White Sour
Loompa held this cut in a Northern California vault for twenty years and eventually renamed it Underdawg OG to separate it from the East Coast Headbands. Greenpoint got it under a Stardawg male from the same batch as Top Dawg’s Kate Upton release. Pre Cookies gas on vintage OG bones.
Loompa’s Headband x Stardawg (Kate Upton batch) | Regular photoperiod | 10 seeds | 62-70 days | Born-on: Jan 2026
The Cross
Two clone only legends collapsed into a regular seed F1. Roughly half vintage OG through the mother, a quarter Chem 4 and an eighth Chem D through the father, with an Afghan chassis underneath.
The market drowned itself in cake batter. White Sour is the other thing, the jars people have been quietly keeping for twenty years, put back into seed form where it can be grown instead of traded.
The Parents
Headband was never a single strain. It was a regional codename. By the early 2000s an elite OG Kush cut had moved out of Southern California into the Bay Area and the Emerald Triangle, and the growers up there renamed it for distance and for accuracy. That umbrella fractured into several regional Headbands: Mandelbrot’s 707 out of Mendocino, the East Coast Daywrecker on the I-95 lane, and the Loompa Farms cut.
Loompa’s was the OG leaning expression, tall with golf ball nugs running up the stem. He eventually re-christened it Underdawg OG to separate it from the East Coast Headbands tied to the Chem and Diesel lanes, and it has stayed clone only ever since.
Stardawg is Chem 4 crossed to Tres Dawg from JJ NYC at Top Dawg Seeds. This male came out of the same batch as the Kate Upton release.
What’s In The Pack
Ten regular photoperiod seeds, males and females segregating. Selection markers worth using: thick deeply ribbed stalks with an immediately offensive stem rub, and cut anything thin or vine like. Stretch should plateau around 1.5x with tight internodes, so cut anything past 2.5x or stringing out. Resin should be creeping down the petioles by week five. At the end the keeper reveals itself when the calyxes blow out and the trichomes turn tacky. Cut leafy plants that never swell. Rooted clones of selections 65 and 68 are offered separately when available.
In The Garden
62-70 days, roughly nine weeks indoors. Intermediate, medium yield that stacks heavy late. Trellis required.

Fernando Sanchez
Was able to get some of these pks when they came out as testers. Very happy with the end product popped 8 all sprouted within 48hrs. 3 different noses one had a mint/vapor rub with strong OG on the back end another had a gasoline nose with the OG on the back end and the last was more of the OG lemon pledge smell all very frosty and resinous definitely will run it again soon Was trying to upload more than one picture but couldn’t

I grew a few shorties. Definitely very frosty. Extremely dense flowers. I took two phenos outdoor last week so I guess we’ll see what happens this fall!.
