Hawaiian Haze

Hawaiian Haze or Sativa is a strain that typically contains THC levels between 15% – 26% (Standard) / <1% (Hemp variety) and CBD levels ranging from <2% (Standard) / 15% – 21% (Hemp variety). Known for its Tropical, Pineapple, Citrus, Floral profile, this strain has a growth expectation of being Tall (Often exceeds 150cm–200cm if not trained) in height, with a nutrient demand that is Moderate (Heavy Nitrogen in Veg; watch for Sativa sensitivity).

This Sativa is of the Genetype: ~80% Sativa / 20% Indica. The Hawaiian Haze strain has 3 phases of the growing cycle.

The first phase is the Seedling Phase. Once you have decided to grow Hawaiian Haze in either soil or hydroponiclay, the ph levels need to be monitored. The ph level desired by Sativa is 6.0 – 6.8 and 5.5 – 6.0 hydroponically. During this infancy stage, Hawaiian Haze needs to maintain a target temperature of 70–85°F (21–29°C) for 2 to 3 weeks. Once the seed germinates, it will sprout it's first set of round leaves, or the cotyledons. If you are able to maintain the target humidity of 50% – 70%, the iconic serrated leaves will just begin to show themselves. During this critical Phase 1 of the Sativa growing cycle the plant is establishing a strong root sytem. Beginners often over water these fragile seedlings. Do not drown your seeds. You seedling Hawaiian Haze needs care and gentle light. The recommended light cycle for growing Hawaiian Haze is 18/6 (Standard) for the first cycle, which should last .

The next is the Vegetative Phase. The Hawaiian Haze will focus entirely on size and structural integity. The temperature needs also change for phase 2. If a target temperature of 65–80°F (18–26°C) is maintained and a target humidity of 40% – 50% is achieved, the Sativa will grow stems, branches and plenty of large fan leaves. This ~80% Sativa / 20% Indica is trying to build it's own solar panel of leaves to absorb energy. It is critical to maintain a proper light cycle of 12/12 for the entire phase 2 schedule. This consistent energy will help plant grow bigger without producing flowers, focusing it's energy on growing tall and strong. Hawaiian Haze is at it's most resilient and may grow quickly. As phase 2 comes to an end, it may be topped or tied down, as it's training suitability is considered High (Highly recommended: SCROG, Topping, LST to manage height).

The most exciting phase, when growing ~80% Sativa / 20% Indica is the Flowering Phase. The plants adulthood lasts . It is at this phase that the light cycle changes for the last time. Hawaiian Haze will produce the most flowers when the light cycle is 12/12 (Some growers drop to 11/13 for Sativas). Keep the temperature and humity controlled at 64–75°F (18–24°C) and 30% – 40% (Crucial for preventing mold in dense colas) so you can really watch this plant strecth and almost double in height. It will want to start producing early into the flowering process.

You will know the Hawaiian Haze is ready when the white hairs (pistils) turn amber/brown and the resin glands (trichomes) look milky or cloudy, rather than clear. Cutting the plant down even a week too early can significantly reduce the potency and weight of your harvest. Patience in the flowering phase will provide the best possible outomce of Sativa with a desired gorwth profile that will be:
Stretchy, vigorous, long internodal spacing, airy but resinous buds.

Growers Notes: Hobby Grower’s Field Guide
The Sativa Stretch: Be prepared for this plant to double or even triple in size once you flip the light cycle to 12/12. If you are growing in a tent with limited vertical space, topping and LST (Low Stress Training) are mandatory.

The Wait: Unlike quick Indica hybrids, Hawaiian Haze can take up to 14 weeks to fully mature. Don't harvest early—the terpene profile and resin production really peak in the final 10 days.

Airflow is Key: Because of its tropical lineage, it prefers warm weather, but its dense Haze-style flowers can be magnets for Botrytis (Bud Rot) if your humidity isn't strictly controlled in Phase 3.

Nutrient Sensitivity: Sativas can sometimes be "finicky" with high-strength synthetic nutrients. Start with 50% of the recommended dose and watch for leaf tip burn.
