What is the best light for plants?

Sunlight contains the complete spectrum of light including all colors of the rainbow: red through yellow to blue and violet. Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum.

Will 5000K LED grow plants?

The reason for this, is that at the “warm white” color temperature, the “ratio” of wavelengths is ideal for plants. … Go higher than 5000K, and so much red light is left out from the spectrum your plants will grow slowly and without much vigor.

Will blue LED grow plants?

Blue LED Lights Blue light is a specific light wavelength that is needed by plants for photosynthesis and growth and is ideal for use on seedlings and young plants. Blue LEDs are far more efficient than they were a few years ago and are useful in grow light systems in combination with other light wavelengths.

Is blue light bad for plants?

The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.

What lights do professional growers use?

Today, the most widely used lights for professional use are HIDs and fluorescents. Indoor flower and vegetable growers typically use high-pressure sodium (HPS/SON) and metal halide (MH) HID lights, but fluorescents and LEDs are replacing metal halides due to their efficiency and economy.

What to look for when buying grow lights?

Does blue light make plants grow faster?

This helps create the optimal growing conditions for the plants and saves on energy by getting the most usable light per watt. … Blue spectrum lighting during the vegetative cycle maximizes the efficiency of photosynthesis for healthy and strong plant growth.

How far should LED grow lights be from plants?

16-36 inchesFor established plants, they are already where they need to be in order to thrive. During the flowering stage LED Grow lights should be located between 16-36 inches from the plant canopy. Moving the grow light closer will increase the light intensity which can maximize photosynthesis.

What is the difference between red and blue LED grow lights?

Red/Blue LEDs This combination is more energy efficient than “white” or full spectrum LEDs because blue and red LEDs have the highest photon efficacy compared to other colors i.e. they convert the highest amount of electricity in photons, so you are getting more growth from your plants per dollar spent.

Are white LED lights good for plants?

White LED lights are also great lighting to help enjoy the plants as they grow, and they provide a 40% light absorption rate. Additionally, because they are LED, these lights will not burn or over chafe the leaves, ground or soil with a drying light.
