Auto Chemdog

Auto Chemdog Cannabis Seeds by Auto Seeds

Auto Chemdog is a feminized autoflowering hybrid strain that goes from germination to harvest in just 60–65 days, producing dense, trichome-coated buds with up to 21% THC. Bred by Auto Seeds from their proprietary Auto #1 ruderalis crossed with the legendary original Chemdog clone, this strain packs serious potency into a fast, forgiving grow cycle. If you want Chemdog's famously intense cerebral effects without the photoperiod fuss, this is your seed.

Why Auto Chemdog Seeds Deserve a Spot in Your Grow

Auto Chemdog takes one of the most storied genetics in cannabis — the original Chemdog clone, a strain with genuinely mysterious origins and a reputation for face-melting potency — and wraps it in an autoflowering package that practically grows itself. The ruderalis genetics come from Auto Seeds' own Auto #1 line, purpose-bred to pass on autoflowering traits without watering down the good stuff. The result is a plant that doesn't care about your light schedule. Set it, water it, feed it, and 60–65 days later you're trimming sticky buds.

We've carried Auto Seeds for years, and their breeding programme is consistently solid. They focus on keeping autoflowering lifespan short while maintaining the flavour and potency profiles of the photoperiod parents. Auto Chemdog is one of their better examples — the THC content reaches 21%, which is genuinely impressive for an auto. Most autos in that speed range sit around 15–18%. The extra few percentage points are noticeable.

The honest limitation here: yield. At 280–350g/m² indoors, Auto Chemdog won't compete with a photoperiod Chemdog given a long veg cycle and a SCROG net. That's the trade-off for the speed. You're harvesting in two months instead of four. For many growers — especially those running perpetual harvests or working with limited space — that maths works out better anyway. Outdoors, yields climb higher, and you can run multiple cycles between May and early October.

Auto Chemdog Grow Traits and Specifications

Flavour, Aroma, and What to Expect from Auto Chemdog Buds

The flavour profile on Auto Chemdog is where the Chemdog parentage really shines through. Expect a layered, complex smoke — spicy on the inhale with a distinct citrus bite, then that unmistakable skunky funk on the exhale that lingers in the room (and on your clothes, fair warning). It's not a subtle strain. If you're growing in a tent without a carbon filter, your neighbours will have opinions.

Visually, mature Auto Chemdog plants are genuinely good-looking. Vivid green foliage disappears under a thick white trichome blanket as the buds fill out. The bud structure leans toward Kush-style density — tight, pistil-heavy nuggets that trim up nicely. According to a terpenoid profiling study published in the Journal of Cannabis Research, Chemdog varieties typically express a terpene profile dominated by myrcene (4.2 ± 1.1 mg/g) and limonene (0.9 ± 0.2 mg/g), which aligns with the spicy-citrus character you'll taste in the smoke (Hazekamp et al., PMC5436332).

The effect is a two-stage experience. It starts with a strong, reflexive cerebral hit — your thoughts shift, your perception sharpens, and there's a definite mind-altering quality that the Chemdog line is famous for. That transitions into a full body relaxation that settles in progressively. At 21% THC, this isn't a strain to underestimate. One or two hits is enough for most people to feel it fully. If you're used to milder autos, approach with a bit of respect.

How to Grow Auto Chemdog Seeds

1. Germinate your Auto Chemdog seeds using the paper towel method or directly in a small pot of moist, airy soil. Taproots typically emerge within 24–72 hours.
2. Transplant into your final container early — autos don't respond well to transplant shock mid-cycle. A 10–15 litre fabric pot is the sweet spot for indoor grows.
3. Run an 18/6 or 20/4 light schedule from day one. Since Auto Chemdog is autoflowering, it doesn't need a light cycle change to trigger flowering. More light hours generally means more yield.
4. Keep feeding moderate during the first 2–3 weeks (seedling stage), then increase nutrients as the plant enters pre-flower around day 20–25. Auto Chemdog responds well to balanced NPK feeds without heavy supplementation.
5. Watch for the trichome development from around day 45 onwards. Harvest when trichomes shift from clear to milky-white for a more cerebral effect, or wait for some amber trichomes if you prefer a heavier body stone.
6. Expect the full cycle — germination to chop — within 60–65 days. Outdoor growers can stagger plantings from May through July for multiple harvests before October.

Auto Chemdog vs Photoperiod Chemdog: Which Should You Grow?

This is the question we get asked most with any auto version of a famous strain. Here's the honest breakdown:

If you're running a small tent, growing for the first time, or want fast turnarounds for a perpetual setup, Auto Chemdog is the better pick. If you've got the space, patience, and experience to maximise a photoperiod plant, you'll pull more weight and slightly higher potency from the original. Both deliver that signature Chemdog flavour and cerebral punch — the auto just gets you there faster with less fiddling.

What Makes Auto Seeds a Reliable Seed Bank

Auto Seeds have been specialising in autoflowering genetics for over a decade, and their breeding approach is straightforward: cross proven photoperiod genetics with their proprietary Auto #1 ruderalis line, then stabilise until the offspring consistently deliver both the autoflowering trait and the parent strain's character. It sounds simple, but getting a 21% THC auto that finishes in 65 days takes serious selection work. We've stocked their range since they launched, and germination rates have been consistently above average. The seeds are well-packaged and clearly labelled — no mystery packs, no unlabelled freebies that might be anything.
