Estimated finish crop time is from transplant of a 105-cell tray with 2 cuttings per cell and finished at an average daily temperature (ADT) of 66 °F (19 °C).
Transplanting: Transplant directly into the finished container. Place the rooting media slightly below the level of media in the container. Make sure that the root ball is covered and that the liner is situated in the center of the pot. Media pH: 5.8–6.2 Media EC: SME EC: 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm Fertilizer: 200–250 ppm N Pinching: Yes, 1 pinch is recommend 7–10 days after transplant. Plant growth regulators (PGRs): PGRs are not usually required. Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 3 and 4. 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. 4 - WET: Soil is dark brown but not shiny, no free water is seen at the surface of the soil, when pressed or squeezed water drips easily, and trays are heavy with a visible bend in the middle. Common pests: None Common diseases: Botrytis, Rhizoctonia, Pythium

DESCRIPTION
Provide average daily temperatures of 66°F (19 °C) and DLI levels above 10 mol·m -2 ·d -1 . Pinch plants when they are rooted into the pot. Inspect roots and apply a preventative overhead fungicide drench to the plant/media to prevent fungal root rot and basal stem rot.
