Super Critical Autoflowering Seeds – Fast, Potent & High-Yielding Autoflowering Cannabis

Super Critical Autoflowering from Green House Seeds is the ultimate autoflowering workhorse, designed to deliver a massive, potent harvest with minimal fuss and maximum speed. This strain is your shortcut to heavyweight, resin-coated buds and a powerful, full-body stone.

Do you ever feel like you're waiting forever for your plants to finish, only to be disappointed by a modest yield? Many growers get stuck in a cycle of long flowering times and underwhelming results, wasting precious months and energy. Super Critical Autoflowering shatters that frustration by condensing the best traits of its legendary parents—Big Bud, Skunk, and White Widow—into a fast, automatic, and incredibly generous plant.

How to Use It for Maximum Results

Super Critical Autoflowering is incredibly versatile, but it truly shines when you play to its strengths. Its autoflowering nature means it transitions to bloom automatically based on age, not light schedule, making it perfect for a continuous harvest setup or for fitting multiple cycles into a single season outdoors.

For indoor growers, a Sea of Green (SoG) method is highly recommended. Its moderate height and tendency to produce a dominant central cola surrounded by solid side branches make it ideal for packing multiple plants under a single light to maximize your yield per square meter.

How to Grow Super Critical Autoflowering

Quick Overview: An autoflowering, indica-dominant hybrid from Green House Seeds with a fast 7–8 week cycle. Ideal for beginners and growers seeking high yields in minimal time, both indoors and in warm outdoor climates.

Safe Start: Germinate seeds in a warm (22–25°C / 71–77°F), humid environment. Plant directly into its final pot (11–20 L / 2.9–5.3 gal) to avoid stunting its automatic growth cycle. For a strong, stress-free start, consider a root stimulator like HESI Root Complex.

Veg & Early Growth: Provide 18–20 hours of light daily. Keep temperatures between 22–26°C (71–79°F) and humidity around 60–70%. Water lightly but consistently, allowing the substrate to dry slightly between waterings. Low-Stress Training (LST) can be applied early to encourage an even canopy and maximize light exposure to bud sites.

Flowering & Ripening: The plant will automatically begin flowering around weeks 3–4. Gradually lower humidity to 40–50% to prevent mold. Ensure good airflow around the dense buds. To support the heavy flower development and enhance resin production, a bloom booster like Canna Boost can be beneficial during peak flowering.

Harvest & Post-Harvest: Harvest when trichomes are mostly milky with some amber for a more relaxing effect. Flush with plain water for the last 7–10 days. Dry slowly in a dark space at 18–22°C (64–72°F) and 50–60% RH for 10–14 days, then cure in jars for at least 2–4 weeks to develop flavour and smoothness.

Frequently Asked Questions

Is Super Critical Auto good for beginners?

Absolutely. Its autoflowering nature removes the complexity of light schedule management, and its robust genetics make it forgiving of minor growing errors. It's an excellent choice for a first-time grow.

How tall does Super Critical Auto get?

It stays relatively compact, typically reaching 80–90 cm (31.50–35.43 in) outdoors. Indoors, its height is easily managed with pot size and light distance, making it suitable for tents of 1.20 m (3.94 ft) or more.

What's the best lighting schedule for autoflowers like this?

You can run autoflowers like Super Critical Auto under 18, 20, or even 24 hours of light per day. 18–20 hours is the sweet spot, maximizing growth without excessive electricity costs.

Can I top or heavily prune Super Critical Auto?

It's not recommended. Autoflowers have a fixed life cycle, and aggressive techniques like topping can cause significant stress that stunts growth and reduces final yield. Stick to Low-Stress Training (LST) for best results.

When is it ready to harvest outdoors?

Since it's autoflowering, it's ready based on age, not the season. Plant it anytime after the last frost when temperatures are consistently above 10°C (50°F), and it will be ready in roughly 8 weeks, regardless of day length.

Personal Experience of Pevgrow’s CEO (Alan)

I've run Super Critical Auto in my personal garden a few times, and it's become a go-to for when I need a reliable, heavy-yielding strain without the wait. I love popping a few of these in a spare corner of the tent under a 600W HPS. They don't stretch too much, so they're perfect for filling in lower canopy spaces or running a quick Sea of Green. The yield is honestly impressive for an auto; the buds stack weight quickly and get absolutely caked in trichomes by the end.

My favourite way to grow it is in a 15 L (4 gal) fabric pot with a light, airy soil mix. I'll gently bend the main stem over when it's about 20 cm (7.87 in) tall and tie down the branches as they grow. This opens up the plant and gets light to all those potential bud sites. I keep the feed simple—a balanced vegetative formula early on, then switch to a PK-heavy bloom booster around week 4. The plant tells you when it's hungry; the leaves will lighten up a touch.

The smoke is exactly as advertised: a proper, heavy indica stone. It's my weekend evening strain when I want to just melt into the couch. The flavour is old-school—earthy, skunky, with a sweet finish. It's not the most exotic terpene profile on the market, but it's classic, potent, and effective. If you're looking for an auto that acts like a photoperiod in terms of yield but gives you the speed and simplicity of an auto, this is a fantastic choice.
