Are You Tired of Waiting Months Just to Harvest?

Most cannabis strains keep you waiting 14, 16 weeks or more before you can even think about trimming. That’s a long time to stay patient — especially if you're growing in a small space or need discretion.

And when you finally harvest, what if the plant didn’t perform? What if it got mold, stretched too much, or barely produced anything? All that time, effort, and energy — wasted. You start questioning whether growing is even worth it.

With Wedding Cake Auto, you skip the long wait and the stress. This strain goes from seed to harvest in just 10 weeks, with minimal care, high yields, and a forgiving nature that makes it perfect for both new and experienced growers.

Fast-Track Growing Cycle

Forget complicated light schedules. Wedding Cake Auto thrives under 18–20 hours of daily light, from seed to harvest. No switching to 12/12 needed — just plant, feed, and watch it grow.

• Germinate seeds in a moist paper towel or Root It 150ml – Rooting gel for faster, stronger starts
• Transplant once the taproot is about 1 cm (0.4 in) long

• Keep humidity at 60–70% in the first week, then drop to 50–60%
• Maintain pH between 6.0–6.5 in soil or 5.8–6.2 in coco

• Avoid overfeeding — autos are sensitive to nutrients

Flowering by stages

Watch the trichomes, not the calendar.

• Weeks 1–2: Pre-flower stretch — support weak branches
• Weeks 3–4: Bud sites form — increase potassium and phosphorus
• Weeks 5–6: Rapid bud growth — maintain airflow and RH 40–50%
• Weeks 7–8: Trichomes turn milky — start monitoring for harvest
• Use P-Boost flowering stimulator additive with phosphorus | Aptus to boost resin and density

Harvest, drying and curing

Timing is everything.

• Harvest when 70% trichomes are milky, 30% amber for balanced effect
• Flush 7–10 days before harvest to improve taste
• Dry at 18–22 °C and 50–60% RH for 7–10 days
• Cure in jars for 2–4 weeks, burping daily

Typical mistakes and how to avoid them

• Overwatering: Let soil dry slightly between waterings
• Overfeeding: Start with half-strength nutrients and increase slowly

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Wedding Cake Auto stands out. I ran it in my 1.20 m x 1.20 m (4 x 4 ft) tent under a 600W LED, with 5 plants in 20L pots. I used organic soil with added perlite and mycorrhizae. I didn’t top them — just gentle LST to open up the canopy. By week 6, the buds were already dense and frosty. I added P-Boost in week 4 of flowering, and it made a visible difference in resin production. I flushed for 10 days, dried slowly, and cured for 3 weeks. The high was smooth, uplifting, and lasted for hours. I’d grow it again in a heartbeat — especially for quick, reliable harvests.
