VEGETATIVE
Common pests: Aphids, spider mites, thrips, whiteflies, caterpillars Common diseases: Botrytis, Pythium, Rhizoctonia, Thielaviopsis , Powdery mildew
Plant growth regulators (PGRs): Vegetative Sunfinity ® has good vigor and generally will need chemical growth regulation in propagation. To control growth after rooting, sprays of B-Nine ® WSG (2,500-3,500 ppm) are usually sufficient. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue. Bonzi ® (paclobutrazol) media sprenches at 0.5–1.0 ppm at 2.5 to 3 weeks after sticking can be applied to maintain control of internode growth.

Estimated finish crop time is from transplant of a 105-cell tray and finished at an average daily temperature (ADT) of 69 °F (20°C).
Example crop schedule for a 2.5 quart WEEKS FROM TRANSPLANT DESCRIPTION
Provide average daily temperatures of 69 °F (20 °C) and DLI levels above 15 mol·m -2 ·d -1 . An optional pinch could occur at transplant. Apply preventative fungicides and insectides. Sprays of B-Nine ® WSG (2,500–5,000 ppm) or Sumagic ® (20–30 ppm) can be used to control growth. Evaluate plants and apply a Bonzi ® drench at 1 to 2 ppm to maintain controlled growth. Drop temperature if needed to help control growth.

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: Optional; pinching can be done as early as at transplant or within 2 weeks of transplant. Pinching delays finish by 7–10 days, but helps to reduce plant height and increase branching. Plant growth regulators (PGRs): Vegetative Sunfinity ® has good vigor and generally will need chemical growth regulation. Sprays of B-Nine ® WSG (2,500–5,000 ppm) or Sumagic ® (20–30 ppm) can be used to control growth. Bonzi ® (paclobutrazol) drench at 1–2 ppm at 3–4 weeks after transplanting; if needed Bonzi ® drench at 1–2 ppm to hold size at finish. Tech tip: For earliest flowering, provide long days, high light levels, and warm temperatures. Preventive fungicide applications for Powdery mildew are recommended, especially in high humidity environments. Palladium ® and Heritage ® fungicides have all been effective at suppressing pathogens. Insecticides, such as Avid ® 0.15 EC, Mainspring ® GNL and Flagship ® 25WG, are effective. Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 2 and 3. 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.
