Emergence to cotyledon expansion= 120µS/cm (1part soil, 5 parts water). Cotyledon expansion to true leaf growth = 170µS/cm. Plug finish = 300µS/cm
In plug trays (180-384 tray) it is not necessary to cover the seeds, but to obtain optimum humidity we recommend to cover the trays with a thin layer of Vermiculite.
Cover the trays with plastic and place them in darkness in a growing chamber.
16 degrees Celcius 18 degrees Celcius. Temperature above 20 degrees Celcius may reduce the germination rate.
Time to germinate
8-10 days. When moving the trays from the growing chamber to the greenhouse, it is recommended to cover with a shading net (under bright conditions) in order to keep a suitable humidity and to protect the young plants.
Plug Finish Time
6-7 weeks in a 384 tray ; 7-8 weeks in a 308 tray ; 8-9 weeks in a 180 tray.
Lightly fertilized peat with a good, well-draining structure. pH 5,5-6. EC 400µS/cm.
6-9 weeks after sowing the young plants are ready to be potted. If an outdoor production is requested, we recommend hardening of the young plants in a shaded area before potting. After potting outdoor, cover the plants with a shading net until the plants are well established. Make sure the plugs and fresh potted plants are well watered for a good start.
Growth regulation, if necessary, is possible, if allowed, with products based on propiconazol (25 %), at a dose of 0,015-0,1%.
Chlorosis: iron deficiency.
Insects: aphids, mites, thrips, miners, white flies, caterpillars.
Bacteria: leaf spots, especially at low temperatures.
