Forbidden Fruit x Chemdog 91 brings Forbidden Fruit together with Chem 91. The first is the Cherry Pie and Tangie cross that is all about the fruit; the second, the SKVA cut - the original Chemdog '91 and the clone the family takes its name from. Two lines that were never going to produce a quiet plant. Humboldt CSI work almost entirely from clones they hold themselves, so both sides of this are the real thing rather than a seed-line approximation of it.
Forbidden Fruit x Chemdog carries a 91 because selections get numbered to stay distinguishable once they leave the room they were made in. It marks this exact mother, and it is the part of the name worth reading closely.
Order matters in a cross name. In Forbidden Fruit x Chemdog 91 the Forbidden Fruit side supplied the seed and Chem 91 the pollen, and the reciprocal - the same two plants the other way round - is a separate breeding decision with its own results.
Genetic Lineage
- Mother: Forbidden Fruit. Cherry Pie crossed to Tangie - dark cherry against bright citrus. It traces back to Cherry Pie x Tangie. Rated an easy grow that does not need constant attention.
- Father: Chem 91. The SKVA cut - the original Chemdog '91 and the clone the family takes its name from. Parentage: one of thirteen seeds from a bag bought at a Grateful Dead show in 1991. Skunk VA was given a cut in 1995 and has held it since, which is why the line survives.
- Why it is worth a pack rather than a look. The two sides are far enough apart that seedlings genuinely differ. That range is the product.
Flavor and Aroma Profile
Two profiles that stay distinguishable rather than collapsing into one.
- The Aroma. Dark cherry and bright orange citrus from the Forbidden Fruit side, against pungent turned earth and diesel with pine and citrus sitting behind from the Chem 91 side.
- The Taste. Cherry and passionfruit with citrus over the top up front, turning to greasy and mouth-coating, fuel then earth and pine, finishing sour through the exhale.
How the two sides differ
- Two different harvest dates. Nine to ten weeks indoors for Forbidden Fruit, sixty-three to seventy days for Chem 91. Judge each plant on trichomes rather than pulling the room together.
- The smell is a negotiation. Dark cherry and bright orange citrus on one side against pungent turned earth and diesel with pine and citrus behind it on the other. Neither wins outright in every seedling.
- Structure varies hard here. Compact at eighty to a hundred and twenty centimetres indoors from one parent; loose and open rather than compact, moderate to heavy stretch, branches that soften under weight late from the other. Plan the canopy for the taller outcome.
- Opposite ends. Forbidden Fruit is reported as indica-leaning and settling; Chem 91 as alert and head-forward, sativa-leaning rather than heavy. The cross sits somewhere between and moves plant to plant.
Cultivation and Growth Traits
- Plant Structure. The two parents disagree here, so plan for range. Forbidden Fruit is compact and dense, colouring the way its Cherry Pie side does. Chem 91 is open and loose rather than tight, stretching moderately to heavily, with branches that soften under weight late in flower.
- Vegetative Phase and Stretch. Shape the plant before the flip. Correcting a frame in week six is harder work than setting it in week two.
- Flowering Time. The parents are not on the same clock. Forbidden Fruit runs nine to ten weeks indoors, Chem 91 sixty-three to seventy days. Judge each plant on trichomes rather than pulling the room together.
Effects and Experience
- The Mind. Growers describe Forbidden Fruit as indica-leaning and settling.
- The Body. Chem 91 is reported as alert and head-forward, sativa-leaning rather than heavy, and that is the side supplying the weight here.
In the pack
Feminized seeds from Humboldt CSI. Humboldt CSI are preservationists before they are breeders - most of what they release is a clone somebody has kept alive by hand for years, put into seed so it stops depending on one grower staying in the game. That is what you are buying into here. Authentic Humboldt CSI genetics.
