Which is the most suitable bonsai grow light for you?

There are many models on the market, each with its own build, functionality, and other features. To compare your options, we have provided a list of 4 main tips.

Output of Light

You should note the light intensity of the models you want to buy; this is measured as PAR (Photosynthetic Active Radiation). You can also check out PPFD (Photosynthetic Photon Flux Density) to see how much light is exerted on a surface. You can have adverse effects if the grow light does not maintain a steady current.

High-performance models have different brightness levels and colors that promote photosynthesis, so you can sustain your plants at any growth stage.

Timing Function

Let’s say you hate manual machines. If that’s the case, opt for a model that’s got integrated timing. Set this up, and the light will turn on and off based on your settings, so you won’t lose sight of what your bonsai trees need. With high-quality LEDs, you don’t have to worry about how long the grow light will be on. 

Approximately how long the bulbs will last

Every light source has this attribute; the bulbs produce light for an estimated time. The LEDs in grow lights allow them to retain their brightness for a more extended period than other bulbs. Depending on the quality of the light bulb, models can last from 20,000 to over 50,000 hours.

Frequently Asked Questions

To grow a bonsai tree, what kind of light is required?

Bonsai trees need direct sunlight or a spectrum of light that supports them. Incandescent lighting does not provide the spectrum of light required to grow plants.

How many hours of light do bonsai trees need?

You need about 5-6 hours of direct or indirect sun a day, depending on what species of bonsai you’re growing. Some species can burn when exposed to too much light.

What is the most efficient way to grow bonsai under a grow light?

Under the grow light, place bonsai trees in different positions to support growth at different stages. You should also regulate how much light the grow light generates to control how bright it is for the trees.
