Chem D x Purple Punch brings Chem D together with Purple Punch. The first is the most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel; the second, Larry OG crossed to Granddaddy Purple, and the plant that set the bar for sweet. Two lines that were never going to produce a quiet plant. These are held cuts, not recreations. CSI's entire catalogue works that way, and it is the reason their crosses are worth chasing.

Written this way, Chem D is the mother and Purple Punch the pollen donor. Reversing a cross is not a formality; which plant carries the seed shapes what comes out of the pack.

Genetic Lineage

• Mother: Chem D. The most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel. Parentage: another phenotype from the same 1991 seed lot. It is the Chem half of Giesel, and one of the most widely used Chem cuts in American breeding.
• Father: Purple Punch. A Larry OG and Granddaddy Purple cross that made grape candy a category. Parentage: Larry OG x Granddaddy Purple.
• Why these two. They are not variations on the same idea. They pull in different directions, and that spread is what makes a pack worth hunting through rather than just growing.

Flavor and Aroma Profile

The two halves stack rather than blend, which is the whole reason to run it.

• The Aroma. Chemical fuel over dark, turned earth from the Chem D side, against confected grape with berry and a muffin-like sweetness behind it from the Purple Punch side.
• The Taste. Fuel and earth, greasy and coating, finishing sour up front, turning to sweet candy-grape, vanilla and tart berry, closing on a faint earthy spice through the exhale.

What each side brings

• What to budget. The documented side, Purple Punch, runs seven to nine weeks indoors. Set the room to that and let the plants correct you.
• Where the nose comes from. One side gives chemical fuel over dark turned earth; the other gives grape candy first, then blueberry muffin and tropical punch. Plants landing in the middle are the keepers.
• Two frames in one pack. Chem D is open and loose rather than compact, wants support once the colas load. Purple Punch is short and stocky, carries its own weight; dense flower with deep purple colouring and a heavy resin load. Decide which suits your room before you flip, because you get both.
• Opposite ends. Chem D is reported as alert and head-forward rather than heavy; Purple Punch as even rather than racy; strongly indica-leaning and settling. 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. Chem D is a sprawler that needs propping once weight goes on the branches. Purple Punch is short and stocky, carries its own weight; dense flower with deep purple colouring and a heavy resin load.
• Vegetative Phase. Top or train before you flip rather than chasing the canopy afterwards.
• Flowering Time. Purple Punch runs seven to nine weeks indoors. Start checking trichomes a week before you expect to be ready.

Effects and Experience

• The Mind. Growers describe Chem D as alert and head-forward rather than heavy.
• The Body. Purple Punch is reported as even rather than racy; strongly indica-leaning and settling, and that is the side supplying the weight here.

In the pack

7 feminized seeds per pack. Feminized seeds from Humboldt CSI. What they sell is preservation work: old clones reversed into seed so the line survives past whoever is currently keeping it alive. Sold as authentic Humboldt CSI.
