Whitethorn Rose

Whitethorn Rose or Sativa-dominant Hybrid (approx. 70% Sativa / 30% Indica) is a strain that typically contains THC levels between 18% – 25% and CBD levels ranging from < 1% (usually around 0.1% – 0.2%). Known for its Blood Orange, Rose, Sweet Berry, and Creamy Lavender profile, this strain has a growth expectation of being Medium to Tall; vigorous growth with long, "spiral-staircase" colas in height, with a nutrient demand that is Moderate to High; rewards a clean, organic regimen to preserve terpenes.

This Sativa-dominant Hybrid (approx. 70% Sativa / 30% Indica) is of the Genetype: Photoperiod (Clone-only originally; now available in specific seed crosses). The Whitethorn Rose strain has 3 phases of the growing cycle.

The first phase is the Seedling Phase. Once you have decided to grow Whitethorn Rose in either soil or hydroponiclay, the ph levels need to be monitored. The ph level desired by Sativa-dominant Hybrid (approx. 70% Sativa / 30% Indica) is 6.0 – 6.8 and 5.5 – 6.2 hydroponically. During this infancy stage, Whitethorn Rose needs to maintain a target temperature of 22°C – 28°C (72°F – 82°F) 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 60% – 70% RH, the iconic serrated leaves will just begin to show themselves. During this critical Phase 1 of the Sativa-dominant Hybrid (approx. 70% Sativa / 30% Indica) growing cycle the plant is establishing a strong root sytem. Beginners often over water these fragile seedlings. Do not drown your seeds. You seedling Whitethorn Rose needs care and gentle light. The recommended light cycle for growing Whitethorn Rose is 18/6 (Recommended 20/4 for clones to prevent premature bloom) for the first cycle, which should last .

The next is the Vegetative Phase. The Whitethorn Rose will focus entirely on size and structural integity. The temperature needs also change for phase 2. If a target temperature of 21°C – 26°C (70°F – 79°F) is maintained and a target humidity of 45% – 55% RH is achieved, the Sativa-dominant Hybrid (approx. 70% Sativa / 30% Indica) will grow stems, branches and plenty of large fan leaves. This Photoperiod (Clone-only originally; now available in specific seed crosses) 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. Whitethorn Rose 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; excellent for LST and Topping to manage the "Sativa stretch".

The most exciting phase, when growing Photoperiod (Clone-only originally; now available in specific seed crosses) is the Flowering Phase. The plants adulthood lasts . It is at this phase that the light cycle changes for the last time. Whitethorn Rose will produce the most flowers when the light cycle is 12/12. Keep the temperature and humity controlled at 18°C – 23°C (64°F – 73°F) and 35% – 45% RH 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 Whitethorn Rose 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-dominant Hybrid (approx. 70% Sativa / 30% Indica) with a desired gorwth profile that will be:
Vibrant purple hues, dense resin coating, and deep aromatic complexity

Growers Notes: Hobby Grower’s Notes
The "Early Finish" Trait: This strain is genetically predisposed to flower early. Indoor growers should keep a close eye on light cycles for clones; some growers use a 14/10 or even 13/11 transition to avoid shocking the plant into bloom too early.

Color Expression: The dramatic purple hues are a signature of Whitethorn Rose. To maximize this, ensure a 5°C – 10°C drop in temperature during the "lights off" period in Phase 3.

Hash Maker's Dream: If you are into concentrates, this is your strain. Its trichome structure is specifically celebrated for Ice Water Hash and Rosin production.

Root Bound Sensitivity: Avoid letting this strain become root-bound in small containers, as it can trigger premature flowering due to its sensitive "early finish" genetics.
