Once established and growing, do not allow soil to get too dry as this will result in damage to the foliage and flowers. A media EC of 2.5 is optimum. Alternate with calcium nitrate on a regular basis. Provide periodic clear water application if excess soluble salts accumulate. High salts can cause yellowing of lower foliage.
Low temperatures promote flowering and compact growth, but slow development.
Provide good air circulation at all times. Light Bright light is ideal for this crop. Retractable roof greenhouses and field production are suggested where possible. This should be the second pinch with the first completed during propagation. Additional pruning can be used to shape plants, correct for stretching or to time flowering.
