Indoor growing can offer you a lot of interesting benefits, from pests control to weather/climate control.

By using LED lights for indoor gardening plants, you can provide your plants with the adequate lighting they'd need to effectively photosynthesize.

But how do you use the right type of grow lights with the spectrum your plants need to grow?

What are LED Grow Lights?

If you want your plants to effectively process photosynthesis and also grow well, then LED (Light Emitting Diode) grow lights might be the best option you could go for.

So what exactly are LED grow lights?

LED lights are the latest Techno in the market today; nothing like other traditional lights: fluorescent bulbs, incandescents, and the likes!

They do not make use of filaments, gas, lead (as in incandescents), or mercury (as in CFLs) like fluorescent lights.

They seem to last longer than these conventional lights and are more versatile and durable than fluorescent bulbs.

They do not have any fragile parts that are prone to some sort of failure in the long run comapred to fluorescent lights.

The LED lamps are made up of LED chips which efficiently provide your plants with the strong illumination they need to grow.

The LED chips are made using 2 separate semiconductors: holes (having the positive charge), and electrons (having the negative charge).

These chips can be quite effective in the production of quality light. They offer a combination of the light spectrum (the colors) and strong brightness your plants need to thrive in an artificial growing environment.

When power is applied and electric current begins to pass through, materials that make up the LED collide, in a process referred to as "combination", to release energy in the form of light quanta and photons.

LEDs are designed to replicate natural lights and provide your plants with a balanced light spectrum of red, green, and blue light.

LED lights can also provide the temperature and adequate light intensity that's similar to that from the sun.

And, unlike other types, the light from LEDs can be centered directly on your grow alone, to ensure that right amount light is used.

LEDs can also be remarkably energy-efficient. They do not seem to consume excessive power like other grow lights. They can still provide the brightness and spectrum of light similar to that your plants will naturally get from sunlight if grown outdoors or near your windows.

Grow Light Color Spectrum: Warm Vs. Cool Lights

There are different qualities of grow light and this makes it a lot more difficult for a grower to immediately make their decision without having to choose the wrong option for their plants.

Choosing either type can depend on three things;

  1. The particular type of plant you're growing,
  2. The particular stage you're in in the cultivation process, and
  3. The specific requirements (photoperiod) for your plants to fruit and blossom into maturity.

How to Choose a Grow Light for Indoor Gardening Plants

Using grow lights can be quite expensive. But, you'd actually start getting your money's worth on those seemingly expensive grow lights in the long run.

When they start fulfilling the purposes for which you had purchased them, especially when you get your first bountiful harvest, you'll then fully understand why you should actually need a grow light in the first place.

Step-by-step Instructions

Step 1: Hang your grow lights over your grow area at a relatively safe distance.

Step 2 : For sprouting your seeds, you can look up the growing instructions for the specific plant you're growing to determine how much light they need to grow properly.

For already sprouted plants, you can also check the necessary instructions for using the particular grow light you've purchased to be entirely sure.

The general standard for most growers is to hang their grow lights as high as 12 inches. This may, however, differ for you depending on the type of plant you're growing as well as the growing stage of the plant.

Step 3: Draw up a flexible schedule according to how long you have to feed your plants with the lights.

You don't want to feed them too much and too little. Giving more than enough light to your plants can stunt their growth and ultimately damage them.

Giving way less can also equally do the same. You can check for the standard schedules for growing specific plants indoors.

Step 4: Set up the timer of your grow light. Typically, a grow led light comes with timers that help growers to easily control the amount of light their plants get without having to turn the on/off switch.

So, set up a timer that'll help you in controlling the light intensity as well as the duration you want to leave it on for.

Step 5: You also have to continually reposition the lights as your plants want to grow higher and higher during the vegetative stage.

Step 6: Once you hang your lights, don't leave your plants to do the job on their own. They also need constant monitoring.

You have to constantly monitor them every now and then to ensure they are getting the spectrum they need to process or manufacture nutrients through photosynthesis.

Final Thoughts

Wouldn't you like to grow without having to worry about changes in climate, weather, and the invasion of pests and parasites?

With LED grow lights, it is still entirely possible to replicate all the outdoor conditions needed for growing your plants.

This particular type of grow lights offers so many benefits and helps you to save your energy, as well as your precious money at the same time.

So, if you haven't joined the amazing gang of indoor grow light users, now may be the time to enroll.

Frequently Asked Questions

Do LED grow lights work for indoor plants?

Yes. Full-spectrum LEDs supply the light plants need to grow indoors, run cool, and use less power than older grow lights.

What color light is best for growing plants?

Plants use the full spectrum, but blue light drives leafy growth and red light supports flowering and fruiting. A full-spectrum LED covers both.

How close should LED grow lights be to plants?

Usually 12 to 24 inches above the canopy, depending on wattage. Too close can scorch leaves and too far makes plants stretch, so adjust if you see either.
