Plants Need Lighting, Too

Sometimes it’s hard to provide the right type of lighting for our plants due to different reasons.  For example, seasonal changes or lack of direct sunlight could be one of those reasons. Whether you are dealing with decorative house plants for a long time or it is your first time trying to grow home plants, take a look at our recommendations.

Light bodies with conventional lamps with incandescent light bulb

Traditional lamps with incandescent light bulbs are good for lighting of spaces or growing plants that don’t require strong light such as Vines, Ferns, and Dracaenas. The regular lamps have limited luminous flux and are ineffective with the high requirements for light of other plant types. These lamps emit only 10% of their energy as light and 90% as warmth. So, if you have no intention of cooking the plant, don’t use them, unless you want to grow plants that love light – such as tropical plants, cactuses and other juicy, citrus fruits.

Lighting for Plants

Luminescent Lamps

Luminescent lamps are ideal for plants with low to medium requirements for light, just like the African violets. They are also appropriate in the initial stages of growing vegetables outside. These light bodies normally are long; they look like pipe lamps in a couple of different sizes – including T5, T8 and T12.

The thinner the pipe, the more effective and bright it is, thanks to the smaller area. In addition, luminescent pipes use 75% less energy compared to the common lamps. For example, 25W luminescent pipe radiates as mush light as a 1000W simple light bulb. The T5 standard reaches almost double the light compared with the simple luminescent pipe. Since they radiate light with color temperature 6500 Kelvins, this means that they have full spectrum of light and they are with a very high light intensity.

Lamp for a Plant

A Kelvin is a metric unit for color temperature and it’s used for measuring the luminous flux. It’s a scale for measuring the warmth or the cold of the light source. The higher the Kelvin degrees – the bluer or “colder” the lamp is. The lower the degree, the redder or “warmer” the lamp becomes.

When you are growing most of the home plants, use lamps with color temperature from 4000 to 6000 Kelvins because their lamps will radiate almost the entire light spectrum – the cold and the warm light. With these lamps you can recreate the greenhouse lighting. Culinary herbs, starters or green plants can be grown almost thorough the whole year through these lamps. Plants that need lots of light such as orchids, citruses and even carnivores develop well under these full-spectrum lamps. When you are dealing with plants that are just planted or Spermatophyte, place T8 or T5 lamps from 5 to 10cm from the plants in order to recreate natural light. For plants that are already grown, including herbs and flowers at home, place the lamps 30-60cm apart.
