- 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.
