Recommended tray size: 288–cell tray Seeds per cell: 1–2 Young Plant Production Stage 3 & 4 Temperature
Dottie ™ Warm Rose
Fertilizer: 75–100 ppm N Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 3 and 4. 2 - MEDIUM: Soil is light brown in color, no water can be extracted from soil, and soil will crumble apart. 3 - MOIST: Soil is brown in color, strongly squeezing the soil will extract a few drops of water, and trays are light with no visible bend. Pinching: No Plant growth regulators (PGRs): If necessary, plants will respond to sprays of B-Nine ® WSG (daminozide) at 2,000 ppm, or a Bonzi ® (paclobutrazol) spray at 5 ppm. Plug grow time: 4–5 weeks in a 288–cell tray Comments: No vernalization required. Although, Dottie ™ digitalis can be transplanted in late summer–early fall for faster flowering in the following year. Bulking and Vernalization Vernalization: Not required (First year flowering) Finishing Temperature Day: 68–70 °F (20–21 °C) Night: 64–66 °F (18–19 °C) Average daily temperature: 66 °F (19 °C) Lighting
