How much light do plants need?
Most vegetables and flowering plants need 12 to 16 hours of light per day, with flowering plants at the top end. Most plants should be given at least 8 hours of darkness a day. Plants need different amounts of light.
What is lumen in a plant?
Luminous flux refers to the total amount of visible light emitted by a lamp with a specific power. The value of luminous flux varies according to the distance and height of the plant, the size of the planting area, the type and number of plants, and the type and power of the grow light. In addition, we also clearly know which growth stage the plant is currently in to determine how much supplement light is needed.
How many lumens per square foot for a crop?

What is the vegetative stage of a plant?
The vegetative stage refers to the photosynthesis of plants to accumulate energy to promote flowering and reproduction. Plants in this period need about 2200 to 3200 lumens per square foot (or 24,200 to 35,200 lumens per square meter).
Why is it bad for plants to grow in cold weather?
The cold season is a severe test for the growth of most plants. Low temperature will inhibit the metabolism of crops to a large extent, thereby delaying growth. It is known to us all, the growth of plants is inseparable from sunlight, and sunlight determines the results of plant growth. Therefore, if the plant is planted in a dark room indoor environment, the plants cannot get the best natural light during the day, and the plants will not develop normally and healthy. So how do we solve this problem?
What is the most efficient light source for plants?
Many growers’ planting practices have proved that LED lights are the most efficient plant supplement light source today, so our following data are based on LED lights.
Why is indoor planting so popular?
Indoor planting is a very popular solution now, because you can control the growth environment in a timely manner according to the growth status of the crop. If appropriate measures are taken, this procedure can be as effective as the natural growth process. In addition, you don’t have to worry about the problem of light (the indoor environment is without sunlight), because we have an excellent option to replace sunlight to provide light supplementation to plants-grow light.
What color light do grow lights emit?
Many manufacturers claim that their grow lights are “full spectrum” color, which means that the light they emit includes not only blue and/or red light, but also enough green light to make the overall output look more like natural light. The human eye is also receptive to this light and color. Although blue and red light are the most important light colors for plant growth, studies have shown that certain species grow best under full-spectrum light, so choosing full-spectrum light will help.
What type of light bulbs are used in a home?
The most common types of lighting include LED and fluorescent bul bs, but you may see incandescent and high-pressure sodium bulbs when shopping around. There are pros and cons to using each type, and all can be found at local hardware stores or online.
How to keep plants healthy?
But even with LED and fluorescent lights, maintaining a proper distance helps to ensure healthy plant growth.
What is an understory plant?
In their native growing environments, these plants are “understory plants” meaning they grow underneath the branches of larger plants. Low lighting is not sufficient for starting seeds indoors. In environments with less light, plants grow more slowly and use less water. Avoid overwatering by feeling the soil.
What plants grow well in fluorescent light?
Medium-light plants. Medium- and low-light plants like this pink Begonia and two Chinese evergreens ( Aglaonema) grow well in fluorescent-lit places like an office lobby. These plants grow well indoors in areas that are well-lit such as in east-facing windows or near a west-facing window, but out of direct sunlight.
Why do plants need energy?
Plants 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.
How to choose plants for indoors?
Then choose plants with light requirements that match your indoor environment.
What does it mean when a plant's stems are leggy?
Plant stems become “leggy,” meaning stems become long and thin and appear to be reaching toward the source of light.
How does wattage affect plants?
A watt is a measure of energy consumption and really has nothing to do with how much light your plants will actually receive. As it turns out, LED lights consume much less energy than traditional bulbs which means, for example, that an LED light that consumes between 6W and 10W of energy can actually produce the same amount of light as a 50W halogen or florescent light might do. This is because it can produce the same amount of lumens at a much lower level of energy consumption. If you’re going to have a successful grow operation it’s important to move away from looking at watts and instead look at how many lumens the light you’re using produces.
How do LED lights help plants grow?
You want to make sure that your LED lights give off enough lumens to spark the photosynthesis process to ensure that your plants have a healthy growth cycle and produce crops at the end of that cycle that you can either sell or use for your family.

There may be no ideal amount, but, generally, if you can produce somewhere between 300 and 800 lumens per square foot your plants should prosper quite nicely.
How much energy does an LED bulb use?
As it turns out, LED lights consume much less energy than traditional bulbs which means, for example, that an LED light that consumes between 6W and 10W of energy can actually produce the same amount of light as a 50W halogen or florescent light might do.
What is lumen in plants?
In pure scientific terms a lumen is the amount of light emitted per second from any particular light source. Sounds very simple right? As it turns out the process pretty much is that simple, but think of it in terms of how it affects your plants. For plant growth there is an optimal amount of exposure to lumens that will result in the healthy plants you’re looking for, and that’s really our main concern. You want to make sure that your LED lights give off enough lumens to spark the photosynthesis process to ensure that your plants have a healthy growth cycle and produce crops at the end of that cycle that you can either sell or use for your family.

How many lumens does a 1000 watt bulb have?
Most commonly, plant leaves handle photosynthesis efficiently in 3000-4000 lumens per square foot. A 1000-watt grow light has an output of around 100,000 lumens. Considering a plant needs 4000 lumens for optimal photosynthesis, this means a 1000-watt bulb will have optimal coverage of 25 square feet.
How many lumens does a CFL bulb produce?
In every square foot, CFL, the compact fluorescent bulb produces at least 7,000 to 7,500 lume ns. Minimum light requirements on any plant should be 2000 lumens per square foot and approximately 5000 lumens per square foot on mid-range.
What is the difference between watts and lumens?
Watt is a measure of energy consumption. It does not determine the amount of light a plant receives. Traditional bulbs consume more energy than modern LEDs; thus, they have more watts while LEDs have fewer watts. Lumen, however, is a measure of the bulbs’ brightness. It determines the amount of light a plant will receive.
What temperature is needed for photosynthesis?
Optimal photosynthesis occurs in 68 degrees F to around 74 degrees F. Temperature above 80 degrees F slows down the photosynthesis process.
What is the measurement of lumens?
A high number of lumens indicate more intense light from the lighting source. A lumen is measured using a lux or simply a square meter. Using British measurements, one lumen per square foot is equivalent to a foot candle.
How many square feet does a 1000 watt bulb cover?
When purchasing grow lights, you should consider lumens. Bulb manufacturers and garden shops will woo you to believe a 1000-watt bulb can cover between 40-50 square feet. However, it’s worth noting that most consider actual light coverage but not based on plants’ photosynthetic processes.
