Cool Finish (24 hrs avg.):63°F / 17°C
Indicates minimum temperature starting two weeks after the beginning of short days. Please note that a crop grown cooler requires more time to finish (4 to 7 days), and will have smaller bracts and darker color (for example, white may turn cream-yellow). Toward the end of the crop (two weeks prior to shipping), slowly lower the temperature for green-leafed varieties to 65°F (18°C) day/night and dark green-leafed varieties to 63°F (17°C) day/night.

NOTES
CULTURE THAT WORKS
propagation
- Roots rapidly; plant from a liner at 22-24 days.
- Apply rooting hormone to the base of cutting.
- Start feed program around day 7.
- Early growth is slower than some others; may not require PGR application in propagation.
- Important to plant from liners into finished container as soon as they are well rooted.
- Uses feed aggressively; feeding should begin early in propagation around day 7.
- Failure to feed early enough will result in yellowing and hardening.
early finished growth
- Very strong-branched variety must be pinched early: at day 14-16 from a liner; at day 24-26 for direct stick.
- Failure to pinch early will result in uneven branching.
- Apply light PGR when dominant branches are 1-1.5 in. (2.5-4 cm) using Cycocel spray at 500-750 ppm; recommended to even out branches.
- Failure to do the early Cycocel applications can result in plants with more dominant bracts.
growing on
- Grows steadily once branches develop, and exhibits consistent moderate growth throughout the crop until color begins.
- Northern Climate: PGR should be limited to only Cycocel spray at 500 ppm.
- Southern Climate: Can use Cycocel spray up to 1,000 ppm. Use 1-2 spray applications of B-Nine (1,000 ppm)/Cycocel (500 ppm) before September 20
- Later applications of PGR should be straight Cycocel spray 500-750 ppm and/or Micro Bonzi drenches beginning in early October.
late growing stages
- Very strong root system; requires continuous feed until finish.
- Watch media EC; reduce feed levels to avoid rapid increase in media EC, as this indicates the plants' need for nutrition is waning.
- High EC at finish can result in root damage, reduced shelf life and possible Pythium.
- Can be held cool but will reduce whiteness. Pay attention to humidity and avoid dew point to prevent Botrytis.
