Indoor plant lights UK is based on the principle of plant photosynthesis, using grow lights instead of sunlight to provide plants with full-spectrum lighting equipment.
When growers buy the grow lights for indoor plant lights UK, one of the key specifications to take into account is the range of light wavelengths and functions that a grow light emits at. Indoor plants use specific wavelengths of light to grow and so ensuring that your grow lights of choice covers the full spectrum of light wavelengths required by plants is best for growing success.
The main color functions of indoor plant lights UK:
- Red: promote longitudinal growth, elongate stem and petiole. enlarge leaves, but decrease chlorophyll contents.
- Blue: promote horizontal growth, thicken stem and petiole, increase chlorophyll contents, improve the density of stomata of the leaf.
- Orange: promote seed germination and longitudinal growth.
- Green: promote the formation of oxygen during photosynthesis.
- Violet: thicken leaves and flowers, resist extension of stem and leaves, help to form anthocyanin.
So from all, before getting a plant or starting seeds, determine the quality and hours of natural light and professional grow light’s quantity and type in your space. Meanwhile, consider plants with grow light requirements that match your indoor environment.
While a plant may tolerate lower light growing conditions, more light may be required to promote dense foliage and flowering.
A high-light plant would be suitable for brightly lit locations such as a south- or southwest-facing windows.
You may be able to start seeds without artificial lighting, but seeds that need more time indoors, such as tomatoes and peppers, may become leggy without extra grow lights for indoor plant lights UK. High-light areas can be warm, making plants dry out faster. Check these plants more frequently and water when soil is dry. It is better for indoor plants’ growth speed.
Choose factors of indoor plant lights UK:
1. Light intensity:
Light intensity is the brightness of light. The amount of light produced by a bulb is measured in a variety of ways and, unfortunately, two different bulbs may report their light output using different measurements, making it hard to compare. The distance between a light source and a plant impacts the light intensity.
While there are many ways to measure light, a few common measurements you are likely to see include:
PPF (photosynthetic photon flux) is a measure of how much plant-usable light is released by a bulb per second and is measured in micromoles of light per meter per second (umol m-2s-1). You may also see PPFD (photosynthetic photon flux density), which is a measure of PPF as it reaches a surface like a plant leaf. PPFD goes down as your plants get further away from the light source.
Foot-candle is the amount of light received by a 1-square-foot surface located one foot away from a light source equal to one candle. It’s not used as frequently though you may find this measure in older reference books.
Lumens are less relevant when considering lighting for plants. Lumens measure how bright the light is to the human eye, and do not measure some of the important wavelengths that plants need to grow.
Watts are a measure of the amount of energy needed to produce light, rather than a measure of the actual intensity of the light. Light bulbs should report both watts and another measure of light intensity such as PPF, lumens or foot candles. A more efficient lightbulb will produce more light with fewer watts of energy.
2. Distance from light source:
Keeping sufficient distance between plants and a light source is especially important when using bulbs that produce a lot of heat, like incandescent and high-pressure sodium. But even with LED and fluorescent lights, maintaining a proper distance helps to ensure healthy plant growth.
Seedlings: 4-6 inches (move your light up regularly as they grow)
Hydroponic lettuce and herbs: 6-12 inches
Foliage houseplants: 12-24 inches
Flowering houseplants: 6-12 inches
3. Light quality:
Light quality refers to the wavelength or color of light. The light spectrum is composed of red, orange, yellow, green, blue, indigo and violet light. Sunlight provides all colors of light.
The part of the light spectrum that plants use is called Photosynthetically Active Radiation, which is composed of primarily red and blue light.
As lighting technologies have become more efficient, grow lights that only emit light from the red and blue wavelengths of the light spectrum have become more common.
Check the packaging to see what type of light is emitted by a grow light before buying it; grow lights tend to be labeled as blue, red, or white/balanced light.
Blue light or mixed light bulbs are suitable for starting seeds and leafy greens, as well as non-flowering house plants.
Red light or mixed light bulbs are suitable for promoting bud formation in flowering plants as well as keeping the plants shorter.
White lights or mixed/balanced light bulbs are suitable for most plants at any stage of growth.
4. Light duration
Light duration (photoperiod) is the number of hours of light a plant needs per 24-hour period. Plants are classified by photoperiod into three categories for flowering response: short day, long day, or day-neutral.
Short day grow lights for indoor plants UK, such as chrysanthemum, Thanksgiving and Christmas cacti and poinsettia, require short days to flower. You cannot reflower them indoors unless they are grown in short days.
Long day plants, such as African violets, gloxinia and tuberous begonias, flower when the daylight exceeds the hours of the night period.
Day-neutral plants are insensitive to day length differences for flowering and include indoor plants such as flowering maple (Abutilon), Crossandra, and gerbera daisies.
Grow lights for Indoor plant lights UK require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die. Please choose your best grow light for indoor plants is the most important thing for all growers in the world.
