No more worrying about late frosts or weak harvests. Outdoors, it powers through autumn weather and still delivers.

Step-by-step growing guide

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C (71.6–77 °F)
2. Transplant to a 3–7 L pot once roots emerge (approx. 3–5 days)
3. Switch to 12/12 light cycle to trigger flowering after 2–3 weeks of veg
4. Use a well-draining soil or coco mix with good aeration
5. Apply organic bloom boosters like Bio Bloombastic during mid-flowering for denser buds
6. Monitor trichomes: harvest when mostly milky with some amber for full body effect
7. Flush with plain water 7–10 days before harvest to improve taste and smoothness

Frequently Asked Questions

Is Mayday Express suitable for beginners?

Yes, its resilience and forgiving nature make it ideal for novice growers. Just avoid overwatering and respect light cycles.

Can I grow Mayday Express outdoors in a cold climate?

Absolutely. Its mold resistance and early finish help it thrive even in cooler, wetter regions. Harvest before the worst of autumn hits.

Does this strain need a lot of nutrients?

It’s a moderate feeder. Stick to balanced veg nutrients and ramp up PK during flowering. Overfeeding can reduce terpene production.

How can I maximize yield indoors?

Use LST or SCROG to expose more bud sites to light. Pair with Piranha early in flowering to boost root mass and nutrient uptake.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of fast strains, but Mayday Express stands out. I ran it in a 1.2 x 1.2 m tent with 6 plants in 11 L pots. I used LST early and switched to 12/12 after three weeks. At week seven, the smell was insane — diesel with a hint of citrus. I fed it Sensi Grow A+B in veg and switched to bloom formulas with PK boosters.

Harvest came at day 56. I got 612 g/m² — one of my best indoor runs ever. The buds were rock-hard, covered in trichomes, and burned smooth. The high hits fast: relaxing but not couch-locking. Perfect for unwinding after work. If you want speed, yield, and quality in one package, this is your strain.
