Mexican Rush Auto by Royal Queen Seeds – Fast 14-Week Sativa Auto with Citrus & Pine Aromas

Mexican Rush Auto by Royal Queen Seeds is your passport to a true Mexican landrace sativa — now in a compact, 14-week autoflower that delivers euphoric highs, zesty citrus-pine aromas, and up to 500 g/m² without the hassle of photoperiods.

Are you stuck between loving sativas and hating their size and wait time?

You crave that creative, uplifting buzz only a real sativa can give. But let’s be real: most sativas grow like redwoods, need months to finish, and demand perfect conditions. You don’t have space for a jungle or time for a 5-month grow.

Wasting weeks on slow, space-hungry plants that barely deliver?

Every day your plants stretch instead of flower, you’re losing light cycles, electricity, and patience. Big sativas mean bigger risks — mold, instability, and attention you don’t want. And if they don’t deliver dense, flavorful buds? That’s money, time, and energy down the drain. You didn’t sign up for mediocre harvests and constant stress.

Mexican Rush Auto: the compact sativa that actually delivers in 14 weeks

Meet the solution: Mexican Rush Auto. Born from a legendary Mexican landrace and Royal Haze Auto, this 80% sativa packs all the authentic flavor and cerebral punch you love — in a plant that stays under 1.50 m (4.92 ft) and finishes fast. No more waiting, no more space drama. Just pure, clean sativa energy, ready when you are.

With Mexican Rush Auto, you get the full sativa experience — without the grow room overhaul.

Step-by-step growing guide

1. Germinate seeds in a moist paper towel or directly in a starter cube at 22–25 °C and high humidity.
2. Transplant to final pot (18–27 L) once roots emerge — avoid re-potting autos.
3. Use a light, airy soil mix or Plagron Premium Coco for better drainage and root health.
4. Maintain 18–20 hours of light daily, temperatures of 22–26 °C in veg and 20–25 °C in flower, and RH 50–60% early, dropping to 40–50% in late flowering.
5. Apply gentle LST early to shape the plant and improve light penetration — never top or FIM.
6. Harvest when most trichomes are milky with some amber for a balanced high — usually around week 14.

What’s the best setup for indoor growing?

Use a 250W LED or HPS in a 60x60x160 cm tent with 18–20 h light. Pair it with FloraDuo Grow for strong early development.

Can I grow it outdoors in a cold climate?

Yes, it handles short summers well. Start in late spring and harvest by early autumn.

Does it smell strong during flowering?

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of sativas, but Mexican Rush Auto stands out. I ran it in a small 80x80x160 cm tent with a 300W LED, 18/6 light, and Plagron soil. No topping — just light LST in week 3. It stretched about 30 cm in pre-flower, then packed on bud fast. By week 12, the trichomes were milky, and the citrus-pine smell was unmistakable. I harvested at week 14: 480 g/m² of frosty, energetic bud. The high is clean, uplifting, and lasts — perfect for daytime. Compared to other autos, this one tastes like real cannabis, not candy. My only tip? Don’t overfeed. Let the genetics shine.
