Seed germinated great, taking well to LST and defoliation. Will post updates when buds form.

Just harvested my Red Devil autos. I grew them outdoors, and they stayed relatively short, which was perfect for my garden space. The flowers are beautiful, with a nice layer of frost. The flavor is amazing, sweet with a hint of spice. The high is relaxing but keeps me functional, which I love. It’s also been a great strain for making edibles.

FAQ Red Devil Auto seeds

Frequently asked questions

What does Red Devil Auto taste and smell like?

Sweet and fruity with spicy, earthy pine notes. The aroma can be fairly pungent, combining sweet and herbal tones.

How long does Red Devil Auto take from seed to harvest?

Typically 8–10 weeks from seed to harvest, depending on environment and phenotype.

Is Red Devil Auto easy to grow for beginners?

Yes—it's a robust autoflower that tolerates minor mistakes and requires minimal maintenance.

Can I grow Red Devil Auto outdoors and what climate does it prefer?

Yes. It performs well indoors and outdoors, preferring mild to warm climates and doing best when daytime temperatures stay above 21 °C. Its fast cycle allows multiple runs per season in warm regions.

What light schedule works best for Red Devil Auto indoors?

An 18/6 or 20/4 light schedule from seed to harvest works great; 24/0 is possible but not necessary.

How tall does Red Devil Auto get?

Compact to medium height with moderate stretch in early bloom—well-suited to small spaces and discreet outdoor spots.

What yield can I expect from Red Devil Auto?

Moderate to high yields for an autoflower. Indoors, SCROG/SOG and strong lighting help maximize production; outdoors, results depend on sun hours and pot size.

What are the effects of Red Devil Auto?

Balanced hybrid effects: uplifting euphoria with a relaxing body feel. Suitable for late afternoon or evening; some users report relief from stress and mild aches.

Can I train or prune Red Devil Auto?

Gentle LST and light defoliation are fine. Avoid topping or heavy stress after week 3–4 because autos have a short veg phase.

Are Red Devil Auto seeds feminised?

They are autoflowering and typically sold as feminised seeds; check the product listing for exact options.
