Germinates at 68-72 °F (20-22 °C) in 28 days. During Stage II lower temperatures to 65-70 °F (18-21 °C). Plugs should finish in 10-12 weeks. DO NOT VERNALIZE PLUGS.
Growing on
Grow on 65-70 °F (18-21 °C) - DO NOT VERNALIZE PLUGS
Media
Use a friable, coarse-fibered perennial media containing 10-20 % clay, 0-15 % organic matter (such as wood chips or bark humus), a multiple balanced fertilizer at 1-1.5 kg per m³, Radigen at 100 g/m³, and a coated time release fertilizer (4-5 months) at 3-4 kg; pH value: 5.5-6.0
Temperature
15-18 °C. Non-frost-free overwintering: Cover the plants with a non-woven cloth to protect against direct sunlight. Frost-free overwintering: 3-5 °C
Fertilization
Heavy feeder. Apply 150-200 mg N per l of a balanced multiple fertilizer containing a high percentage of nitrate nitrogen. Ensure a good potassium supply. Avoid overfertilization with nitrogen. Use 1-2 applications of sequestered iron to avoid iron deficiency.
