How do you choose the right plant growth light to put in your garden?

If you grow vegetables, herbs, flowers, or fruits indoors, please be aware that they need enough light and are suitable for the plants themselves. This is also to promote their growth and healthy growth. It can also make you gain unexpected gains.


How do you choose the right plant growth light to put in your garden?


Growth light water culture planting


Due to the current planting mode development, indoor planting of growth lamps has become a reality.

There are many growth lamps on the market. With the help of these growth lights, the growth cycle of indoor plants is shorter, and the growth of plants is more uniform and tall. The knot is fuller.

Because plants need light for photosynthesis, and photosynthesis converts energy into sugar for plant growth, but for different plants, the required light is also different.


If you want to grow plants for flowering, low-light indoor plants are suitable because they rarely need supplemental lighting.


But seedlings and agricultural products grown indoors require a lot of bright light to grow and bear fruit. Based on the plants you grow, make sure to choose the best lights for your home and plants.


Plant growth lights used by professionals


There are many plant growth lights on the market, among which high-intensity discharge (HID) plant growth lights are one them. Although these can be installed anywhere in your spare room, garage or basement, they require special fixtures.


There are two types of HID lamps: the first type is a metal halide (MH), and the second type is high-pressure sodium lights (HPS). The blue light produced by the MH bulb can promote the compact and leafy growth of plants. The red light waves emitted by the HPS bulb in the spectrum make plants bloom and bear fruit faster.


The price of HID is rising rapidly, and the most common one also costs $400. Because home gardeners usually only need a few weeks or months of planting lights a year, HID lights may be a bit too expensive to use at home. And HID has no advantage at present.


Should you choose LED lights or fluorescent lights?


Both LEDs and fluorescent lamps can produce the full spectrum of light needed for plant growth.

Many plant light kits contain LED or fluorescent bulbs on the market, but LED systems to have many advantages and are unmatched by HID lights, so more people will choose LED to grow lights.

First of all, although LED bulbs are more expensive than fluorescent lights at the time of purchase, they use half of the power required by fluorescent lamps and have a service life of 5 times that of ordinary fluorescent lamps.

The minimum service life of LED growth lamps is greater than 50,000 hours. They also emit less heat, reducing the cost of external heat-reducing equipment, and the mercury-free LED tubes will not be broken like glass fluorescent tubes, thereby reducing the safety hazards and LED lights in the landfill.

Management, environmental protection, and energy-saving.


Lighting plan


Plants will grow better with the help of full-spectrum light, which not only can provide full-spectrum light but also emit red and blue UV and IR light. 

Special LED grow lights and fluorescent "plant grow lights" will work, but cheaper fluorescent tube bulbs will also work. 

Make sure that the light source is within 6 inches of the plant leaves for best results.

For ease of movement, hang the fixture on a chain or place your plant on a table or tray. In order to keep your light working efficiently, please gently wipe the lamp tube to remove dust and dirt before using it every year to prevent dust and dirt from affecting the light irradiation and the heat dissipation of the light body.


Lighting plan for flowering plants


Red light waves are essential for stimulating plants to bloom and bear fruit indoors. Purchase LED bulbs and fixtures specially designed for plant growth. They are usually labeled as "growth lights" because they can generate a lot of red light waves.


Some electronics brands produce plant-friendly LED bulbs called "high-output LEDs."

The brightness of high-output LEDs is usually twice that of standard LED grow lights.

These super bright lights are very suitable for plants that grow in full sunlight and dry climates.

The plan is to light the flowering and fruiting plants for 16 hours a day. It cannot be lighted all day because the plants also need to ‘sleep’. 

Place the light source about 12 inches from the leaves of the plant.


How many lights do you need?


Once you have decided what kind of plant growth light you want, it is time to decide how much light you need for the space you have.

First, determine how much space needs to be illuminated. Then calculate the irradiation range and intensity of each plant light.

There are many LED plant growth lights on the market, with different sizes and powers.

The number of lights required is calculated based on the size of the lights you buy.

At present, a CT 640w LED grow light is suitable for 4ft*4ft and 5ft*5ft growth space, and so on, you can calculate how many lights are needed.
