During Stage 1, maintain media moisture at level 4 and RH at 80%. Saturated level 5 media moisture and reduced or fluctuating humidity in Stage 1 can decrease germination and uniformity. Upon removal from germination chamber, place in propagation house with bottom heat at 65-68°F/18-20°C media temperature. Use light mist to maintain humidity, allowing media to dry to moisture level 3.5 and mist at level 3. Maintain under mist for up to 3 weeks as this variety germinates slowly in 2 to 3 flushes. Spray fungicide to prevent damping off. For forcing info: See Perennials Forcing Guide. During Stage 1, maintain media moisture at level 4 and RH at 80%.

Use light mist to maintain humidity, allowing media to dry to moisture level 3.5 and mist at level 3. Maintain under mist for 7 to 10 days. This is a non-erratic germinator. Spray fungicide to prevent damping off. For forcing info: See Perennials Forcing Guide. For forcing info: See Perennials Forcing Guide. Cover seed with plug media. Grow plants under daily average temperature above 68°F (20°C) and keep media moist to wet. Use PGRs in warmer conditions from true leaf stage onwards: tank mix of chlormequat chloride 300 ppm and daminozide 2,500 ppm.

For forcing info: see Perennials Forcing Guide. For scheduling info: see Lavender scheduling tool. Spray damp-off fungicide. Provide good ventilation and active respiration in plug production. Grow on the dry side, with watering in early morning, to allow plugs to dry up during the day. If respiration and fertilisation are too low, Lavandula angustifolia can show "black spots" on cotyledons due to root pressure damage. This is reversible with improved ventilation and higher fertilisation. At sowing, do not cover the seeds too heavily, as it will significantly decrease germination. At Stage 1 germination, pull from the germination chamber at 10 to 15% visible radicle emergence and grow at 60 to 65°F (16 to 18°C) to avoid stretch. L. stoechas may stretch easily at higher temperatures in the early plug phase. Keep active growing environment. Spray damp- off fungicide. Genetically compact plants should not need PGRs in plug production. If needed, use For forcing info: See Perennials Forcing Guide. See Lavender Scheduling Tool at panamseed.com for finishing schedules by region. daminozide spray 2,500 ppm. High pH (> 6.8) causes chlorosis. For forcing info: see Perennials Forcing Guide.
