About Maui Haole Auto

Read Maui Haole backwards from the harvest: up to 300 g/m2 under lights, up to 350 g/plant outdoors, with resin filling out towards 15% THC. Weight goes on evenly across the 55-65 days of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 55/45 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the myrcene arrive.

Getting the weight out of this plant

Three stretches of the 55-65 days of bloom decide whether you reach the top of this strain's range (up to 300 g/m2 indoors, up to 350 g/plant outdoors). The rest is maintenance.

The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Myrcene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.

The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 55-65 days. Indoor yield: up to 300 g/m2. Outdoor yield: up to 350 g/plant. Rated intermediate difficulty.

What Maui Haole is actually like

Growers report relaxed, happy, euphoric as the defining characteristics and our own notes agree. At 15% THC this hybrid sits where the balance is the selling point. Taken small it stays functional; taken larger it relaxes properly. The ${indica}/${sativa} split means the direction is set by how much you take rather than fixed by the genetics. The Myrcene/Limonene pairing leaves earth and faint sweetness on the palate, with fruit at the end.

Best suited to most occasions — the dose does the steering.

Terpene breakdown

Primary: Myrcene · Secondary: Limonene · Tertiary: Pinene. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with myrcene; after three or four weeks sealed in glass at 16-18°C the pinene underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter pinene molecules are the first thing heat destroys.

Who it suits

Maui Haole suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Autoflowering genetics take the light cycle out of the equation, which suits balcony growers, anyone working around British daylight hours, and anyone who wants the whole thing over quickly. The April to October season accommodates a bloom of 55-65 days comfortably for outdoor growers across the country.

Maui Haole Auto — Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.

Stabilisation Level

Generations
5+
Breeding Programme
Autoflower Programme — five-generation auto trait fixing
Stabilisation Notes — What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Maui Haole sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Stabilise the recessive ruderalis trait in Maui Haole for uniform auto-trigger.

Selection Focus

Chosen for trichome density, bud structure and the hybrid trait balance the cross was engineered for.

Pollen / Mother Source

Royal King Genetics in-house breeder room — pollen taken from a generation-tracked sibling-male line.
