Auto Critical HOG Cannabis Seeds by T.H. Seeds
Auto Critical HOG is a feminized autoflowering cannabis seed from T.H. Seeds that crosses Tennessee HOG with Basque Country Critical Mass to produce a mostly indica plant with serious yield potential. She's one of those strains that does the heavy lifting for you — low maintenance, thick buds, and a flowering cycle that wraps up in 65–70 days from seed. Available in packs of 3 or 5 seeds.
Pack Sizes
| Pack | Seeds | SKU |
|---|---|---|
| 3 Seeds | 3 feminized autoflower seeds | CSTS0090 |
| 5 Seeds | 5 feminized autoflower seeds | CSTS0018 |
If you're running a single tent and want to test the genetics first, the 3-pack is sensible. Go with 5 if you want a full canopy or some backup seeds for a second run.

Running Auto Critical HOG indoors? She throws off a big, sticky aroma once those buds start swelling. A carbon filter and extraction fan setup is practically mandatory if you're growing in a tent or spare room. Pair this strain with a complete grow tent kit and you'll have ventilation sorted from day one. A magnifying loupe is also worth grabbing — checking trichome development on those dense, resin-coated buds will help you nail the harvest window.
Why Auto Critical HOG Is the Best Autoflower for First-Time Growers
We get asked constantly: "What's a good first seed to grow?" Auto Critical HOG is one of the names that comes up every time, and for good reason. She's genuinely forgiving. Miss a feed, run your lights slightly off, forget to pH your water once — she shrugs it off. That resilience comes from the Critical Mass side of her genetics, a strain that's been bred for consistency across generations.
The Tennessee HOG parent brings the muscle. That's where the dense bud structure and heavy resin production come from. When you combine that with the reliability of Critical Mass and wrap it in autoflowering genetics, you get a plant that basically runs on autopilot. No light schedule changes, no photoperiod stress — she flowers when she's ready, typically around day 65–70 from germination.
The honest limitation? She's not the fastest autoflower on the market. Some autos finish in 55–60 days. Auto Critical HOG takes her time — 65–70 days is the realistic window. But that extra week or so pays off in yield. We're talking 350–550 g/m² indoors, which is genuinely impressive for an auto. Compare that to something like a Quick One or Easy Bud, which might finish faster but typically produce 200–325 g/m². The maths speaks for itself.
Growing Auto Critical HOG: What to Expect
Auto Critical HOG is a stocky, expansive plant that fills out laterally. Indoors she'll reach about 100 cm, which is manageable in most tents — an 80x80 cm space handles her comfortably, though you could fit two in a 120x120. Outdoors, under good sun and in decent soil, she stretches to around 120 cm.
- Germinate your Auto Critical HOG seeds using the paper towel method or directly in a small pot of lightly moistened seedling soil. Taproots usually appear within 24–72 hours.
- Transplant into her final pot early — autos don't love being moved. A 15–20 litre fabric pot works well. Use a light, airy growing medium with good drainage.
- Run your lights on an 18/6 or 20/4 schedule from start to finish. No need to switch to 12/12 — she's an autoflower, so she'll begin flowering on her own around week 3–4.
- Feed lightly during the seedling stage. Once she enters vegetative growth, increase nutrients gradually. She's mostly indica, so she handles nitrogen well in veg but watch for overfeeding — yellowing leaf tips are your warning sign.
- As buds develop (typically from day 25–30 onwards), switch to bloom nutrients. Her buds get dense and heavy with resin, so ensure good airflow around the canopy to prevent moisture buildup.
- Ventilation is non-negotiable indoors. Those large, resin-covered buds produce a seriously pungent aroma. Without a carbon filter, your entire flat will know what you're up to. This isn't a subtle plant.
- Harvest around day 65–70. Check trichomes with a loupe — you're looking for mostly milky with a few amber heads for peak maturity. The buds will be dense, sticky, and absolutely caked in resin.
Aroma and Bud Structure
We've handled a lot of seeds over the years, and the genetics behind Auto Critical HOG consistently produce some of the stickiest, most resin-drenched buds you'll see from an autoflower. The aroma is heavy and earthy with a sharp, almost fuel-like edge — that's the Tennessee HOG shining through. It's the kind of smell that clings to your fingers after trimming. If you're growing indoors without carbon filtration, your neighbours three doors down will have opinions.
