How long should I leave the Highland™ on each day?

Light cycles are used to simulate the conditions of day and night for indoor plants. We highly recommend the use of an electrical 24-hour timer (included) to create a repeatable light cycle.

Most plants grow in two stages, the vegetative stage and the flowering stage. During the vegetative growth stage, the plant is focused on growing in preparation for flowering. Some plants can be left in the vegetative stage indefinitely with no adverse effects. The flowering stage is initiated when the light cycle changes into the critical light period, as explained below. This change will cause your plant to focus completely on making flowers and seeds for reproduction.

There are three types of plant responses; short-day, long-day, and day-neutral. The first two types have a critical light and dark period associated with them and can vary from plant to plant. This critical period will determine when the plant switches from the vegetative stage to the flowering stage. Day-neutral plants are generally unaffected by light cycles and flower when the plant is mature. If you find that it is difficult to flower a short-day plant due to a light flash at night, we recommend flowering in a closet or grow tent.
