floranova creative plant breeding
Plug Production: 512 or 288 plugs Sowing/Media: Use a well-drained, disease-free, peat based plug medium with pH 5.5-5.8, EC 0.75mmhos. Cover seed with coarse vermiculite Germination Stage 1: (4-5 days) Keep medium uniformly moist, media temperature should be 65-70°F (18-21°C), Keep light levels <1500 f.c. until cotyledons are open. Germination Stage 2: Dry down covering slightly to improve rooting and control loppiness, maintain media temperature at 65-70°F (18-21°C), once cotyledons have opened light levels should be 1500-2000 f.c. Germination Stage 3: Allow media to dry further between irrigations, practice a good wet/dry cycle but avoid wilting, media temperature should be 60-65°F (15-18°C), light levels should be around 3000 f.c. with shading in hot weather Fertilize every other watering with 100- 150ppm N (nitrate form) from 15-5-15, 17-5-17, or 13-2-13 keep media pH at 5.5-5.8 and EC at 1.0-1.5mmhos. Germination Stage 4: Keep media on the drier side and lower media temperature to 55-60°F (13-15°C), light levels can be increased to 3000-4000 f.c. if possible. Fertilize as stage 3, avoid using high NH4 fertilizers but make sure pH is below 6.5. Growth Regulators: Cool temperatures and good moisture management should provide adequate control but if needed, sprays of B-Nine (1500– 2500 ppm), A-Rest (2–7 ppm), B-Nine (1000–2500 ppm) + Cycocel (500–1500 ppm), or B-Nine (1000–2500 ppm) + A-Rest (1–5 ppm) can be used. Weather conditions and cultural practices directly afect how much growth regulator to use, so it is recom- mended that you run your own trials.
Growing On to Finish: Packs, 4” (10cm) pots Media: Use a well-drained, disease free, peat-based growing mix with pH 5.5-5.8, EC <1.5mmhos. Temperatures:
Keep media temperature at 60-65°F(15-18°C) until roots have developed and then lower to 55-60F(12-15°C) to grow on. Grow- ing cool produces a much better inished product, but the crop time will increase if the temperature is below 55-60F(12-15°C) Light: Keep light levels at 3000-4000 f.c.. Provide shade if light levels are higher to keep temperatures down. Irrigation: Practice a good wet/dry moisture cycle to aid root development and control height. Fertilizer: Fertilize once a week with 150ppm N (nitrate form) from 15-5-15, 17-5-17, or 13-2-13 but keep media pH at 5.5-5.8 deinitely <6.5 and media EC no higher than 1.0-1.5mmhos. Growth Regulators: The Tiger Eye varieties have a naturally slower growing habit when compared to Bel Viso and therefore should not require PGR applications if the ideal temperatures and moisture levels can be achieved. If grown under high temperatures, unwanted leainess may occur, so if necessary sprays of B-Nine (2500–5000 ppm), A-Rest (3–10 ppm), B-Nine (1500–2500 ppm) + Cycocel (750–1500 ppm), or B-Nine (1500–2500 ppm) + A-Rest (3–7 ppm) will give good control. Weather conditions and cultural practic- es directly afect how much growth regulator to use, so it is recommended that you run your own trials. Pests: Aphids, Thrips, Spider Mites. Fungus Gnats and Shore Flies during the plug stage. Diseases: Pythium, Thielaviopsis, Botrytis, fungal leafspots, Downy and Powdery mildew.
