Take Purple Urkle, the Emerald Triangle purple keeper that most of California's colour reputation rests on, and put it over T-1000, Red Beard's pick out of Old Family Purple, and the first CSI Humboldt / CSI Portland release. That is Purple Urkle x T 1000. CSI breed off held clones rather than off seed stock, which is why the parents named on the pack are the actual plants and not their descendants.
Purple Urkle x T carries a 1000 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.
Written this way, Purple Urkle is the mother and T-1000 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 Mendocino Purps selection pulled out of the Emerald Triangle around 1990. Dense purple flower in a closed canopy is where mould starts.
- Father: T-1000. Red Beard's selection out of CSI's Old Family Purple, and the first CSI Humboldt / CSI Portland collaboration. Parentage: a selection from Old Family Purple, which is Triangle Kush x Purple Urkle. Appreciates steady feeding rather than a boom-and-bust schedule.
- 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. Sweet grape and dark berry over earthy skunk, myrcene-dominant from the Purple Urkle side, against juicy grape and sweet cream over pine needles and skunky diesel, with musky earth and a touch of spice from the T-1000 side.
- The Taste. Grape and berry turning earthy and musky up front, turning to cream and grape into pine and light diesel, earthy at the end through the exhale.
How the two sides differ
- Timing splits the pack. One parent wants around eight weeks indoors, inside a seven to nine week window, the other roughly fifty-six to seventy days, with many growers looking at week nine. Expect the fast plants down well before the slow ones are ready.
- The smell is a negotiation. Sweet grape and dark berry over earthy skunk, myrcene-dominant on one side against juicy grape and sweet cream over pine needles and skunky diesel, with musky earth and a touch of spice on the other. Neither wins outright in every seedling.
- Build. On the Purple Urkle side: compact and indica-built; deep purple colour hardest where night temperatures drop late. On the T-1000 side: indica-leaning at roughly seventy-thirty, medium height, stacking dense spear-shaped resinous colas. Select early rather than trying to train your way out of it.
- Opposite ends. Purple Urkle is reported as settled and unhurried; the heavy, physical end; T-1000 as calm rather than busy; body-heavy and relaxing. 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. Purple Urkle is compact and indica-built; deep purple colour hardest where night temperatures drop late. T-1000 is medium-sized and about seventy percent indica, stacking resinous spear-shaped colas.
- Vegetative Phase. Top or train before you flip rather than chasing the canopy afterwards.
- Flowering Time. The parents are not on the same clock. Purple Urkle runs around eight weeks indoors, inside a seven to nine week window, T-1000 roughly fifty-six to seventy days, with many growers looking at week nine. Judge each plant on trichomes rather than pulling the room together.
Effects and Experience
- The Mind. Growers describe Purple Urkle as settled and unhurried; the heavy, physical end.
- The Body. T-1000 is reported as calm rather than busy; body-heavy and relaxing, and that is the side supplying the weight here.
In the pack
Feminized seeds from Humboldt CSI. Their library is clones first and crosses second, which is why the names on their packs read like a list of plants rather than a list of products. Sold as authentic Humboldt CSI.
