Propagation of Unrooted Cuttings

Root emergence: 7–14 days Rooting hormone: Not recommended Bottom heat temp.: Not necessary.

Misting: Mist schedules vary depending on light and temperature conditions. Apply just enough moisture to rehydrate the cuttings and keep them from wilting. Cuttings should be hydrated and in a non-wilted stage within 24 hours after sticking. Cuttings that continue to wilt heavily after 24 hours will callus unevenly and will be delayed in rooting. CapSil ® (spray adjuvant) can be sprayed on the cuttings at a rate of 2–4 oz/100 gal within 1–2 days after sticking to help in rehydration of the cuttings. Misting should be significantly reduced after 3–4 days and after cuttings become fully hydrated. Rec. tray size: 105-cell (30 mm) Propagation timing: 3–4 weeks for a 105-cell plug; add more rooting time for significantly larger plug sizes. Temperature

Day: 74–76 °F (23–24 °C) Night: 68–70 °F (20–21 °C) Lighting Day extension lighting: Not necessary

Light intensity: 1,000–1,200 foot candles (200–250 µmol m -2 s -1 ) for the first two weeks after sticking or until root development occurs. Light levels can be increased up to 3,000 foot candles (600 µmol·m -2 ·s -1 ) as rooting increases and the cutting matures. Daily light integral (DLI): 4–6 mol·m -2 ·d -1 for the first two weeks after sticking or until root development occurs. DLI can be increased to greater than 12 mol·m -2 ·d -1 after root formation. Media pH: 5.6–6.0 Media EC: SME EC: 0.9–1.3 mS/cm, PourThru EC: 1.4–2.0 mS/cm Fertilizer: Begin fertilization at 100 ppm nitrogen when roots become visible. Rates can be increased up to 200 ppm nitrogen after roots become well developed. Use primarily Cal-Mag ® Plus (calcium nitrate + magnesium nitrate) fertilizers in propagation to prevent unwanted stretch. Pinching: Optional Plant growth regulators (PGRs): Florel ® sprays can be used to substitute at rates of 300–500 ppm or B-Nine ® WSG sprays can be used to reduce stem elongation with rates of 1,500–2,500 ppm.
