Which led lights for growing weed

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.

This superior energy-efficiency doesn’t come at the cost of light intensity since the Advanced Platinum LED light also boasts of having one of the highest PAR (Photosynthetic Active Radiation) on the market. It’s also broad-spectrum (since it’s LED) which means less work for you.

The Apollo metal halide grow light is rated 400Watts and has 4,200 kelvins. This makes this the perfect light for the vegetative growth stage of photoperiod plants (but not relevant for growers of autoflowers). This light is best suited for those growing a larger number of plants. This is because it is a bit demanding to install and use since it doesn’t come with the standard E26 base. It uses an E39 stand instead, so, you’ll need to install a separate ballast.

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.

7. The Vivavolt T5 Fluorescent Grow Light

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.

Regular incandescent bulbs give off more yellow and orange light, starving leafy plants while they burn them.

This fluorescent light is very similar to the fluorescent lights you find in people’s homes. However, the Vivavolt T5 also provides the wide spectrum that photoperiod marijuana needs to grow indoors.

Kelvins

The fluorescent light tubes are also two feet long, so the four 24W tubes each provide double the amount of light that you can get from ordinary lights. The T5 is suspended from two points, making it easy to install or adjust relative to the size of your plants. This light system works very well for larger gardens because of how much space a single light can cover.

Can I leave my grow light on 24 hours?

Which led lights for growing weed

Most of these “new to horticulture” LED manufacturers are making claims that you should be using a full spectrum LED in flower to truly maximize plant terpenes and THC levels. But is this really true? See the graph below comparing what parts of the light spectrum is used for photosynthesis compared to the full spectrum light from the sun.

For this reason alone, this research should be thrown out.

Unpacking Existing Information

When comparing both technologies, always compare light levels of the entire grow and not just fixture to fixture. I cannot stress enough that there is no such thing as a 1-for-1 replacement of HPS by LED! That simply does not exist in the marketplace. Yes, there are LED fixtures that exist when measured directly beneath the fixture. The output looks equal to or even greater than an HPS. But, when you move the PAR sensor any direction from centered beneath the LED the light level decreases much more under the LED than any HPS fixture!

One of the crucial elements a cannabis plant needs is light. During photosynthesis, a plant converts light energy into chemical energy, allowing it to grow strong and healthy, and with cannabis in particular, light also fuels bud production.

Factors to consider before buying a grow light

There are many types of lights, but below are the four most common you’ll find in a grow room. There are many variations within each of these four types as well, and new lights and technology come out all the time.

Safety

Some grow lights are more expensive than others, but also more efficient, saving money in the long run. Some lights are bulky with many parts, some light in weight, and some are better suited for young or mature plants.
