Grow Lights for Indoor Plants are electric lights that supply the needed orange, yellow-green and blue red and white rays. Usually the easiest and least expensive way to provide enough light for plants that do not receive adequate natural light.

Alternating light and dark conditions are extremely important to indoor growing. Grow lights for indoor plants provide the needed light for those plants. With Aquaponics, the nutrients needed can be more readily available to the growth cycle in a hydroponic growth environment. Regular light is important to the growth and development of any plant, but so is the rest or dark cycle of the light equation. Most plants need light cycles that correspond to certain grow cycles inherent to the plant itself. The night shade family of plants tend to store up light during the day, and tend to grow more in the dark cycle.


Some plants can withstand 24-hour light while seedlings and during vegetative growth cycles, but most plants require shorter light times while flowering, producing fruit and ripening. Plants need light to photosynthesize, but darkness is just as important to give a plant time to convert photosynthesized nutrients into plant growth. Remember to research what plants you want to grow, and what their specific light cycle is for them during different stages of growth.


There are several types of grow lights, and choosing which one you will use depends on the types of plants you are growing and how much light they would need if they were planted outside. Standard, or T12, fluorescent tubes are suitable for most indoor growing settings. T5 and T8 fluorescent tubes produce twice the light of standard fluorescent tubes and are sold singly, or as sets of two, four, six or eight. T5 tubes can provide light for wide planting tray systems for plants that grow to 3 feet. Compact florescent lights, or CFLs, can supply light for plants that grow to 2 feet and generate very little heat. High-intensity discharge, or HID, lights produce 500 percent more light that standard grow tubes using the same amount of electricity. They are available in two forms: metal halide, that produce the blue light that plants need for foliage growth; and high pressure sodium, whose orange-red light encourages plants to flower.
