Plant Types  




Culture Information
Pre - Finished Plants
Temperature
Night: 55 - 60° F (13 - 16° C) Day: 65 - 75° F (18 - 24° C) (Night temperatures are crucial for optimal crop-time. Short days with cool temperatures will extend crop-time. Long days with warm temperatures will shorten crop-time.)
Humidity
60 - 80% relative humidity. Keep foliage dry at night. Provide sufficient air circulation
Light
Grow in full sun. Insufficient light (under 4500 foot - candles) will add croptime and can cause poor branching. Daytime HID lighting is helpful.
Fertilization, Week 1 - Finish
Mix of calcium nitrate and potassium nitrate with 1 PPM of boron, (100 - 150 PPM - N) on every other watering, or (200 - 300 PPM - N) on every third watering.
Pinching
No pinching is required. Grooming may be necessary to remove some premature lateral buds.
Spacing
Space and finish at 6" x 6". Romance series varieties may require more space.
