Choosing the Best Indoor Lighting for Plants
Proper lighting is essential for the growth of plants, without which plants cannot flourish. In the absence of sunlight, maybe due to location or season, artificial lightning may be used to achieve the same purpose.
Criteria for choosing light
There are different types of light needed by different plants to imitate the light from sunlight in colors and intensity. As a grower, you need to understand how plants absorb light to know which type of light to choose and at what intensity. For instance, violet and red colors are necessary for photosynthesis. The quantity of the grow light to be received should also be monitored because excess or insufficient of any particular color poses a threat to the plants.
It is imperative to know the intensity of light to use. You should purchase the right voltage of the grow lights and adjust them properly as per distance from the light to ensure proper plant growth.
The duration of exposure to light varies for different plants just as their exposure to sunlight is not constant.
The different Types of Indoor Plant Growing Lights
There are so many different types of light for indoor plants that you might get confused while choosing the proper hydroponics light to suit your indoor plants. We hope this will help you make the right choices.
High Intensity Discharge Lights– This group of lighting system can be expensive but suitable for commercial horticulturists. It is of three types:
- High Pressure Sodium (HPS)
- Ceramic Metal Halide (CMH)
- Metal Halide (MH)
The HPS is the commonest of the three because it has high intensity red and orange light which is most suitable for flowering and fruiting plants. The CMH is the new entrant that can be used solo for the whole life span of the plant due to its blended spectral output. For this reason, it is gradually replacing the MH and HPS. The MH on its part is best for blue light which suits plants at their vegetative stage.
They are common for home lighting. As an indoor plant growing light, it is best suited for growing low-light indoor plants because they produce more of heat than light. This makes it unsuitable for plants that require plenty light for growth, otherwise, it will cook them up. Instead, use them for plants that need more heat and less light. In addition, they have a good wavelength of red light.
LED indoor grow lights have metamorphosed over the years to become a viable source of light for indoor growing plants. LED provides an efficient but expensive lighting for indoor plants, backed by top notch technology. They are easy to mount owing to their small size and provide red and blue lights. For some green houses, LED lighting is the only suitable means of lighting. The good news is that LED technology continues to evolve to give growers better results.
Fluorescent grow lights are very popular among lay plant growers. They emit cool lights (blue, yellow, green) which can be situated close to the seedlings and warm light of red and orange. Your choice should depend on the light requirement of each plant. Fluorescent grow lights are good for plants with low and medium light requirements and seed starting.
They consume less energy than incandescent lights and are cheaper. They come in various sizes; the narrower ones are brighter and more efficient than the larger ones.
Full Spectrum Fluorescent Indoor Lights
This modern fluorescent lights provide red light which enhances plant flourishing and when combined in a fixture, provides balanced lighting of cool and warm lights for all round growth. They last long and are energy efficient.
