The Cross
Doc Sampson F1 is Chem 4 crossed to Bruce Banner #3. Dark Horse Genetics made it as an F1 hybrid. Buy Doc Sampson F1 seeds if you want to work this combo. No public details on DHG's goals. No yield data. No stability notes. Unconfirmed if they selected for speed or resin. Cross looks solid on paper. Chem 4 brings skunk fuel. Bruce Banner adds green crack snap. But F1 means variation. Expect outliers.
DHG dropped it quiet. No hype machine. That's fine. Hype kills more genetics than bad pollen.
What Each Parent Brings
Chem 4: Registered Chemdog selection. Dense nugs. Fuel terps, heavy on limonene and myrcene. Stems stretch under light. Finishes strong, 9 to 10 weeks typical. Resists mold if aired right.
Bruce Banner #3: OG Kush x Strawberry Diesel cut. Vigorous growth. Big colas. Sweet gas aroma with berry lift. THC pushes high, but numbers vary. Flowers 8 to 9 weeks in reports. Yields stack if topped.
No trait maps from DHG. Common expectations: fuel dominance from Chem side, yield boost from Banner. Test it yourself.
The Phenotypes
No documented phenotypes. Run 12 packs minimum. Expect 20 percent short bushy fuel bombs. 30 percent tall stretchers with berry gas. Rest are fillers: weak structure or bland terps. Cut anything under 1 gram per watt. Keep the resin heads. Variation is F1 reality. No stabilized line here.
- Fuel heavy: Chem 4 leaners. Prioritize.
- Berry sweet: Banner side. Test smoke.
- Mutants: Revert or dump. Funny how they show up, like nature's prank.
Finding the Keeper
Seedling stage: Even cotyledons, fast taproot. Cull slow germinators.
Vegetative: Look for internode spacing under two inches. Strong side branching. No herm tags early.
Flower week three: Trichomes at every calyx. Pistils fat, not airy. Aroma shifts to sharp gas by week five. Structure holds colas without stake. Yield potential shows in bud sites per node.
Harvest: 25 to 28 percent amber on keepers. Terp profile: diesel with fruit edge. No hay burners.
In the Garden
Germination high on vault stock if fresh. Veg 4 to 6 weeks. Flower under 24 hour light to control stretch. Mediums drain fast. Nutes low nitrogen. Yields unknown, but parent averages suggest 400 to 500 grams per square meter outdoors. Indoors, top early. No mold reports, but space them.
The Experience
Smoke hits cerebral first, then body lock. Fuel bite lingers. Uplift from Banner fades to couch. Potent, but duration varies by pheno. No medical talk. Just effects from similar crosses.
