Diesel cannabis seeds are a family of fuel-forward hybrids built around Chemdawg and Sour Diesel genetics — sharp, citrus-diesel terpenes with energetic, sativa-leaning effects. We carry six diesel-family strains from Azarius, split between feminised photoperiod and autoflowering versions. Good range whether you want heavy indoor yields, a fast outdoor turnaround, or your first grow. Shop diesel seeds from a smartshop that's been here since 1999.
Buy Diesel Cannabis Seeds — Range Guide
Diesel seeds produce plants with the signature fuel-and-lemon terpene profile that traces back to the original 1990s New York Sour Diesel line. Our six-strain range covers the two main diesel lineages: pure Sour Diesel (Chemdawg × Super Skunk) and the Bruce Banner / GG4 hybrids that cross diesel genetics with OG Kush or Chem Sis. If the smell you're after is fuel, citrus peel and a bit of pine, this is the shelf you want.
Strain Comparison — Pick by Format and Turnaround
The quickest way to choose is format first (photo vs auto), then potency. Autos finish in 8–10 weeks from seed with no light-schedule management; photoperiods need a 12/12 flip but reward you with bigger yields.
| Strain | Format | THC | Seed to harvest | Good for |
|---|---|---|---|---|
| Sour Diesel | Feminised photo | 22–25% | 10 weeks flower | Growers who want the classic fuel terpene |
| Bruce Banner | Feminised photo | 20–29% | 9–10 weeks flower | Heavy-yield hunters, intermediate growers |
| GG4 | Feminised photo | 27%+ | 8–9 weeks flower | Resin chasers who want trichome-heavy buds |
| Sour Diesel Auto | Autoflower | Mid-range | 70–77 days | First-time buyers, balcony growers |
| Bruce Banner Auto | Autoflower | 21–26% | 8–10 weeks | Potency without the light-timer hassle |
| GG4 Auto | Autoflower | 18–24% | 8–10 weeks | Small spaces, stealth grows |
What We Carry
- Sour Diesel (feminised) — the purist's pick. Chemdawg × Super Skunk, 22–25% THC, sharp lemon-diesel nose.
- Bruce Banner (feminised) — OG Kush × Strawberry Diesel. The big yielder, with a sweet-earthy twist on the fuel base.
- GG4 (feminised) — Gorilla Glue #4. Triple cross of Chem Sis, Sour Dubb and Chocolate Diesel, the most resin-heavy option we stock.
- Sour Diesel Auto — 70/30 sativa auto with the original 1990s NY terpene profile compressed into a 10–11 week cycle.
- Bruce Banner Auto — same parents as the photo version plus Ruderalis, 21–26% THC in 8–10 weeks.
- GG4 Auto — compact, piney, fruity finish. Good in a 60×60 tent.
How to Choose Your Diesel Seeds
First-time buyer? Order a 3-pack of Sour Diesel Auto or GG4 Auto. Autos forgive scheduling mistakes and you'll be smelling your first harvest inside 11 weeks. No light flip, no photoperiod management, and the plants stay small enough for a cupboard setup.
Got a tent and a timer already? Buy the feminised photos. Bruce Banner is where we'd point growers who want the biggest haul per plant — it responds well to basic LST and pushes 600+ g/m² in competent hands. GG4 is the one to shop if you care more about resin than yield; the trichome coverage is genuinely silly. Sour Diesel photo is the connoisseur pick — leaner yield than Banner, but the terpene profile is the benchmark.
Experienced growers buying in volume: the 10-seed packs are where the value sits. When in doubt, start with Bruce Banner — it's the most beginner-tolerant of the three photoperiods and the sweet-diesel profile is an easy sell to anyone you share with.
Frequently Asked Questions
What's the strongest diesel strain you sell?
GG4 tops the range at 27%+ THC, with Bruce Banner close behind at 20–29%. Both are feminised photoperiods — the autos sit a few points lower but finish faster.
Should I buy autoflower or feminised photoperiod diesel seeds?
Autos if you want simplicity and speed (8–11 weeks, no light schedule). Feminised photos if you want maximum yield and potency and you've got a tent with a timer. First grow? Go auto.
Do Bruce Banner and GG4 count as diesel strains?
Yes. Bruce Banner crosses OG Kush with Strawberry Diesel, and GG4 is bred from Sour Dubb and Chocolate Diesel. Both carry the fuel-forward terpene profile that defines the diesel family.
Which diesel seed is best for beginners?
Sour Diesel Auto or GG4 Auto. Autoflowers remove the photoperiod management that trips up first-time growers, and both finish in under 11 weeks from seed. Start with a 3-pack.
How many diesel seeds should I order?
Singles to test genetics, 3-packs for a first real grow, 5 or 10-packs if you're running a tent regularly. The 10-packs give the best per-seed value across the Bruce Banner, GG4 and Sour Diesel lines.
