CROP TIME

From planting to harvest: 14 -15 weeks

STEM HEIGHT 

75 cm

PLANTING DENSITY

70 plants /m2 (6 plants/ft2).

PRE-PLANTING

Soil: Well drained soil, very well leveled surface, no clusters, at 25 cm (10 in) deep at least 25 cm (10 in.) deep.

pH: 5.5 to 6.5

Netting:  2 levels

ADDITIONAL LIGHT

Start 7 days after transplant when the plants have true leaves.  Long day conditions favors the growth of the flower buds, but the final flower

development is hastened under short days conditions. Stop the additional lightning when plants are 40 to 45 cm (15 to 17 in) high or approximately in week 9.

Add light considering a critical 14 hour photoperiod, although 16 hours is optimal.  Light can be added continuously or by pulses up to 4 additional hours at night.   6 foot-candle is required.

DISBUD

9-10 weeks after planting, remove flower bud when it appears and is well defined.  This helps shape the spray.

IRRIGATION

Apply an average daily volume  of 5 to 5.5l/m2/day according to the soil’s humidity evapotranspiration conditions and the organoleptic evaluation.

Excess irrigation can cause pathogens  development and physiological desiquilibrium.

FERTILIZATION

Excess of nitrogen can cause the plants to be susceptible to Botrytis.  A general formula can be the following:

N: 120 ppm, P: 50 ppm, K: 150 ppm, Ca: 120 ppm, Mg: 50 ppm, S: 50 ppm, Fe: 2 ppm, Mn: 2.5 ppm, Cu, Zn y B: 0.2 ppm.

HARVEST

Harvest when 40% of flowers are colored or according to client’s requirements.

POSTHARVEST TREATMENT

Hydrate stems for 2 hours in STS solution with 6 cc/l dosis. Then, hydrate in Crhyslar professional 2 solution (6 cc/l) for 12 hours in a cold room.
