Birthday Cake x Purple Urkle 103 puts Birthday Cake over Purple Urkle. One is Girl Scout Cookies crossed to Cherry Pie, and one of the cleanest dessert profiles anyone made; the other is a select phenotype of Mendocino Purps out of the Emerald Triangle around the turn of the 1990s. Two very different plants, and the point of the cross is what sits between them. 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.

Birthday Cake x Purple Urkle carries a 103 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, Birthday Cake is the mother and Purple Urkle 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: Birthday Cake. Girl Scout Cookies crossed to Cherry Pie, and one of the cleanest dessert profiles anyone made. Parentage: Girl Scout Cookies x Cherry Pie.
• Father: Purple Urkle. The Emerald Triangle purple keeper that most of California's colour reputation rests on. Dense purple flower in a closed canopy is where mould starts.
• How to read it. Everything below splits into what one parent gives and what the other does. Plants that take from both are the ones to keep.

Flavor and Aroma Profile

Expect the profile to move plant to plant rather than settle.

• The Aroma. Sweet vanilla that genuinely does read as cake, turning slightly skunky when the buds are broken open from the Birthday Cake side, against sweet grape and dark berry over earthy skunk, myrcene-dominant from the Purple Urkle side.
• The Taste. Sweet vanilla on the inhale with a skunky edge behind it up front, turning to grape and berry turning earthy and musky through the exhale.

What each side brings

• What to budget. The documented side, Purple Urkle, runs around eight weeks indoors, inside a seven to nine week window. Set the room to that and let the plants correct you.
• Two noses, one pack. Birthday Cake contributes sweet vanilla that genuinely does read as cake, turning slightly skunky when the buds are broken open. Purple Urkle contributes sweet grape and dark berry over earthy skunk, myrcene-dominant. Which dominates is the main thing that varies.
• Two frames in one pack. Birthday Cake is indica-leaning with heavy resin production. Purple Urkle is compact and indica-built; deep purple colour hardest where night temperatures drop late. Decide which suits your room before you flip, because you get both.
• They pull differently. Growers put Birthday Cake at indica-dominant and physically relaxing and Purple Urkle at settled and unhurried; the heavy, physical end. 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. Birthday Cake is indica-leaning with heavy resin production. Purple Urkle is compact and indica-built; deep purple colour hardest where night temperatures drop late.
• Before the flip. Decide the shape now. These lines do not tidy themselves up once they are running.
• 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 Birthday Cake as indica-dominant and physically relaxing.
• The Body. Purple Urkle is reported as settled and unhurried; the heavy, physical end, 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. Real Humboldt CSI stock, not a copy.
