To ensure a proper growth we suggest a minimum of 12h of light on maximum light intensity per day. If your plants' leaves have a lighter green color and/or the plant shows an elongated growth and the stems and leaves are softer to the touch, this is usually a sign that the plants do not receive enough light and are searching for a light source. Ideally, we recommend setting the light to shine 14-16 hours per day on maximum light intensity. The more light the plants receive, the quicker they will grow.
