1700-2400 umol/s per 5’x5’+ area.

LED grow lights are available in different forms, so let’s look at the pros and cons of each so you can find the right LED light for you:

How many watts does the fixture draw from the wall? To determine this, view the fixture specifications. Be aware that the number in the title or name of the light likely doesn’t represent actual wattage. It may be a model number, total LED wattage, or an HPS wattage equivalent.

Is the spectrum sufficient for your plant’s growth stage?

What brand of driver(s) power the LEDs? Mean Well and Inventronics make high-quality drivers but there are other good ones too. Low-quality drivers in most budget lights fail quickly.

The HLG 600 Rspec features a slightly larger heatsink with a 600W driver which provides 18% more output for more coverage and bigger yields, compared to the HLG 550 Rspec.

Is there a PAR map available of the fixture? Are the PPFD readings sufficient for your stage of growing? How uniform are the readings across the footprint (spotlight vs even footprint)?

A proper, well constructed LED grow light will have a uniform spectrum. So if you have 4 plants under your light, they all get the same spectrum.

An LED grow light bulb is exactly what it sounds like – a single LED bulb. Similar to LED bars, you wouldn’t usually use one of these to grow plants through flower.

You typically wouldn’t use an LED bar to grow a plant from seed to harvest. Instead, think of these as supplemental lighting to a main light source (maybe HID).

HIDs require a reflector and ballast, LED grow lights do not. They can last for decades, whereas HID bulbs will often need to be replaced every couple of years. But, one of the main reasons LED grow lights are regarded as the best is due to the spectrum they produce.

Pros :

Cons :

LEDs are regarded as some of the best indoor grow lights on the market. But there are so many out there it can be tough to weed out the cheap, unreliable brands and models from the quality ones. And with the high price of some grow lights, it’s crucial that you do your research before purchasing.

Pros :

Higher quality diodes last longer and are more efficient (more light/watt). CREE, Samsung, Osram, Lumiled, and Bridgelux are brands that are commonly used high-quality chips. Epistar and Epiled are mid to low-quality chips, in comparison. That is not to say that some high-end LED grow lights don’t still use them successfully.

The Model-H is designed specifically for high PPFD cultivation practices in vertical farming. Full Spectrum design covers each critical phase of growth from vegetative to flowering. The spectral tuning capability allows growers to experiment with spectrum recipes. Hailed as the most efficient and highest yielding LED grow light on the market.

Pros :

The light system is highly efficient, and Black Dog states that it outperforms 600 watt high power sodium lights while using far less energy. It also directs more light to the flowers and leaves, instead of the stems of the plant, according to the company.

The Platinum LED P300 is an affordable, efficient, and powerful indoor cannabis LED grow light that produces the same light of a 400 watt high power sodium light, while only consuming 180 watts of power, according to the company.

This can vary widely from one brand to the next though, so your best bet may be to follow the manufacturer’s recommendations on whichever light you purchase. Alternatively you can download a Lux Meter on your phone to provide a more accurate reading to understand the output of your light, allowing you to adjust the height for optimal growth.

Cannabis plants have two distinct growing phases – vegetative and flowering. When growing cannabis outdoors, the plants usually begin flowering (producing buds) when the days become shorter as summer shifts to autumn. Indoors, there are no seasons, so growers can “trigger” the flowering stage by artificially mimicking the seasonal shift by adjusting the hours of light the plants receive per day.

Platinum states the light provides a blend of 12 different bands of light spectrum and integrated 90 degree secondary focusing lenses to help the light penetrate deep into the canopy. The lights also have separate spectrums for the vegetagive and flowering stages.

HID lights include metal halide (MH) and high-pressure sodium (HPS) lights, and HID grow systems often use a combination of the two in order to increase yields. These lights tend to produce more heat and require more energy than LED lights. This means you may need more height in your grow space to keep the lights further from the plants.

The lights also appear white to the human eye, making it easier to assess plant health. The light system is one of the smaller made by the company, but can still cover more than 16 square feet of space in the flowering stage, and 27 square feet in the vegetative phase. The company also produces the smaller PhytoMAX-2 200 for growers looking for the ideal solution for growing one single plant.

Cannabis needs light to grow, and unless you live somewhere with a perfectly sunny, Mediterranean climate, you’re probably better off growing cannabis indoors with artificial lights. The good news is – indoor lighting allows you to control exactly how many hours of light your plants receive each day – no matter what the weather is like outdoors. But should you go with an LED or an HID? And how exactly do you use grow lights for cannabis cultivation?

LED lights are typically more energy efficient and give off less heat. This can mean that they are more safe, but looks can also be deceiving. Because the lights don’t appear to be working as hard, it can be easy to underestimate the light your plants are receiving, potentially resulting in light burn. Also, they tend to have a higher price tag than HID lights.

Also, the kit comes with heavy duty hangers and a mechanical timing switch to help with setup and operation.

The Sun System 150 watt is a smart option for home growers who don’t have a huge budget and are only looking to grow a single plant from seed to harvest.

The kit comes with a wing reflector hood sect, heavy duty hangers and a 24-hour mechanical timer, as well as a digital dimmable electronic ballast to provide full control and maximize the lumens provided to the plants.

If in doubt, speak to the seed provider about the vergetative and flowering stages of the particular cannabis chemovar and when triggering is recommended.

There is no black and white answer to this question. LED lights allow more customization in the light spectrum meaning that they can be easily adjusted for the vegetative and flowering stages. They also produce less heat, are more energy efficient, and last longer. At the same time, they can cost significantly more – even to an extent that exceeds what you may save in energy costs and many LED lights are relatively new in the market while HID have been reliable go to for indoor growers since the 1990’s.

The team at Black Dog LED is known for producing top of the line LED lights for professionals and amateur growers, and the PhytoMAX-2 400 is the ideal size for an indoor grow of up to about 6 plants.

Lights produce a lot of heat, so you’ll want to make sure they aren’t too close to the tops of the plants, in order to keep from causing any damage. If you hold your hand under the lights at the level of the top of the plants and it feels too hot for you, you’ll want to raise them a bit. This also depends on the power of the light. For smaller, 150 watt lights, about a foot above the plant canopy should be enough, while with a 600 watt light you’ll want to hold it between one and two feet above the canopy.

The light system also has fully programmable spectrum control, though this requires purchasing the SolarSystem controller separately. The company also states that the light is especially easy to install and never needs bulbs.

At only $119.95, the iPower 400 watt digital grow system can produce an instagram-ready indoor cannabis grow at a fraction of the cost of many LED systems.
