About LA Ultra Auto

Can I grow LA Ultra outdoors in New Zealand? Absolutely. This 72/28 indica is well-suited to the New Zealand outdoor season running October through April. The compact growth habit means it will not tower above your fence line, and the dense flower structure packs serious weight into a manageable frame. Flowering takes 50-60 days, placing your harvest window squarely in March or April for most New Zealand latitudes.

What kind of yield should I realistically expect? Indoor growers pulling up to 250 g/m2 is achievable with decent LED lighting and attentive feeding. Outdoors, up to 200 g/plant per plant is realistic in 50+ litre pots or directly in prepared garden soil with full sun exposure. At 18% THC and a myrcene-forward terpene profile, the quality-to-effort ratio makes LA Ultra genuinely worthwhile.

Is this strain forgiving for newer growers? Reasonably so. A grower with basic knowledge of pH, feeding schedules, and light cycles will manage fine. It is not the most forgiving plant if you neglect it entirely, but it will not collapse at the first missed watering either.

More Questions New Zealand Growers Ask About LA Ultra

What growing medium works best for this strain? For maximum flavour complexity, organic soil blended with 30% perlite and enriched with slow-release amendments (blood and bone, rock phosphate, kelp meal โ€” all readily available at Bunnings or your local hydro shop). For maximum yield, coco coir with automated fertigation at EC 1.4-1.8 during bloom. Both approaches produce excellent results with this indica genetics.

How does it handle a humid New Zealand autumn? The dense foliage provides natural self-shading, which helps. Above 35ยฐC, growth slows noticeably but the plant does not collapse. Mulching the root zone and watering in the early morning (before 7am) prevents heat stress in most parts of the country.

When should I start feeding bloom nutrients? Within the first week of visible pistil formation. This cultivar's 72/28 genetics shifts its nutritional demand rapidly at the transition. Phosphorus and potassium uptake increases noticeably, whilst nitrogen demand drops. An organic top-dress of bat guano and sulphate of potash works well for soil growers; hydro and coco growers should switch to a bloom-ratio formula (low N, high PK) immediately.

Indoor or outdoor โ€” which is better for this strain? Both work. Indoor gives you control over the 50-60 days environment. Outdoor in the New Zealand growing season (October-April) lets the plant reach its full up to 200 g/plant potential with natural sunlight intensity that even expensive LEDs struggle to match. Flowering: 50-60 days. Indoor yield: up to 250 g/m2. Outdoor yield: up to 200 g/plant. Rated intermediate difficulty.

What to Expect When Using LA Ultra

New Zealand users report euphoric, calm as the defining characteristics, and our experience aligns with that consensus. At 18% THC, this indica sits in a potency bracket where dosage control genuinely matters. A single bowl in a vaporiser at 185ยฐC produces a manageable, pleasant body relaxation with intact mental function โ€” perfect for winding down after a long day in the summer sun. Increasing the dose shifts the experience firmly towards physical sedation, and many users find this their preferred nighttime cultivar during the cooler months. The Myrcene/Humulene terpene combination imparts a flavour that lingers on the palate โ€” earthy and slightly sweet with a fruit-like finish.

Ideal settings: quiet evenings, film nights, post-exercise recovery, and sleep preparation.

Terpene Breakdown

Primary: Myrcene ยท Secondary: Humulene ยท Tertiary: Linalool. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188ยฐC) highlights the humulene and linalool notes whilst keeping myrcene as a foundation. Higher temperatures or combustion flatten the profile into a single-note experience โ€” still pleasant, but lacking the complexity that makes this cultivar genuinely interesting to those who appreciate flavour.

Suitability and Recommendations

LA Ultra suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar โ€” it will not hold your hand, but it will not punish minor mistakes harshly either. Autoflowering genetics eliminate the need for light cycle manipulation, making this ideal for balcony growers, guerrilla setups, and anyone wanting a fast turnaround from seed to harvest. The New Zealand growing season (October through April) accommodates the 50-60 days bloom period comfortably for outdoor growers in the warmer northern regions. Shipped discreetly within New Zealand with sourced grow figures on every strain page.
