point between heritage and modern breeding—an intentional blend of clarity and weight. Durban Poison brings a long, respected history, tracing back to South African landrace selections known for upright growth, narrow leaf structure, and a crisp, unmistakable presence in the garden. Dante’s Inferno, by contrast, represents a newer wave of genetics, valued for darker fruit expression, visual intensity, and a composed, deliberate growth style.

Dante’s Inferno comes in like a counterweight. Darker, heavier, more deliberate. It doesn’t rush, and it doesn’t sprawl. When these two meet, the result isn’t chaos—it’s balance. Poison Inferno feels energized without feeling wild, expressive without becoming difficult. It’s a cultivar that rewards attention, but it doesn’t punish you for stepping away.
In veg, this plant makes its intentions clear early. The main stem climbs with purpose, branches space themselves cleanly, and the overall frame forms tall and upright without feeling flimsy. You’ll recognize the Durban Poison influence immediately—but you’ll also notice how Dante’s Inferno quietly keeps everything in check. It’s one of those plants that’s easy to “read,” which makes training feel intentional instead of reactive.
Aroma Profile — Sharp Anise Spice, Dry Citrus Peel, Dark Herbal Undertones
Poison Inferno announces itself through aroma long before harvest. Early flower is all about sharp anise spice and dry citrus peel—that classic Durban edge that feels crisp, bright, and almost electric in the room. The scent doesn’t hang low; it moves. You catch it as you walk past the canopy.
As flowers mature, things deepen. Dante’s Inferno starts to show through with dark herbal tones that sit underneath the brightness and slow it down. By mid to late flower, the profile feels layered rather than sharp—still lively, but grounded. After cure, those edges smooth out even more, settling into a confident, well-rounded aroma that feels intentional instead of aggressive.
Poison Inferno Flavor Profile — Toasted Herbs, Bitter Citrus Rind, Mineral Earth
The flavor leans more grounded than the aroma might suggest. The first pull usually brings toasted herbal notes, followed by a bitter citrus rind quality that gives the profile shape and tension. On the finish, a mineral, earthy tone shows up—quiet but steady—tying everything together.
Nothing overlaps or fights for attention. Each note has its moment, then steps aside. It’s a flavor profile that feels thought-through, not crowded.
How Poison Inferno Grows — Tall, Responsive, and Surprisingly Cooperative
Vegetative Behavior & Canopy Formation
Poison Inferno feminized seeds grow tall and upright, with moderate internodal spacing that makes light management easier than you’d expect from a vertical cultivar. It responds well to topping, LST, and ScrOG, especially if you redirect that upward energy early. Branches stay flexible during veg and tend to hold their position once trained.
Durban Poison supplies the drive. Dante’s Inferno supplies the discipline. Together, they create a plant that works with structured layouts instead of constantly challenging them.
Flowering Traits & Development
Once flowering begins, calyxes stack cleanly along the branches, forming elongated bud sites with clear definition. Trichomes build steadily across the cycle rather than all at once, giving flowers texture early and density later. Stretch lands in a manageable window—typically 1.4×–1.7×—so height control is more about planning than problem-solving.
Indoors, most runs finish in 9–10 weeks. Outdoors, harvest usually falls late September into early October, depending on climate. The plant holds its posture well and doesn’t lose composure when conditions shift slightly.
Yields & Visual Appeal — Tall Colas with Clean, Confident Definition
Bud Structure & Aesthetic Traits
Poison Inferno feminized seeds produce elongated buds with clear calyx separation and consistent trichome coverage. Color expression usually stays in lighter to medium greens, sometimes picking up darker accents late in flower.
What growers tend to notice:
-
Elongated, well-defined bud structure
-
Even stacking along branches
-
Consistent resin coverage
-
Clean contrast between form and frost
-
A sharp, finished look after cure
Garden & Production Output
Yields are dependable, especially when vertical growth is guided early. The natural structure works just as well for single-cola-focused grows as it does for trained, multi-top canopies, giving you flexibility depending on how you like to run your room.
