  • Grow lights (four feet)

  • Sturdy shelves

  • Power strip

  • Shop lights (four feet)

  • Growing trays

  • Heat mats

  • Timer

  • Light bulbs

What Is a Grow Light

A grow light is an artificial indoor light source made from an electric lighting system to replicate natural sunlight. This light is essential in the growth and photosynthesis process of indoor plants. In doing so, you'll be able to grow healthy indoor plants.

The grow light is set up based on the color spectrum of natural sunlight. They try to replicate all the colors in the spectrum, ranging from red to violet, to create the same effect as natural sunlight. You'll need LED grow lights for your indoor home growth. 

Fluorescent bulbs grow lights are also good alternatives. However, commercial growers should consider additional and more advanced lighting options for their in-growth.

What Are the Types of Grow Lights?

There are several types of grow lights, which may make choosing one that suits you challenging. However, the four most common types are fluorescent, LED, HID, and incandescent.

Incandescent Grow Lights

You're most likely to walk into an incandescent grow light more often than any other grow light type. They are also more affordable than other options and locally available in stores. Despite their pros, this type of grow light produces much heat that may be unconducive for plants' life. They have a scorching effect on indoor plants. They also consume more power and have short durability.

Fluorescent Lights

Fluorescent grow lights are made from fluorescent tubes. They can also appear in the form of spiral bulb designs. They produce the right amount of heat which is conducive to indoor plant growth. These lights have lower power consumption and last longer than incandescent grow lights.

What's amazing about this type of grow light is that they produce the full spectrum. This feature makes it resourceful for flowering and vegetable plants. The only downside is a higher price of these grow lights.

LED Grow Light

The Light Emitting Diode grow lights are made from several tiny diodes, each emitting light. They are considered the more advanced grow lights because of their wavelength range. 

They also produce little to no heat, making them ideal for plant growth. LED lights are also energy-efficient, and you can customize them depending on the specific color needed for your plants. However, they are pricier than other options, making them unaffordable.

HID Grow Lights

High-Intensity Discharge lights are grow lights made with electrodes and bulbs. An electric current application causes a reaction with the gas, producing bright light. They are widely used by commercial and greenhouse growers. They produce more intense light ideal for large-scale growth. This grow light is the closest to the natural sun as it has a wide range of colors and grow light intensity.

HID grow lights exist in two categories; High-Pressure Sodium and Metal Halide. The High-Pressure Sodium produces yellow light while the Metal Halide produces blue light. The HID grow light may be better than LED grow lights.

What Light Color Do You Need?

With all colors having specific uses in the growth of your indoor plants, grow lights come in different colors. Below, we have discussed the various colors in the color spectrum and when to use them.

  • The cool spectrum includes violet, blue, and green. This color spectrum is essential in the plants' smell, test, and color. They range from four hundred to five hundred nanometers. The chlorophyll absorbs blue light to use in photosynthesis, thereby helping the plant make its own food.
  • The warm spectrum includes red, orange, and yellow colors. These colors are essential in growing strong plants, flowering plants, and the growth of more vegetation. The red color is the key player here. 

The red color still plays a role in germinating seeds indoors, while the yellow and orange come in handy in the overall plant growth. They range from five hundred and eighty to seven hundred nanometers.

  • The full-spectrum grow lights are the best as far as indoor plants are concerned. They are the closest to the natural sunlight, emitting all the colors for the best plant growth. Red and blue are the most important colors in the spectrum for plant growth. However, using these colors alone may weaken your plants and make them grow slowly.

The Proximity of the Grow Light to Your Plants

How far or near the grow light is to your plants is a key consideration when setting up the grow light. Keeping these lights too close or far from the plants may affect the quality of the plants and their growth rates.

First, you need to hang the grow lights above your plants. This arrangement ensures an even distribution of light to the plants. Putting the grow light at an angle will cause the plants to grow towards the direction of the light.

The amount of heat the grow light produces determines how far you place the light. For instance, put the grow light at least two feet from the plants if using an incandescent grow light. This feature is because this light produces a lot of heat which may scorch your plants. 

A separation distance of one foot is enough if using fluorescent grow light. However, LED lights can be as close as six inches to your plants because they do not produce heat.

What Plants Can You Grow Indoors Using Grow Lights?

There is a wide range of plant varieties you can grow indoors using grow lights. Among them are:

  • Indoor herb gardens - You can grow culinary, recreational, or medicinal herbs, including marijuana, indoors during the winter seasons. These herbs need more light to have dense foliage. The grow light provides the extra light needed for healthy growth.
  • Indoor vegetables - Grow lights are very effective in growing leafy and root vegetables. Vegetables like spinach, lettuce, and much more need ample light for healthy and fast growth, which the grow lights provide.
  • Indoor microgreens - These indoor plants are immature edible greens grown under a controlled light environment. These plants grow well under grow lights ensuring the right nutrients and flavor.
