About Maui Haole Feminised

Germination and early veg, days 1-14. Maui Haole seeds generally crack inside 48 hours on damp kitchen roll and break the surface around day three. Early growth came in even and unhurried, neither racing nor sulking. Four solid nodes by day 14 with the spacing that hints at the hybrid frame to come. Damping off is rare around 70% relative humidity, which is also roughly what an unheated British room sits at in spring.

Veg, weeks 3-6. It took a simple top-and-tie approach well. Topping at node four gave six strong leaders, tied down gently, and an even canopy across a 70cm square by the flip.

Bloom, weeks 1-9. This is where the 55/45 balance in Maui Haole showed itself. The myrcene came up in week three and kept building; trichome cover was obvious to the naked eye from week five. Indoor yield: 275–475 g/m². THC testing at 15%. Rated intermediate.

The rest of the diary

Mid-bloom, weeks 4-6. The change came quickly. Sites that were loose and wispy at week three closed into defined colas. Development stayed even across the whole canopy, which is what the veg training bought — eight comparable colas instead of one dominant top and a handful of also-rans. Resin was visible to the naked eye from week four.

Ripening, weeks 7-9. Feeding dropped to plain water for the last ten days. The myrcene got strong enough that carbon filtration stopped being optional in a terraced house. Trichomes ran clear to milky across the final fortnight, amber showing on sugar leaves first. Around 15% amber on the calyxes is a common place to stop.

Drying and curing. Whole plant hung in the dark at 17°C and 58% humidity for twelve days — both numbers held by a dehumidifier, because an October room in this country will not hold either on its own. Stems snapped rather than bent, which is the test worth trusting. Four weeks in glass followed, burped twice daily for the first fortnight and once daily after. Final weight matched the 275–475 g/m² figure. The limonene was far more present after the cure than at harvest, which is the argument for curing properly: the process makes flavour rather than merely keeping it.

Flowering: 60 days. Indoor yield: 275–475 g/m². Outdoor yield: 400–600 g/plant. Rated intermediate difficulty. Feminised seeds.

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. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the limonene and pinene audible over the myrcene base. Run it hotter, or burn it, and the three collapse into one note — pleasant enough, but none of the complexity that made it worth choosing.

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. Photoperiod genetics leave plant size and harvest date under your control — veg longer for bigger plants, or flip early when space is short. The April to October season accommodates a bloom of 60 days comfortably for outdoor growers across the country.
