What type of light is best for growing plants indoors?

The Sun System light emitting ceramic (LEC) is included in our top 10 lights for growing weed indoors because of its solid reputation. It’s been around for a quite a while, and there still aren’t many (if any) negatives to say about it.

This light has stood the test of time for more than eight years, so you can be certain that your money will be well spent.

Wattage also helps determine how far away you should keep your plants. Generally speaking, higher wattage lights need to be positioned further away from your plants because they can burn them. LED lights are an exception to this rule because they give off surprisingly less heat when compared to the other types of lighting with the same wattage.

As an LED, the 440Watt California Lightworks Solarstorm will work for your plants’ entire lifecycle. The light provides five bands of high PAR (Photosynthetic Active Radiation) from the deepest blue colors to the deepest red colors of light – a rich blend of everything your marijuana plants need.

As a general rule, however, CFLs produce the least amount of light, so these lights are best used for germinating or producing clones.

The downsides of this light are that it is rather noisy and doesn’t include dimming options. However, it still deserves a spot on our top 10 list.


Lumens is a measure of how much light a given light source emits during each second the light is on. Like the light spectrum, lumens are more relevant for photoperiod plants. “Regular” cannabis plants require varying amounts of lumens during the different stages of growth. For example, they need between 2,500 and 5,000 lumens per square foot in the vegetative phase, but it jumps to 10,000 lumens per square foot during the flowering phase.

Vivavolt T5 lights also cost less than LEDs, but LEDs last significantly longer.

What is the average cost of indoor grow lights?

Some plants, such as microgreens, may flourish under basic desk lamps, according to Zartarian. But cannabis plants need brighter and more consistent light to carry them into maturity. At the same time, cannabis plants need a so-called “dark period” during the flowering stage, but ample light is key throughout most of the marijuana plant life cycle.
