G14 Auto Cannabis Seeds by FastBuds
G14 Auto is an autoflowering, mostly Indica cannabis seed that delivers up to 550g/m² in just 8–9 weeks from germination. FastBuds created this hybrid by crossing G13 Hash Plant with two different Lowryder strains, producing a compact, stable plant that stays between 40 and 80cm tall — short enough for a small tent, productive enough for a serious harvest. With 18% THC and 0.9% CBD, G14 Auto packs genuine potency into a frame that barely reaches your waist.
Why G14 Auto Seeds Deserve a Spot in Your Grow Room
G14 Auto solves a specific problem: you want Indica-dominant potency and proper yields, but you don't have the ceiling height, the patience for photoperiod schedules, or the experience to nurse a fussy strain through its lifecycle. This is the seed you plant when you want results without drama.
The G13 Hash Plant genetics bring the resin production and that heavy, full-bodied Indica character. The two Lowryder parents contribute the autoflowering trait and the compact structure. The combination is remarkably stable — we've seen growers run multiple plants from the same pack and get consistent phenotypes, which isn't always a given with autos. That consistency matters if you're filling a tent and want an even canopy without having to train out one lanky outlier.
The honest limitation? At 40–80cm, you're not going to get the towering colas you'd see on a photoperiod giant. But what you lose in height, you gain in speed and simplicity. No light schedule changes, no sexing, no waiting 12+ weeks for flower. You germinate, you water, you feed, and 8–9 weeks later you're trimming. For a first-time grower or someone running a quick rotation, that's hard to beat.
G14 Auto Yield and Growing Specs
G14 Auto produces between 400 and 550g/m² indoors under proper lighting — that's genuinely impressive for an autoflower that finishes in under 10 weeks. Outdoors, expect 70 to 250 grams per plant depending on your climate and how much sun the plant gets.

The 18% THC puts G14 Auto solidly in the mid-to-high range for autoflowers. The 0.9% CBD is notable too — not enough to call this a CBD strain by any stretch, but enough to add a subtle layer to the overall cannabinoid profile. Traditionally, strains with this kind of THC-to-CBD ratio have been used for relaxation and physical comfort. According to Benowitz and Jones (1975), prolonged THC ingestion produces measurable cardiovascular effects, which is worth being aware of if you're growing for personal use and tend to consume heavily.
G14 Auto Compared to Other FastBuds Autoflowers
If you're weighing G14 Auto against other autos in the FastBuds lineup, the main differentiator is the combination of compact size and high yield. Many autos that stay under 80cm will give you 200–350g/m² at best. G14 Auto pushes past 400g/m² regularly, which puts it closer to what you'd expect from a photoperiod in terms of productivity.
| Feature | G14 Auto | Typical FastBuds Auto |
|---|---|---|
| Height | 40–80 cm | 60–120 cm |
| Indoor Yield | 400–550 g/m² | 350–500 g/m² |
| Seed to Harvest | 8–9 weeks | 8–11 weeks |
| THC | 18% | 15–25% |
| Dominant Type | Mostly Indica | Varies |
Where G14 Auto really shines is in small tents — a 60x60cm or 80x80cm setup. The short stature means you can keep your light closer without burning the tops, and you won't need to do aggressive LST or topping to manage height. We'd pick G14 Auto over taller autos every time if vertical space is limited. If you've got a 120cm tent with proper headroom, you might look at something with more stretch for bigger individual colas — but for efficiency per square metre in a compact space, G14 Auto is the best auto for small grow tents in this price range.
How to Grow G14 Auto Seeds
- Germinate your G14 Auto seeds using the paper towel method or by placing them directly into a small pot of moist, light soil mix. Taproots typically appear within 24–72 hours. Plant the germinated seed about 1cm deep, taproot facing down.
- Use a final container from the start — 7 to 11 litres works well for autos. Transplanting stresses autoflowers and can stunt growth, costing you yield. Fabric pots promote better root aeration for these compact plants.
- Run your lights on an 18/6 or 20/4 schedule from start to finish. G14 Auto doesn't need a light cycle change to flower — she'll start on her own around week 3–4. A 250W to 400W LED is plenty for a small tent with 2–4 plants.
- Feed lightly during the first 2 weeks — seedling-strength nutrients only. Increase to vegetative feeding in weeks 2–4, then switch to bloom nutrients once you see the first pistils. Autos are sensitive to overfeeding, so err on the side of less.
- Keep humidity around 60–70% during veg, dropping to 40–50% during flower to prevent mould. The dense Indica buds on G14 Auto can trap moisture, so good airflow is critical — a small oscillating fan pointed at the canopy does the job.
- Harvest when 70–80% of trichomes are milky with some turning amber. Given the 8–9 week timeline, start checking trichomes around day 50. A jeweller's loupe or USB microscope is worth the small investment.
Complete your G14 Auto setup with a propagation kit for reliable germination and a compact grow tent if you're working with limited space. A jeweller's loupe is worth grabbing too — checking trichome ripeness is the difference between a good harvest and a great one. For feeding, a nutrient dosing syringe set keeps your measurements precise, which matters with autoflowers that don't tolerate overfeeding well.
Frequently Asked Questions
How long does G14 Auto take from seed to harvest?
8–9 weeks from germination to harvest. That's the full cycle — no separate veg and flower periods to manage. You'll typically see the first pistils around week 3–4, and the buds fatten up rapidly from week 5 onwards.
What yield can I expect from G14 Auto indoors?
400–550g/m² under proper indoor lighting. The higher end of that range requires good light coverage (LED or HPS), appropriate feeding, and the kind of airflow that keeps those dense Indica buds mould-free. Outdoors, expect 70–250g per plant.
Is G14 Auto good for beginners?
Yes — it's one of the more forgiving autos we stock. The compact 40–80cm height means you won't run into light-burn issues in a small tent, and the autoflowering trait removes the need to manage light schedules. Feed conservatively and you'll get solid results on your first run.
Does G14 Auto need a light schedule change to flower?
No. G14 Auto flowers automatically regardless of light cycle. Run 18/6 or 20/4 from germination to harvest. The Lowryder genetics handle the timing — no need to switch to 12/12.
How tall does G14 Auto grow?
Between 40 and 80cm. Most plants settle around 60cm in a standard indoor setup. This makes G14 Auto well suited to small tents, stealth grows, and balcony setups where height is a constraint.
What's the THC and CBD content of G14 Auto?
18% THC and 0.9% CBD. The THC level is solid for an autoflower — strong enough for experienced users, manageable for newcomers who dose carefully. The 0.9% CBD adds a subtle dimension to the cannabinoid profile without diluting potency.
Can I grow G14 Auto outdoors?
Absolutely. G14 Auto performs well outdoors in temperate and Mediterranean climates. Each plant yields 70–250g depending on sunlight exposure and growing conditions. The short stature keeps it discreet, and the 8–9 week cycle means you can run multiple rounds in a single season.
