Plant light for indoor growing lighting

You've almost certainly noticed a plant lamp hanging inside a grow tent. These lamps are designed to mimic natural sunlight and provide light to plants grown in the tent, from bonsai and orchids to tomato plants. But is such a plant lamp useful? That can be answered simply and quickly with "yes". Whether they're flowering, green or yielding plants, every type of greenery needs adequate lighting to photosynthesize and thrive optimally. That's why you need a plant lamp.

On the influence of light color and light temperature on growth and flower formation

The color of light has a decisive influence on the health and growth of your plant. If you recall the physics lessons from your secondary school days, you will certainly remember that daylight can be divided into different light colors. In particular, red and blue light ranges influence plants' own metabolic processes and contribute to successful photosynthesis. Every good plant lamp emits a high proportion of light with these color spectra.

In what light do plants grow best?

Healthy plant growth benefits most from illumination by daylight. However, because not everyone has a garden available or if you want to overwinter cold-sensitive plants indoors, a sufficient supply of daylight - especially during winter months - is usually not possible without an additional plant lamp. Consequently, houseplants must be grown under artificial plant light. In terms of plant cultivation and plant care, 3 light colors have proven to be necessary:

1. Light temperature 6500 Kelvin - Cold white light: This plant light is needed with regard to the cultivation and propagation of cuttings.
2. Light temperature 3500 Kelvin - Warm white light: Universal light for all stages of development with emphasis on growth - from sowing to flowering/fruiting.
3. Light temperature 2500 Kelvin - Orange-red light: Special color spectrum of a plant lamp that stimulates flowering and fruiting.

Can I use a daylight plant lamp for my plant lighting?

You're sure to have gotten your hands on daylight lamps at the lamp store or a well-stocked hardware store. A daylight plant lamp can be an emergency solution, but it does not replace professionally installed plant light. The reason for this can be found in the composition of the light. Where a dedicated plant lamp has a high proportion of red and/or blue light, many daylight lamps waste energy by emitting light from the yellow-green spectrum. This is worthless for plants and cannot be used in their metabolic processes.

Special case LED plant lamp - wavelength and light spectrum of plant light

While the color temperature of sodium vapor lamps is specified in Kelvin, one often searches in vain for this data for an LED plant lamp. This is due to the fact that with regard to LED lamps, it is not the color temperature but the emitted wavelengths that are decisive for their light spectrum. For indoor growing without daylight, plants predominantly require blue light with a wavelength of around 400 - 490 nm as well as red light with around 640 - 700 nm within the scope of their photosynthesis.

Various systems for lighting grow facilities

There is not THE plant light that can do everything and is suitable for everything. Depending on the size of the plant and the characteristics of the premises in which it is to be illuminated, different systems offer the best possible lighting.

Plant lamp with reflector and illuminant

A classic for greenhouses and indoor installations - a plant lamp with reflector and bulb. Reflectors can have different designs: an ordinary hammered reflector is characterized by reflector plates with 2-3 folded edges, which reflect the light of the growth lamps used in different directions. In contrast, models such as an Adjusta-a-Wings Avenger have large curved reflector sheets that guarantee uniform light reflection with reflection rates up to 95% without hard transitions.
The light in such plant light fittings is generated via growth lamps such as sodium vapor lamps or metal halide lamps. Products in these categories of lamps are marked in stores with the abbreviations HPS, MH, NAV and SON, among others.
In particular, the sodium vapor lamp as a grow lamp is a popular form of plant lamp for the benefit of promoting plant growth among gardeners and indoor growers. Even if this type of plant lamp does not provide the ideal light spectrum by itself, it scores with its enormous luminosity: it can reach wattages of 1,000 W and is therefore particularly bright.

Cooltube plant lamp

A Cooltube plant light is similar in design to a reflector-lamp combination. However, the highlight of this plant lamp is that the bulb is installed inside a tube made of heat-resistant glass and has connections on both sides to allow its installation in a ventilation system.
The benefit of this plant lamp lies in its air cooling - by connecting it to the exhaust system in a growroom or grow tent, the Cooltube plant light generates significantly less heat inside a grow box. Especially in large rooms in setups with more than one plant light, the tube reflectors can be excellently coupled to the exhaust system and even get their own cooling cycle with supply air fans, which promotes optimal operation. A disadvantage is that the reflector plate is rarely as wide as, for example, hammer-blow reflectors. As a result, the plant lamp has a smaller beam angle and loses some of its light energy unused due to the glass body.

Full spectrum grow LED plant lamp

The most modern plant light that is currently available on the market. An LED plant lamp offers various advantages in view of the illumination of a grow box: The installed LED modules can specifically emit the necessary color spectra without using energy in view of the production of non-usable light colors - such as the yellow-green spectrum. They are quiet, usually have their own cooling via built-in mini fans and consume only a fraction of the energy of comparable sodium vapor lamps. Almost every LED plant lamp available in Germany has a power plug and can be easily operated from the nearest power outlet. A ballast is not necessary. Some LED lamps even offer the option to manually adjust the plant light according to the needs of the plants by switching on or off additional LED fields with red or blue components.
