The Cresta series is notably earlier lowering than its closests rivals, therefore saving valuable time, space and cost in production. Meanwhile the large showy lowers, great uniformity and excellent garden performance is everything that modern growers and consumers demand. A great choice for pots, packs and the garden.

Plug Production: 288 plugs
Sowing/Media:
Use a well-drained, disease-free, peat based plug medium with pH 6.0-6.2, EC <0.75mmhos. Cover seed with a thin layer of vermiculite, otherwise the seedlings will root into the vermiculite and make transplanting difficult. Keep medium uniformly moist until seedlings are hooking above the covering, media temperature should be 68-72°F (20-22°C), keep light levels <1500 f.c. Dry down slightly to avoid stretch, keep media temperature at 68-72°F (20-22°C), germination should be complete in 5-7 days. Allow media to dry further between irrigations to improve rooting and control stretch, but avoid wilting. Media temperature can be dropped to 65-68°F (18-20°C), light levels should be <3000 f.c. Fertilize with 100-150ppm N from 15-5-15, 17-5-17 or 13-2-13, keep media pH at 6.2-6.5 no lower and EC <1.5mmhos. Practice good wet/dry moisture cycle, media temperatures can be lowered to 60-65°F (15-18°C), keep light levels <3000 f.c. Fertilize with 100-150ppm N from 13-2-13 to help tone the seedlings. Growth can be controlled naturally by good moisture management. If needed, use sprays of B-Nine (1500 – 2500 ppm), A-Rest (3 – 10 ppm), Bonzi (10 – 20 ppm), or Sumagic (2 – 7 ppm) to control growth. It is best to run your own trials to avoid overdosing, as weather and cultural regimes can affect the requirements.

Growing On to Finish: Packs, 4” (10cm) pots
Media:
Use a well-drained, disease free, peat-based growing mix with pH 6.2-6.5, EC 1.5mmhos
Temperatures:
Temperatures for rooting out after transplant should be 65-68°F (18-20°C). These can be lowered to 62-65°F (16-18°C) for growing on.
Light:
Light levels should be 3000 - 5000 f.c. as a guide.
Irrigation:
Practice a good wet/dry moisture cycle, avoiding wilt.
Feed 1–2 times per week with 150 – 200 ppm N from 15-5-15, 17-5-17, or 13-2-13. Keep media pH 6.2 – 6.5, and media EC 1.5 – 1.75 mmhos. Growth can be controlled naturally by good moisture management. Use sprays of B-Nine (2500 – 5000 ppm), Bonzi (15 – 30 ppm), or Sumagic (5 – 10 ppm) as needed. Drench with Bonzi (2 – 5 ppm) or Sumagic (1 – 2 ppm) when plants are up to size and flowering. It is best to run your own trials to avoid overdosing, as weather and cultural regimes can affect the requirements
