King White, Queen Red
From plating to harvest: 12 Weeks.
80 plants/m2 net (8 plants/ft2).
Soil: Loose and well-drained soil, at least 25 centimeters deep.
pH: 5.5 to 6.5
Netting: 2 levels.
Use well rooted plugs with 2 to 3 true leaves and no higher than 5 centimeters high. If the plug is elongated, plant deeper until the cotyledon to make them grow straight.
Night temperatures below 13°C (55 F) during 2 weeks cause good coloring as well as reducing moisture and fertilizer.
Have in mind that Nitrogen promotes green growth and reduces intensity of flower color.
Thinning of leaves after transplanting is necessary. Remove 8 to 10 leaves from the bottom of the stem when the plants have 15 to 20 true leaves. Remove leaves 3 to 4 times during the crop cycle.
Start with overhead irrigation 4 weeks after planting to moisture soil evenly accordingly to the soil’s organoleptic sample.
Start 5-7 days after planting. the amount of water will depend on environmental conditions, evaporation and transpiration. During the first 6 weeks, fertilize and irrigate completely (5,0-5,5 l/m2/day).
At week 7, reduce fertilization to 50-100% according to the fertilization of the soil. Additionaly, in order to have thinner stems and tighter heads, reduce irrigation to 50%.
Start 1 week after planting, and continue fertilizing until week 7.
A general fertilization formula can be:
N: 80 ppm; P: 40 ppm; K: 160 ppn; Ca: 120 ppm; Mg: 60 ppm; S: 50 ppm; Fe: 2 ppm; Mn: 2.5 ppm; Cu, Zn y B: 0.2 ppm.
EC: 1 to 1.3 dS/cm
It must be done when heads have formed and leaves show good coloring. Cut stems and remove lower leaves if necessary, leaving 2 or 3 outer leaves around the top.
POST HARVEST TREATMENT
Hydrate the stems in a solution with Chrysal professional 2 at a dose of 6 c.c/l, during 12 hours at cold room.
PACKAGING AND STORAGE
Pack in bunches of 5 stems.
