The Cross
Diamond Chem is not a polyhybrid experiment. It is a calculated saturation of one plant through convergent lineage.
Stardawg is Chem 4 crossed to Tres Dawg, and Tres Dawg is a worked Chem D line. So pairing Chem D as the mother with Stardawg as the father stacks her from the direct maternal side and again through the grandfather. The arithmetic comes out around 72% Chem D, 25% Chem 4 and a 3% trace of Afghani holding the base.
The Parents
Everything starts at Deer Creek Amphitheatre in Noblesville, Indiana, June 1991, where a seventeen year old Greg Krzanowski paid five hundred dollars for an ounce of Dog Bud. Thirteen seeds came out of that ounce and built the entire American gas market.
Chem D was number six, and she did not get popped until 2001. Where the 91 cut established the Chemdog name, the D went somewhere else entirely, and breeders have been arguing about how to describe it ever since. It is not terpene driven in the usual sense. It comes from volatile sulfur compounds, the same chemical class behind skunk spray, which work at parts per billion. They go through plastic. They defeat carbon filters. They announce themselves whether you want them to or not.
Stardawg, from JJ NYC at Top Dawg Seeds, is the structural half. Chem D on her own is a nightmare to run, floppy and vine like and needing support from week one. The Kate Upton cut brings the chassis.
What’s In The Pack
Ten regular photoperiod seeds, males included. With this much Chem D concentration it is unusually valuable as a pollen source. The hunt is for the plant that holds the mother’s character on a frame that stands up without a trellis. The Kate Upton side also carries a purple recessive that turns up in a minority of plants.
In The Garden
62-70 days from flip. Moderate difficulty, high yield. Chem D is a hungry line and will show you a deficiency before most plants would. Odor control is a planning problem with this one, not an afterthought.







Flowering since around July 1. Outdoors only
Popped 2. 1 male 1 female. She is nice and frosty. I bred her to another frosty monster.
11/13 seed to harvest, week 7-8 flower ,
Gorgeous plants – once past a finicky seedling phase.
I bought on one of the auctions so didn’t pay as much
