Every seed line here goes back to the Chemdog 91 cut I’ve held since 1995. Most of them are crossed to the Chemdog 91 Bx3 stud, a few to the Bx2. The mother of each cross decides how the plant grows. These are the notes from the packs, line by line, so you can plan the room before you pop anything.
Start with the seeds
Every pack is 13 regular seeds, not feminized. You get males and females, which is what you want if you plan to hunt or breed. If you would rather skip the hunt, the breeder’s cuts are the plants I already kept, as rooted clones. New to popping seeds? Use the paper towel method.
Plan for stretch before you flip
The Bx3 male usually tempers extreme stretch. Not always. The mother has the last word.
- Stretch hard: Chemnesia stretches like the mother. Pole Dog stretched well on most plants tested. Modified Chem puts on a significant stretch in the first three weeks of flower. Schism runs medium to high. Chem Fuego and Bohemian Highway put on a fair amount.
- Stay short: Hunza Valley 91 is short with no stretch, a good fit for a low tent. Twin Peaks v2 stays bushy with minimal stretch. Chem Cornelian stretches little. Double Krush has a medium-short stretch and fits tents and low ceilings. Chasca runs medium to low, a realistic indoor sativa. Dog Patch runs low to medium.
Top and train the stretchy ones early
On the lines that stretch, spread the canopy before flower. Chemnesia responds well to topping and low-stress training, which turns the stretch into bud sites instead of one dominant cola. Top Bohemian Highway early and trellis it. On the Diesel Therapy breeder’s cut, train or top it before flower, or the stretch goes into height rather than sites. Hunza Valley 91 rewards topping and light LST early, then wants to be left alone.
Put support in before the weight comes
Some of these finish heavy enough to fold a branch.
- Raffi Dog puts very heavy flowers on taller plants. Get stakes, a trellis layer or a net in place before stretch finishes, not after the colas start to lean.
- Schism has heavy, upright branching that wants support.
- Modified Chem grows tall and needs a trellis for the terminal colas.
- Dog Roller grows fat, chunky buds that weigh the plant down. Support the branches late.
Others hold their own. Sunshine Biscuits grows stocky with strong side branching and needs minimal support. Hunza Valley 91’s thick branching holds weight in most rooms. Chem D builds a sturdier frame than most of the Chem family.
Growing in humidity
Pole Dog grows large flowers that held up against mold in testing. That’s a real advantage in a humid room, where a dense flower that size would normally be a risk.
Hunting the pack
Regular seeds mean variation, and some lines vary more than others. Pole Dog’s phenotypes vary more than most crosses here, in stretch and in expression. On Chem Fuego, select for the early finishers. When I find the one worth keeping, it becomes a breeder’s cut, like Chemnesia #4.
The cut herself
The Chemdog 91 clone is a different job from her crosses. She flowers in 63 to 70 days. She is not a beginner plant. She needs some experience. Yield is average, and I don’t keep her for weight. Her sister Chem D is the easier one: beginner-friendly, a better yield than her sisters, and 63 to 70 days. The whole line is laid out on the Chemdog 91 page.
Common questions
Are Chemdog 91 crosses hard to grow?
No. All of my genetics are easy to cultivate with vigorous growth. The Chemdog 91 cut herself is the exception: she needs some experience and is not a beginner plant.
Do Chemdog 91 crosses stretch?
It depends on the mother. Chemnesia, Pole Dog and Modified Chem stretch hard. Hunza Valley 91 has no stretch, and Twin Peaks v2 and Chem Cornelian stretch very little.
Are the seeds feminized?
No. Every pack is 13 regular seeds, males and females, so you can hunt and breed.
How long does the Chemdog 91 cut flower?
63 to 70 days. Yield is average. I don’t keep her for weight.
