TECHNICAL INFORMATION

Life Cycle:Perennial, first year flowering, FastraX Perennial

Sitelocation:Full sun

Garden Height:30 cm11,81 inch

Flower Size:10 cm， 3,94 inch

Natural flowertime: May - September

Crop Time:Plug crop: 5-6 weeks; Flowering pots: 14-16 weeks

Seed Form:Raw Seed

Seed Count:400 K/g

Sowing Method:1-3 seeds per plug

Germination:Stage I: 10-12 days at 18-20 °C, Stage II-IV: 12-35 days at 16-18 °C.

Plug Culture:From Stage II reduce the soil moisture, but the plug should not dry out and reduce the temperature to 18-20 °C. Do not let soluble salt level rise above 0,5 EC. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 150 ppm.

Growing On: 5-6 weeks after germination transplant 1 plant into pot (10-13 cm) or 3 Plants into container (3-5 l). For flowering production ensure good pot size, to encourage root growth, thus improving plant quality.

Media:Use a well-drained, growing substrate with 15-30 % clay, 0-15 % parts (e.g. bark, perlite, sand), 1-3 kg/m3 complete balanced fertilizer, 0-3 kg/m3 slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH 5.5-5.8.

Photoperiod / Light:Long day plants. The long day (12-16 h) supports the flower initiation while the short day supports the vegetative growth. In the early weeks of vegetative growth cultivate in short day (10-12 h) until the plants have developed good leaves. Later cultivate in long day (14-16 h) with high light intensity (20-30 klx) for flower development. Night interruption is possible. In winter additional assimilation light is required. Warm cultivation temperatures require high light intensity in short day as well as in long day for a good plant quality. Light deficiency can cause poor growth.

Temperature:Grow at 12-20 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. For wintering the root development in pots should be very good and the plants should be have 16 leaves. In spring the plants start to grow for 7-8 weeks at 18-20 °C during daytime and at 16-18 °C during night. Cold temperatures at 12-15 °C will increase the cultivation time, but the plant shape is more compact.

Fertilization:High fertilization levels are required. Fertilize the crop weekly with 130-150 ppm nitrogen (at 3 kg/m3 slow release fertilizer in substrate), using a complete balanced fertilizer.

Cultural Hints:Stronger plants develop when they are grown on the dry side. Excess moisture and low light levels can cause weak growth.
