From planting to harvest: 18 weeks
From pruning: 16 weeks.
8 Plants/m2 net. Plants are spaced in a quincunx pattern with 40 cms between plants.
Soil: Loose and well-drained soil, at least 25 cms deep.
pH: 5.5 to 6.5
Netting: 2-3 levels
Pinch apex when plants have 8 pairs of leaves. Four days after pinch apply GA3 at 150 ppm. A second GA3 application can be done selectively 8 days after the first application to plants with delayed growth.
Low approx. 2 to 3 cms (1 to 2 in).
If no drip system is used, to prevent diseases it must be higher (at 5 cms).
It is advised to seal with fungicides to protect from diseases.
THINING AFTER PRUNING
5 weeks after pruning, shoot selection must be completed leaving 12 to 15 uniform shoots. After selection, apply GA3 at 180 ppm.
Gypsophila respond to long day conditions. Flowers will open with 15 to 16 hours of light. One week after planting, add artificial lightning for 5 weeks.
Use overhead irrigation for the first week after planting. Then, switch to drip irrigation. Keep the soil at field capacity during the establishment of the plant.
Apply 4-5 L/day/m2 (according to environmental conditions).
Reduce irrigation to 2-3 L/day/m2 when the floral bud appears.
One week before pruning, stop irrigation and restart 1 week after pruning at 2 L/day/m2 and increasing it gradually up to 4-5 L/day/m2 as leaves appears.
When grown under greenhouse, harvest when 70 to 80% of the flowers are open.
When grown outside, harvest when 30% of the flowers are open followed by 5 to 7 days inside an opening chamber at a temperature of 76° F to 81°F and high relative humidity (50%-60%). Clean scisors twice per bed with disinfecting solution (Timsen 2 g/L).
POST HARVEST TREATMENT
Use citric acid to bring the pH down to 4.0.
EC: < 400 µS/ cm
Harvest at 70% -80% flower opening
Immediately after harvest, hydrate stems in STS harvesting solution for 24 hours.
Harvesting Solution: Chrysal AVB: 1 ml/L; AVB Booster: 1 ml/L
Then hydrate in a Chrysal Profesional 2 solution at 6 ml/L for 12 hours in a cold room.
Harvest at 30% flower opening
Apply same harvesting solutions and conditions as above, then place stems in a opening solution until desired floral opening (80%, 4/5 days).
Openning Solution: Chrysal OVB: 2 ml/L; Professional 3: 10 gr/L; Sugar: 30 g/L
Rplace the solution every 2 days.
Opening Room Conditions: Temp ≤28 ° C and RH 50%
