Plug Production: 512 or 288 plugs
Sowing/Media:
Use a well-drained, disease-free, peat based plug medium with pH 5.5 – 5.8 and EC <1.0 mmhos. No need to cover seed. Media should be moist, almost saturated, temperature should be 72-75°F (22-24°C), light levels of <1500 footcandles may be beneficial for germination , maintain high humidity. Dry down surface slightly once seedlings are hooking to improve rooting, maintain temperature at 72-75°F (22-24°C) and light levels at <1500 footcandles Allow media to dry further between irrigations to improve rooting, branching and budding and control height and floppiness, media temperature should be 68-70°F (20-22°C), light levels should be 2500-3000 f.c. Fertilize with 100-150ppm N from 17-5-17, 13-2-13 or similar avoiding high levels of ammonium nitrogen, keep media pH at 5.5-6.0 and EC at <1.25 mmhos. Make sure growing tips are dry going into the night to avoid tip abortion. Irrigate as stage 3, media temperatures down to 62-65°F (17-19°C), keep light levels at 3000 f.c. Fertilize as required but use 13-2-13 for more tone. Sprays of Bonzi (5-10 ppm) or Sumagic (1-2 ppm) can be used if needed.
Germination Stage 1: (3-5 days)

Growing On to Finish: Cell Packs, 4 inch (10cm) pots, Baskets/Containers
Media:
Use a well-drained, disease free, peat-based growing mix with pH 5.5-6.0, EC <1.5 mmhos. Keep temperatures at 65-68°F (18-20°C) for rooting out and lower to 62-65°F (17-19°C) for growing on. Avoid cooler temperatures as the upper leaves will turn yellow. Keep light levels around 3000 f.c. any higher may cause leaf scorch/burn and lower yellow leaves Practice a good wet/dry cycle to achieve best rooting, height control and flowering. Impatiens can tolerate mild wilting between irrigations. Feed once a week with 150 ppm N from 17-5-17, 15-5-15, or 13-2-13. Avoid over feeding as plants will become more ‘leafy’ and produce less flowers. Keep media pH 5.5-6.0, EC <1.5 mmhos, watch for lower yellow leaves to determine whether fertilizer is needed. Growth can be controlled by managing moisture, fertilization and temperature. If PGR’s are required, sprays of Bonzi (5-10 ppm) or Sumagic (1-2 ppm) will control growth. When plants are mature, a Bonzi drench (1-2 ppm) will control height without affecting flowering. It is advisable to run your own trials to find the most suitable application rates and frequencies to suit your programs in your conditions.
