Flowering Type: Day length neutral plant will flower regardless of day length.

Flowering Mechanism: No vernalization required. Irradiance is the primary mechanism that initiates flowering. High light intensity will initiate flowering once plants reach 3-5 true leaves.

Germination: Maintain optimal conditions for seedling development, should begin on the day of sowing until root emergence. Expect root emergence in 3-6 days from sowing.

Cover: No cover.

Sowing method: 1 seed per plug.

Media: pH 5.6-5.8, EC 0.7-1.2.

Temperature: 20-22 °C (68-72 °F) until radicle emergence. Afterwards, ensure 18-20 °C (64-68 °F) during night and day. When the roots reach the bottom of the cell, the temperature can be lowered to 16-18 °C ( 60-64 °F).

Moisture: Begin with a wet (4) for germination, then reduce to a moist (3) on day 6. As the seedlings become fully developed with expanded cotyledons, the moisture level can be decreased further to a medium (2). Alternate between a wet (4) and a medium (2).

Humidity: Ensure high humidity of 95-100 % until day 6, then reduce to 40-60 %. Provide proper ventilation and horizontal airflow to improve oxygen levels in the media.

Light: Light is not necessary for germination but can be beneficial if using a germination chamber as it will reduce stretch and improve seedling quality. Provide light levels of 2,000-2,500 ft. candles (20,000-25,000 lx) which can be increased to 4,000 ft. candles (40,000 lx) before transplanting.

Fertilizer: Maintain low pH level to avoid chlorosis. Begin feeding once germination is complete with 100-175 ppm N and maintain an EC of less than 1.2.

Plug Bulking and Flower Initiation: Maintain optimal conditions during the vegetative stage from cotyledon expansion to flower initiation. When the seedlings root to the edge of the plug and reach the 4-6 true leaf stage flower initiation will occur.

Growth Regulators: No growth regulators should be necessary in plug stage.

Fungicides: Preventative applications are recommended to control soil-borne diseases.

Media: pH 5.6-5.8, EC 1.2-1.5. Use a welldrained and sterilized medium.

Light: Provide 3,500-4,000 ft. candles (35,000- 40,000 lx) for the fastest finish.

Temperature: 16-20 °C (60-68 °F ) days, 10-13 °C (50-56 °F) nights after transplanting. Afterwards, a frost-free production with a minimum temperature of 3-5°C (38-41 °F) at night is recommended. Cooler temperatures promote a stable, compact and well-branched plant habit.

Moisture: Alternate between moisture levels wet (4) and medium (2). Let plants dry back before re-saturating to a wet (4).

Humidity: 40-60 % humidity is ideal.

Fertilizer: Start feeding one week after transplanting. Apply regularly 175 to 225 ppm N by using predominantly nitrate-based fertilizer with low phosphorus. If needed, alternate with a balanced ammonium and nitrate-based fertilizer to encourage growth and balance the media pH. Maintain low pH level below 5.8 to avoid chlorosis.

Growth Regulators: B-Nine (daminozide) used as a spray at 2,500-3,500 ppm. At times tank mixes are used combining B-Nine with Cycocel (chlormequat chloride).

Fungicides: Apply fungicides as needed to control root and leaf diseases.

Common Diseases: Botrytis, downy mildew, powdery mildew.

Pests: Primarily aphids.

Post Harvest: Fertilize with potassium nitrate at 100 ppm 1-2 weeks prior to shipping.
