Jungle — LED G6i 1700 LED Grow Light VS Gavita Pro 1700e Gen2 LED Grow Light
Need help choosing the best grow lights for plants?
With so many types of indoor garden lights available, knowing which one is right for your indoor plants can be a bit tough.
All plants need light to grow. They transform light into energy through photosynthesis. And how much light they need depends on the plant. Flowering plants and seedlings need higher intensity and several hours of light each day to really grow and thrive.
For an easy set-up, grow lights with stands offer an efficient lighting solution.
Regular household light bulbs — called incandescent lights — aren’t efficient for plants for two reasons. First, they don’t provide enough of the light spectrum that house plants need. Second, they give off heat which is not good for your plants and they waste a lot of energy. The LED grow light is a good choice.
Types of Grow Lights for Plants
Fluorescent lights are much more energy-efficient, stay cooler than incandescent bulbs, and offer the blue and red spectrums that will help your plants grow.
Compact fluorescent grow lights cost more than the traditional fluorescent grow light bulb or tube light, but are well worth it. Compact fluorescent lights use about half the electricity of incandescent bulbs and have a long life span, which saves you money.
Most compact fluorescent light fixtures include a reflective hood. This is the most practical way to make the most of your artificial light.
HID Grow Lights
High-intensity discharge (HID) grow lights outperform all other types, offering more lumens per watt.
HID lights include mercury vapor and metal halide bulbs. Mercury vapor lights were the first available on the market. However, they’ve become virtually obsolete because they don’t offer optimum light spectrum for house plant growth and are not nearly as energy-efficient as newer HIDs. To take their place, metal halide grow lights provide superior light — closely matching the spectrum of actual sunlight.
LED Grow Lights
Light-emitting diodes (LEDs) are a relative newcomer on the market. Their light output is low. However, LEDs use less electricity than other grow lights for plants and give off less heat. The advantage here is that these lights can be placed close to plants without harming them.
You can customize your light fixture to suit your plants, too. Combine red and blue LED lights to provide your plants with the spectrums they need for exceptional growth and flowering. LEDs are a little pricey, but they’ll last for years.
The Jungle LED grow light was designed to be efficient and easy to install right out of the box. The Jungle LED system retains an IP65 wet-location rating along with its corrosion resistance is designed to accommodate installation in your grow space with minimal limitations. An ideal and efficient tool for any hydroponic cultivation or home grow, the Jungle G6i 1700/645W advanced LED system was designed to be efficient and easy to install right out of the box.

The fixture is dimmable to 50% without any loss of efficiency using the Gavita E-Series LED Adapter and Gavita Master Controllers.
How Lighting is Measured
Before going through the various lighting types, it is good to see how light is measured, and what each bulb has to offer.
There are a few ways that light is measured, but some are almost obsolete, but still used in some things. Foot-candles or candle power is one such term, and this often relates to flashlights or spotlights that shine in millions or thousands of candle power.
Temperature is one of the primary terms you will see when growing in hydroponics and when looking for the ideal light. This temperature has nothing to do with heat output, but it is a reference to the natural color of the light produced.
When we see cool lights, these deliver light at the blue end of the spectrum while when we look at lights that are warmly looking, these are providing light at the orange/ red end of the spectrum.
Lights can be measured by watt power, nanometers (nm), or Lumens most often. The watt power is the unit of energy required to run the lighting, and it is the term most people are familiar with. When it comes to grow lights, these are often rated to the number of watts needed for each centimeter squared of the surface to be illuminated.
Lumens are a reflection of how bright a grow light is, and although used, these lumens are not actually a rating that does anything for the plants. The light required by plants is beyond the physically visible spectrum.
When light is measured in nanometers, this is actually the light we can see. This visible light falls in the range of 400 to 700 nm. When you compare this to the color spectrum, the warm or red end will be reading 730 nm, and at the other end in the color part of the spectrum (violet), this will be reading 400 nm.
Almost all grow lights fall in the range of 450 nm to 730 nm. These are the most crucial nm measures with one addition of 650 nm in the middle of the spectrum.
We all know that plants need to photosynthesize, and for plants to do this, there is the need for light at the 450 nm and 650 nm levels. With these, plants can create the food it requires from the light available along with water and carbon dioxide. It is the green pigment where chlorophyll is produced.
When plants use the 650 nm and 730 nm ranges, this allows them to control their flowering through another pigment which is called phytochrome.
This is why the full spectrum of light is required at varying stages of a plant's growth, and this is why it is crucial to have the best lights that allow growers to replicate this.
How Much Light Do Indoor Plants Need?
There are different requirements depending on whether you’re growing photoperiod feminized strains or auto-flowering strains, and we’ll discuss them accordingly.
If you’re growing a photoperiod feminized strain, you’ll need to change your light schedule based on the phase of development.
During the vegetative stage, they’ll need anywhere from 16–20 hours of light per day. The short nights tell your plant that it needs to spend its energy on getting tall and spreading its leaves, allowing it to efficiently gather energy later on.
Then, when it’s time for them to begin the flowering stage, you should shift their schedule so they receive just 12 hours of sunlight per day. Noticing the longer night (mimicking the change of seasons), the plant takes the signal to shift energy from developing foliage and branches to sprouting buds.
If you’re growing an autoflowering strain, however, light schedules are a different (and much simpler) story.
See, their name comes from the fact that they don’t rely on light signals to start flowering (unlike photoperiod varieties). Rather, it happens automatically after a few weeks into the vegetative process! Considering that, many growers will leave their autoflowers under the light for 24 hours a day, never turning their lamps off.
However, others argue this is too much for them, and will instead give 18–22 hours of daily light. They do this because plants can get a fair amount of their growing done when they stop taking in energy. Turning off the lights, of course, stops that taking-in process and signals them to focus on growth. This way, plants have enough light to develop impressive results, without your energy bill spiking from constant use.
Don’t Forget to Adjust Your Grow Light
Before we let you go, we want to emphasize again that photoperiod plants will only thrive if they’re on the right light schedule for the vegetative and flowering stages. To assist in that effort, many LED light manufacturers will include a dial, switch, etc. that allows you to switch between modes for each stage.
Along with making that switch, be careful to ensure that you’re raising your lights up in proportion to the vertical height of your plants. The lamps may not generate much heat, but you still want to avoid the risk of burning them.
As you can see, not all grow lights are created the same. Each comes with its own benefits, and also its own unique downsides.
On top of this, is the fact that all grow rooms are very different, so there are countless other variables growers need to consider. Lighting is only one part of this puzzle, but it is evident, no one lighting system is perfect.
Growers need to understand all of their plant’s requirements, and also what they want from their plants. When they know this, they can put things in place, and choose the best lighting system that their budget allows. Even then the choice may not be so simple, but at least growers will know the options they have, and which lighting systems are most suitable for them.
