Lava Cake Auto
Lava Cake Auto is the Cannarado Genetics autoflower conversion of the bank's indica-dominant Lava Cake photoperiod line, crossing the original Thin Mint GSC x Grape Pie selection with ruderalis to lock the photoperiod-independent flowering trait into the rich chocolate-mint terpene profile that defined the photoperiod version. The total cycle runs ten to twelve weeks from seed under 18-to-20-hour light, with plants staying compact at 60 to 100 centimeters indoors and producing dense, dark-purple bud expression under cool nighttime temperatures in the final two weeks. The flavor carries the namesake chocolate-cake and mint terpene profile clearly through the auto conversion, with grape and berry undertones contributed by the Grape Pie parent, and the high leans indica-dominant with relaxed body effects and a clear euphoric component. Cannarado has been one of the more reliable banks at preserving original photoperiod terpene profiles in autoflower conversions, and Lava Cake Auto is one of the better dessert-leaning autos in the modern catalogue. The strain suits small grow spaces and growers wanting the Lava Cake profile in a shorter total cycle.

Terpene profile
The aromatic compounds below shape how Lava Cake Auto smells, tastes, and ultimately feels in the body.
- dominant
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- secondary
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- secondary
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- minor
Linalool
Floral and lavender-like — calming, often noted for sleep and anxiety support.

Lineage
Lava Cake Auto traces to Lava Cake × ruderalis. The cross sits in the Cookies x Grape Pie x ruderalis family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Lava Cake Auto
These EC and NPK targets are starting points calibrated for the strain's Hybrid lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.0-1.2 EC
- Early flower
- 1.1-1.3 EC, NPK 2-2-4
- Mid flower
- 1.4-1.6 EC, NPK 1-3-5
- Late flower
- 1.2-1.4 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
Lava Cake Auto is documented with a 11-week flower split across the standard hybrid phases. The visual below maps a documented 15-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Lava Cake Auto concentrate the most observational notes on the mid-to-late flower transition. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Lava Cake Auto. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-8)
- Lava Cake Auto is documented as having low stretch. Reports describe the plant roughly doubling in height during this phase as the hybrid structure establishes its final flowering frame.
- Bud sites (weeks 9-10)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Lava Cake Autonote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 11-13)
- Flowers thicken and calyxes fatten through this phase. Documented Lava Cake Auto runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 14)
- Trichomes transition from clear toward cloudy and amber. Reports for Lava Cake Auto describe the Caryophyllene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 15)
- Calyx swelling is documented as complete and the harvest window opens. Published Lava Cake Auto runs end here, within the 10-12 week flowering range reported by the breeder.

Common questions about Lava Cake Auto
Does Lava Cake Auto turn purple?
Yes, under cool nighttime temperatures in the final two weeks of flowering. The Grape Pie genetics carry strong anthocyanin expression through the auto conversion, and growers who drop tent temperatures into the 60-to-65-degree Fahrenheit range in late flowering will see deep purple bud coloration.
How does the auto compare to photoperiod Lava Cake?
Cycle time is shorter at ten to twelve weeks from seed versus a full vegetative period plus eight to nine weeks of flowering. Per-plant yields are lower but the chocolate-mint terpene profile carries through the auto conversion better than most dessert-family autoflower lines.
