How To Grow Stock From Seeds

Stage 1 Sowing:

• Cover seed with a medium to light covering of coarse vermiculite to keep the seed moist.
• Allow 3 to 4 days for germination.
• Maintain a clean, disease-free environment in the seedling production area.

Temperature:

Stage 2 Germination:

• 68 to 72�F (20 to 22�C). Avoid temperatures higher than 75�F (24�C), as this will produce soft, stretched seedlings which are susceptible to damping off.

Stage 3 Cotyledon stage:

• 60�F (15�C) nights, 65 to 68�F (18 to 20�C) days.

Stage 4 True leaves:

• 60�F (15�C) nights, 65�F (18�C) days.

Hold plugs:

• 55�F (13�C) nights, 60�F (15�C) days.
The best-quality, well-toned plugs result when Stage 4 temperatures are maintained.


Light:

Supplemental lighting is not required.


Humidity:

• Maintain relative humidity (RH) at 95 to 97% until cotyledons emerge.

Soil Moisture:

• Keep the plug media moist. Do not subject the seedlings to water stress for toning, as they will not recover well.

Fertilizer:

• Beginning at Stage 3, feed seedlings twice each week, applying 50 ppm N from 14-0-14 or 13-2-13, alternating with 20-10-20 fertilizer. After the first week, increase to 100 ppm until the plugs are ready for transplant.
• At Stage 2:
Maintain EC at 0.5 to 0.75 mmhos and pH at 5.8 to 6.2.

• At Stages 3 and 4:
Maintain EC at 1.00 mmhos and pH at 5.8 to 6.2.

Growing On to Finish

Media

• Keep the media moist. Avoid conditions that are either too wet or too dry. Wet conditions can cause diseases including Root Rots, Downy Mildew and Bacterial Blight. Dry conditions can cause wilting and lower leaf chlorosis, which then exposes plants to other infections. It is critical to differentiate between lower leaf chlorosis symptoms caused by nutrient deficiency/ drought stress, or Downy Mildew.

Temperature

• Outdoor planting: Best-quality plants result during the time of year when night temperatures are in the low 50s�F (10�C) and day temperatures are in the 60 to 70�F (15 to 21�C) range for the first few weeks.
