How Do I Know Which Grow Light to Buy?

by TUBU

February 29, 2024


A grow light is an artificial light source specifically designed to promote plant growth. It can make up for the problem of insufficient natural light or insufficient light time, helping plants grow healthily indoors or in environments with insufficient light. Grow lights are an effective plant lighting tool that can help you grow healthy and beautiful plants indoors or in low-light environments.

How to Buy the Right Grow Light

The size of your grow space

Small spaces (up to 3 ft²): Look for compact lights like LED bulbs or small LED panels. These are efficient and affordable for small herb gardens or seedlings.

Medium spaces (3-10 ft²): LED grow bars or small quantum boards are suitable for these spaces. They provide more coverage and intensity than bulbs or small panels.

Large spaces (over 10 ft²): Larger quantum boards or even light movers are ideal for bigger gardens or commercial setups. These offer superior coverage and light intensity for efficient plant growth.

The type of plants you are growing

Leafy greens and herbs: These generally thrive under cooler color temperatures (around 6500K) with a good balance of blue and red light.

Fruits and flowers: These often benefit from warmer color temperatures (around 3000K) with more red light spectrum to promote flowering and fruiting.

Your budget

Growing lights range in price from affordable options like bulbs and small panels to powerful and feature-rich quantum boards. Determine your budget and prioritize features like adjustability, spectrum control, and smart functionalities based on your needs.

Things to note when buying grow light

Look for lights with a full spectrum: This ensures your plants receive all the necessary wavelengths of light for healthy growth.

Consider the PAR (Photosynthetic Active Radiation) value: This indicates the amount of usable light for photosynthesis. Higher PAR generally means better growth potential.

Check the lumen output: This measures the total amount of light emitted. However, PAR is a more relevant metric for plant growth compared to lumens.

Choose lights with adjustable intensity: This allows you to tailor the light level to the specific needs of your plants at different stages of growth.

Read reviews and compare features: Research different brands and models to find a light that meets your specific requirements and budget.

Remember, consulting with experienced growers or professionals at reputable grow light stores can also be helpful in making an informed decision. Contact TUBU.

Grow Light Five FAQs About Technology

What is photosynthetic photon flux density (PPFD) and how does it affect plant growth?

Photosynthetic Photon Flux Density (PPFD) is the number of photons per unit of time reaching the surface of a plant leaf in μmol/m²/s. It is an important measure of the effectiveness of a grow light.

PPFD has a significant impact on plant growth. Insufficient light will lead to slow growth, yellow leaves, poor flowering and fruiting. Too much light will lead to reduced photosynthetic efficiency, leaf burn and other problems.

In general, different plants have different needs for PPFD. Light-loving plants such as vegetables and fruits need higher PPFD, while shade-tolerant plants such as foliage plants and succulents need lower PPFD.

How does the spectrum of an LED grow light affect plant growth?

Spectrum refers to the relative intensity distribution of different wavelengths of light in a ray of light. Different wavelengths of light have different effects on plant growth.

The spectrum required for plant growth is mainly concentrated between 400nm and 700nm, of which the blue light from 400nm to 500nm and the red light from 600nm to 700nm are the most important for plant photosynthesis.

Blue light can promote the growth of plant stems and leaves, making plants stronger. Red light can promote plant bud differentiation and fruit ripening.

LED grow lights can adjust the spectrum to meet the needs of different plants. For example, it can provide high PPFD red and blue spectrum for light-loving plants and low PPFD red and blue spectrum for shade-tolerant plants.

What is the lifespan of LED grow lights?

LED grow lights typically have a lifespan of 50,000 hours or more. This means that if used 12 hours a day, LED grow lights can last over 10 years.

The lifespan of an LED grow light depends largely on the quality of the LED beads. Higher quality LED beads will provide a longer life.

Do LED grow lights make noise?

LED grow lights generally do not produce noise.

Traditional plant grow lights, such as high pressure sodium and metal halide lamps, produce more noise. This is because these lamps require a ballast to start and stabilize the light.

LED grow lights, on the other hand, do not require the use of a ballast and therefore do not produce noise.

Do LED grow lights emit radiation?

LED grow lights produce a small amount of radiation, but this radiation is not harmful to human health.

The radiation produced by LED grow lights is mainly concentrated in the ultraviolet (UV) and infrared (IR) wavelengths.

UV rays promote plant growth, but excessive UV rays can be harmful to plants. Infrared light provides heat to plants, but too much IR can cause plants to become too hot.

High-quality LED grow lights use filters to minimize UV and IR radiation.
