Mexican Rush Auto FAQ

Is Mexican Rush Auto sativa or indica?

Mexican Rush Auto is a predominantly sativa strain, with an 80% sativa, 15% indica, and 5% ruderalis genetic makeup.

Sativa strains are known for their uplifting, energizing effects, making them perfect for daytime use, creative tasks, and social gatherings.

They typically grow taller, develop thinner leaves, and take longer to flower compared to indicas.

Indicas, on the other hand, are more compact, produce dense buds, and deliver a relaxing, body-focused high.

With its strong sativa dominance, Mexican Rush Auto brings all the cerebral stimulation sativa lovers crave, while maintaining a manageable height and fast flowering time.

How long does Mexican Rush Auto take to grow?

From seed to harvest, Mexican Rush Auto takes around 14 weeks, making it a relatively fast-growing sativa.

The flowering stage lasts approximately 8–10 weeks, after which the plant is ready for harvest within 13–14 weeks from germination.

Compared to traditional sativas, which can take months to fully mature, this strain offers a much quicker turnaround.

How tall does Mexican Rush Auto grow?

Indoors, this strain typically reaches 80–130 cm (2.6–4.3 ft), making it suitable for controlled grow spaces.

Outdoors, with ample sunlight, it can stretch up to 150 cm (4.9 ft), growing taller than many autos but still manageable.

Its size is well-balanced, offering the benefits of a classic sativa without overwhelming your grow area.

Does Mexican Rush Auto need a special light cycle?

No, this strain is autoflowering, meaning it doesn’t rely on light cycles to trigger flowering.

Unlike photoperiod strains that need a shift to 12/12 light to bloom, Mexican Rush Auto will start flowering automatically, usually around weeks 4–5.

This makes it a great choice for growers who want a hassle-free cycle without adjusting light schedules.

Is Mexican Rush Auto resistant to pests and mold?

Yes, Mexican Rush Auto has high resistance to pests and mold, making it a reliable choice for growers in humid or unpredictable climates.

Its sturdy genetics help it withstand common cannabis plant issues, though proper airflow and humidity control are still recommended.

What climate is best for growing Mexican Rush Auto?

Mexican Rush Auto thrives in warm, sunny climates similar to the Mediterranean, but it can also perform well in slightly cooler environments due to its resilience.

Outdoor growers in temperate regions can still achieve solid results, especially in the peak summer months.

For indoor growers, maintaining stable temperatures between 20–26°C (68–79°F) will ensure optimal growth and resin production.