The buds themselves are dense and compact, typical of a heavy indica. They stack tightly along the main cola and side branches, and the resin coverage extends right down to the sugar leaves. For anyone interested in making extracts or concentrates, this is a strain that gives you plenty of material to work with. The trichome density is genuinely above average for an auto.
Auto Critical HOG vs Other Beginner Autoflowers
If you're weighing up your options, here's how Auto Critical HOG stacks up against two other popular beginner autos. The trade-off is always speed versus yield — and Auto Critical HOG lands firmly on the yield side of that equation.
| Trait | Auto Critical HOG | Typical Fast Auto | Typical Low-Rider Auto |
|---|---|---|---|
| Seed to Harvest | 65–70 days | 55–60 days | 50–55 days |
| Indoor Yield | 350–550 g/m² | 200–325 g/m² | 150–250 g/m² |
| Indoor Height | Up to 100 cm | 60–80 cm | 40–60 cm |
| Difficulty | Beginner | Beginner | Beginner |
| Dominance | Mostly Indica | Varies | Indica |
| Aroma Intensity | Very Strong | Moderate | Low–Moderate |
The takeaway: if you've got the vertical space (100 cm minimum indoors) and proper ventilation, Auto Critical HOG will out-produce most beginner autos by a significant margin. If you're working with a tiny stealth setup under 60 cm, she's probably too big — look at a compact auto instead.
Honest Limitations
No strain is flawless, and we'd rather you know what to expect before you plant. Auto Critical HOG's main drawback is her flowering time. At 65–70 days, she's on the slower side for an autoflower. If you're after the quickest possible turnaround, this isn't your strain. She also gets big — 100 cm indoors is a lot of plant for a small tent, and her lateral spread means she'll crowd out neighbours if you pack too many into a tight space.
The aroma is another consideration. It's a positive if you love dank, resinous genetics. It's a problem if you need discretion. We've seen growers underestimate this — Auto Critical HOG in full flower smells like a coffee shop on a warm afternoon. Carbon filtration isn't a suggestion; it's a requirement for indoor grows.
That said, these are trade-offs, not deal-breakers. The yield-to-effort ratio on this strain is outstanding. You put in beginner-level work and get experienced-grower results. That's the whole point of her.
Frequently Asked Questions
How long does Auto Critical HOG take from seed to harvest?
65–70 days on average. She's not the fastest auto around, but the extra time translates directly into heavier yields — 350–550 g/m² indoors. Worth the wait.
What yield can I expect from Auto Critical HOG indoors?
Between 350 and 550 g/m², depending on your setup and growing conditions. That's well above average for an autoflowering strain. Good lighting and proper ventilation push you toward the higher end of that range.
Is Auto Critical HOG suitable for beginner growers?
Yes — she's one of the best beginner autos we'd recommend. She's resilient, forgiving of minor mistakes, and doesn't need a light schedule change. Just make sure you have enough vertical space (at least 100 cm indoors) and decent ventilation.
Does Auto Critical HOG smell a lot during flowering?
Very much so. Her large, resin-coated buds produce a strong, pungent aroma that fills a room fast. Indoor growers absolutely need a carbon filter and extraction fan. Without one, discretion goes out the window — literally.
What's the difference between the 3-seed and 5-seed pack?
Same genetics, different quantities. The 3-pack (CSTS0090) suits a test run or a single-tent grow. The 5-pack (CSTS0018) gives you a full canopy or spare seeds for a second cycle. All seeds are feminized autoflowers.
How tall does Auto Critical HOG grow?
Up to 100 cm indoors and around 120 cm outdoors under favourable conditions. She's a stocky, expansive plant — not a tall, stretchy sativa. Plan for lateral spread as well as height.
Do I need to change the light cycle for Auto Critical HOG?
No. As an autoflowering strain, she flowers based on age rather than light cycle. Most growers run 18/6 or 20/4 from germination through harvest. No need to switch to 12/12.
