Durban Poison is sweaty forehead smoke. Grown right, it is still one of the most powerful things you can put in a pipe, and it has been that way for as long as anyone in this has been paying attention.
I put the Chemdog stud on her to smooth that edge. What I did not expect was what happened to the smell.
What the cross actually changed
The plan was simple. Take the energy, take the edge off.
The energy stayed. That part worked. What surprised me was that the Chemdog side did not just soften her, it moved the aroma somewhere else entirely. The dominating smell and flavour of the mother turned into something I had not seen coming.
What comes out now is gassy citrus funk over deep earthy undertones. Pungent enough that it fills the room the moment the jar opens.
That is the part no listing can tell you, because nobody else made this cross.
The mother is a landrace, not a named cross
Worth being clear about, because plenty of write-ups get it wrong.
Nobody can name a cross that made Durban Poison. She is not Something x Something. Her parents were the same plant she is. She is a landrace, a plant that settled into one part of the world and adapted there over a very long time, in her case South Africa, around Durban.
How she got out of South Africa and into everybody else’s gardens is told several different ways, and the people in those stories do not agree with each other. I was not there for any of it, so I will leave it alone. What matters here is what she brings: speed, and that hard sativa punch.
The Chemdog side
Chemdog 91 Bx3 is the stud on this one, same as most of what I put out. It is the cut I have held since 1995, backcrossed three times.
What it contributes here is structure, resin, and enough weight underneath to keep the Durban side from running away with you.
How she grows
This one needs some experience. She is not a beginner plant. Sativa vigour out of a landrace mother means she moves, and if you flip her without a plan you will be looking at the ceiling.
Flowering: 63 to 70 days.
Yield is above average. Significant vigour and frost-heavy buds. The resin comes off the Chemdog side.
13 regular seeds.
Growers running her report a stretch of roughly one and a half to two times after the flip, with speared colas and laterals that take well to topping and a screen. That is their experience rather than my numbers, but it lines up with what I would tell you: plan the height before you flip, not after.
What she smokes like
Energizing, still. That never left.
It is a soaring, cerebral thing, the kind of smoke that suits daytime and suits work. The Chemdog lineage puts a layer of physical relaxation underneath, so it does not get jittery on you the way a hard sativa can.
If you have smoked the Durban on her own and found her too much, this is the version that keeps the lift and loses the sweat.
What you will read elsewhere
Diesel Poison turns up on a fair few sites now, and the entries are a mixed bag.
The flowering time is usually right. Most have 63 to 70 days, which matches my pack, and that is rarer than it should be.
You will also see potency percentages attached to her. I do not publish those and I never will. You will see her called sativa-dominant with a number next to it. I have never published a split either. And you will find long write-ups about Durban Poison that then guess at what my cross does with her.
Nobody guessing has run this cross. I have.
Common questions
What is Diesel Poison crossed with?
Durban Poison, a South African landrace sativa, crossed with Chemdog 91 Bx3.
Is Durban Poison a cross?
Not a named one. She is a landrace, a plant that adapted in one place over a very long time, so her parents were the same landrace she is. There is no Something x Something to give you.
How long does Diesel Poison take to flower?
63 to 70 days.
Is Diesel Poison good for a beginner?
No. She needs some experience and she is not a beginner plant. Sativa vigour out of a landrace mother means she moves, and the height has to be planned before you flip.
What does Diesel Poison smell and taste like?
Gassy citrus funk over deep earthy undertones, pungent enough to fill the room when the jar opens.
What are the effects of Diesel Poison?
Energizing and cerebral, suited to daytime, with a layer of physical relaxation off the Chemdog side that keeps it from turning jittery.
What does Diesel Poison yield?
Above average. Significant vigour and frost-heavy buds, with the resin coming off the Chemdog side.
Is Diesel Poison the same as Durban Poison?
No. Durban Poison is the mother. Diesel Poison is what came out when I crossed her with the Chemdog 91 Bx3, and the aroma is not the same plant’s aroma any more.
How many seeds are in a pack?
13 regular seeds.
Where to find her
Diesel Poison comes as 13 regular seeds. If you would rather skip the hunt, the Breeder’s Cut clone is the exact plant I selected and kept from the line.
If it is the Durban side you are chasing, Chem Flyer is Durban Thai Highflyer crossed to the same Chemdog stud, and it goes somewhere different again. Chemdog 91 is the cut underneath both.
Every cross on the Chemdog seeds page runs back to the same Chemdog 91 Bx3 stud.
The lineage behind every cross here, Chem D and Chemdog 91 side by side, is on the Chem D vs Chemdog 91 page.
