Grow Smarter: Tips for a Seamless Experience

Keep your plants in a stable environment — 22–26 °C (71.6–78.8 °F) during growth, 20–25 °C (68–77 °F) in flowering. Use BN-Roots early to boost root development and resilience. For a cleaner finish, flush with Canna Flush 7–10 days before harvest.

How to Grow Auto Sweet Critical for Best Results

Quick overview: autoflowering · 00 Seeds · 65–70 day cycle · low difficulty · ideal for small spaces and Mediterranean climates.

Solid start: Germinate in a warm, moist environment — 22–25 °C (71.6–77 °F) with high humidity.

• Use jiffy pellets or starter cubes for clean germination
• Transplant carefully when root tip is ~1 cm (0.4 in) long
• Avoid deep planting — keep cotyledons near surface
• Place in final 18–27 L (4.76–7.14 gal) pot from the start
• Use Humushemp for organic, airy soil structure

Stable seedling: Protect young plants from stress and overwatering.

• Provide 18–20 hours of light daily with low-intensity LEDs
• Water lightly — let topsoil dry between irrigations
• Add BN-Roots to boost root mass and nutrient uptake
• Keep temps stable — avoid cold drafts or heat spikes
• Begin mild nutrients after first true leaves appear

Directed growth: Support natural vigor without aggressive pruning.

• Switch to flowering nutrients after 3 weeks
• Use LST to open canopy and improve light penetration
• Avoid topping — autos can’t recover from stress
• Ensure good airflow to prevent humidity buildup
• Monitor pH and EC — keep levels stable

Flowering care: Maximize bud density and resin in the final stretch.

• Reduce humidity to 40–50% to prevent mold
• Support heavy colas with soft plant ties

Frequently Asked Questions

How long does Auto Sweet Critical take to grow?

From seed to harvest, it takes 65–70 days. No light cycle changes needed — just 18–20 hours of light per day from start to finish.

Is this strain good for beginners?

Absolutely. It’s low-maintenance, resistant to pests and mold, and doesn’t require advanced techniques. Just keep the basics right and you’ll succeed.

Can I grow it outdoors in colder climates?

Yes, but aim for a warm, sunny spot. It thrives in Mediterranean climates but can handle mild temperature drops thanks to its ruderalis genetics.

Does it smell strong during flowering?

It has a medium odor — sweet and fruity, but noticeable. If discretion is key, use a carbon filter or grow in a secluded area.

What’s the best way to increase yield?

Use LST early, provide strong light, and feed with bloom boosters like Super PK. Avoid over-pruning — autos don’t recover well from stress.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Auto Sweet Critical three times now — once outdoors in Murcia, twice in my 1.20 x 1.20 m tent. What I love most is how predictable it is. Every plant stays under 1 meter, grows like a bush, and finishes right on time. I used 20L pots, full-spectrum LEDs, and a simple soil mix with Humushemp. I applied BN-Roots at transplant and Super PK in week 5. The buds were dense, sticky, and smelled like ripe mango. I flushed for 10 days and cured for 3 weeks — the smoke was smooth, flavorful, and perfectly balanced. If you want a no-drama autoflower that delivers every time, this is it.
