Purple Urkle BX 1 (Purple Urkle x Patient Zero) is Purple Urkle crossed to Patient Zero. Purple Urkle is a Mendocino Purps selection pulled out of the Emerald Triangle around 1990. Patient Zero is CSI's select cut of the Purple Urkle clone crossed to Pakistani Chitral Kush, chosen out of more than a hundred seed plants. Between them they cover ground neither reaches alone. What CSI sell is access to their clone collection in seed form. The parents are the cuts themselves, not a line bred to resemble them.

The number in Purple Urkle BX 1 is a specific plant, not a decoration. Humboldt CSI grow a population out, keep the individuals worth keeping and number them, so Purple Urkle BX 1 is one identified selection rather than Purple Urkle BX in general. A pack naming a different number is a different mother.

Written this way, Purple Urkle is the mother and Patient Zero 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: Purple Urkle. A select phenotype of Mendocino Purps out of the Emerald Triangle around the turn of the 1990s. Dense purple flower in a closed canopy is where mould starts.
• Father: Patient Zero. CSI's select cut of the Purple Urkle clone crossed to Pakistani Chitral Kush, chosen out of more than a hundred seed plants. That one comes from Purple Urkle x Pakistani Chitral Kush, also written Pakistani Purple Kush. CSI also cross it out - Living Dead Girl is Patient Zero over the Forum Cookies cut.
• 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

Two distinct smells, and a pack will give you both plus everything between.

• The Aroma. Grape and berry with a musky, skunky floor under it from the Purple Urkle side, against grape and dark berry off the Urkle side with Kush earth underneath from the Patient Zero side.
• The Taste. Grape and berry turning earthy and musky up front, turning to grape and earth, heavier than it is sweet through the exhale.

Where the parents disagree

• Timing. Purple Urkle runs around eight weeks indoors, inside a seven to nine week window, and that is the half of this cross you can actually plan around.
• Where the nose comes from. One side gives sweet grape and dark berry over earthy skunk, myrcene-dominant; the other gives grape and dark berry off the Urkle side with Kush earth underneath. Plants landing in the middle are the keepers.
• Structure varies hard here. Compact and indica-built; deep purple colour hardest where night temperatures drop late from one parent; the purple side of the CSI library, out of a hundred-plant hunt rather than a small run from the other. Plan the canopy for the taller outcome.
• They pull differently. Growers put Purple Urkle at settled and unhurried; the heavy, physical end and Patient Zero at settled and physical. Which end a plant lands on is the main variable.

Cultivation and Growth Traits

• Plant Structure. The two parents disagree here, so plan for range. Purple Urkle is a short, tight plant that colours hard once the nights cool off. Patient Zero is the purple side of the CSI library, out of a hundred-plant hunt rather than a small run.
• Vegetative Phase and Training. Open the middle out early. Light reaching the lower sites is worth more than any late correction.
• Flowering Time. Purple Urkle runs around eight weeks indoors, inside a seven to nine week window. Start checking trichomes a week before you expect to be ready.

Effects and Experience

• The Mind. Growers describe Purple Urkle as settled and unhurried; the heavy, physical end.
• The Body. Patient Zero is reported as settled and physical, and that is the side supplying the weight here.

In the 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. Humboldt CSI original genetics.
