Consider that the water-holding capacity that is best for consumer performance may be greater than what is ideal for production. Lamium prefer to be kept moist, but not constantly wet. A media EC of 2.0 is optimum. Provide a complete minor element program. Provide periodic clear water application if excess soluble salts accumulate.
Low temperatures promote 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. Pinching Trim plants only as needed to shape growth. Spacing Plants may be established pot-tight but should be spaced before foliage touches.
