Technical Guide

Germination: Optimum conditions for seedling development, beginning on the day of sowing until radicle emergence. Expect germination in 6-10 days.

Cover: No cover is required. Watering the seeds for 24 hours before sowing can be helpful.

Sowing method: 4-6 seeds per plug.

Media: pH 5.8-6.5; EC <1.0

Temperature: 20-22 °C (68-72 °F) until radicle emergence. A day-night difference of 30 °C (86 °F) during day and 20 °C (68 °F) at night could be helpful. After germination, reduce to 18-20 °C (64-68 °F) during day and night.

Moisture: Begin with a wet (4) for the first days of germination. Alternate between moisture levels moist (3) and medium (2) to maintain a good wet to dry cycle. Avoid overwatering.

Light: Light is required for germination. Provide light levels of 30,000 lx which can be increased to 50,000 lx before transplanting.

Fertilizer: Maintain an EC <1.0. Use a balanced fertilizer. Feeding should start <100 ppm N.

Growth Regulators: Not required.

Media: pH 6.5-7.0; EC 1.0-1.2

Temperature: 12-15 °C (54-58 °F) during day and night. Cool temperatures are required to get compact, well-branched plants with stable stems in pots.

Moisture: Alternate between moisture levels moist (3) and medium (2) to maintain a good wet to dry cycle. Avoid overwatering.

Light: High light levels shorten the crop time.

Fertilizer: Regular fertilization is not needed. If desired, a light application of a balanced fertilizer can be used.

Growth Regulators: Not required.

Pests & Diseases: Aphids, rust

Moisture Codes

Saturated (5) Water is easily observed when finger is pressed on cell. Water moves freely from the top of the plug to the bottom.
Wet (4) Media looks black and is not glistening. The media feels wet to the touch but there is very little water movement.
Moist (3) Water is not easily visible. When finger is pressed on the cell there is very little movement from top to bottom.
Medium (2) Media is not black, but now looks medium brown. There is no water movement when pressed with finger.
Dry (1) Media has changed color to a very light brown and is dry to the touch.
