Plug Production
Plug Tray Size Titan vinca plugs are best produced in 392-cell plug trays.

Media:Use a well-drained, disease-free, soilless medium with a pH of 5.8 to 6.0 and a medium initial nutrient charge (EC) of 0.75 mmhos/cm (1:2 extraction).

Sowing:Cover the seed with coarse vermiculite. Allow 3 to 5 days for germination.

Temperature
Germination: 75 to 78°F (24 to 25°C), Cotyledon stage: 72°F (22°C), True leaves: 70 to 72°F (21 to 22°C)
At germination, the soil temperature should be maintained at 70 to 72°F (21 to 22°C) until transplant.

Light
Stage 1: Light is not required for germination
After germination: 2,500 to 3,000 f.c. (25,000-30,000 Lux), Seedling maturity: Up to 5,000 f.c. (50,000 Lux)

Humidity:Maintain 95 to 97% relative humidity (RH) until cotyledons emerge.

Soil Moisture:Keep soil moisture high at radicle emergence, then reduce moisture levels after cotyledon development. Do not allow seedlings to wilt.

Fertilizer
Stages 1 & 2: Maintain an EC of 0.50 to 0.75 mmhos/cm and pH of 5.8 to 6.0.
Stages 3 & 4: Maintain an EC of 1 mmhos/cm and pH of 5.8 to 6.0.

Growth Regulators:Not required.

Growing On to Finish
Container Size:606 jumbo cell packs or 4-in. (9-cm) pots

Media:Use a well-drained, disease-free, soilless medium with a pH of 5.8-6.0 and medium initial nutrient charge.

Temperature
Night: 65 to 68°F (18 to 20°C), Day: 75°F (24°C) or above

Light:Keep light levels high.

Irrigation:Maintain even moisture. Avoid excessive wetness.

Fertilizer:Feed plants weekly with 200-300 ppm N in a complete fertilizer, again maintaining a pH of 5.6-6.0.

Growth Regulators:None required.

Crop Scheduling
Sow to transplant (392-cell plug): 5 weeks
Transplant to finish in a pack: 3 to 4 weeks
Transplant to finish in a 4-in. (10-cm) pot: 4 to 5 weeks
Total crop time from sow to finished container: 7 to 10 weeks. The timing is dependent on the temperature and light provided.
