Having some peaceful greens to look at can really brighten up your home. But what would you do if you live in a suburb without a garden space? Although there are quite a few ways to liven up your indoor space with a bunch of greens, one of the best ways is to grow your own plants with a grow light bulb. This bulb is a specially designed light bulb that helps plants grow indoors by providing the right amount of light that they need to photosynthesize. By using a grow light bulb, you can grow just about any type of plant indoors, regardless of the season or weather outside.
Although a relatively new innovation, the market has quickly been flooded with all sorts of grow light bulbs to choose from. In this article, we’ve compiled a list of some of the highest-rated grow light bulbs of 2023 and will ensure that by the time you’re done reading, you’ll know exactly what you need to look for when shopping around.
Although your options have been cut down by a lot, we still need to walk you through what you need to consider to ensure you make the best decision according to your grow light needs. Below is a buying guide with everything you need to consider before finalizing your purchase.
What Is a Grow Light Bulb?
A grow light bulb is a specially designed light bulb that simulates sunlight to help indoor plants grow. These bulbs come in various shapes, sizes, and colors, and each type is designed to provide different light intensity levels and spectrum.
What Are the Different Types of Grow Light Bulbs?
There are three main types of grow light bulbs: fluorescent, HID (high-intensity discharge) and LED (light-emitting diode). Each type has its own advantages and disadvantages, so here’s a little breakdown.
Fluorescent grow light bulbs
Fluorescent grow light bulbs are extremely common as they’re relatively inexpensive, easy to find and come in various shapes and sizes. Most importantly, they emit a soft, diffused light ideal for seedlings and young plants.
The main downside of these bulbs is that they don’t produce as much light as HID or LED bulbs. They must also be replaced more frequently, typically every six months to a year.
HID grow light bulbs
HID grow light bulbs are considerably more powerful than their counterparts. They emit a bright, intense light that helps large plants and flowers. HID bulbs also last longer than fluorescent bulbs.
The downside of HID bulbs is that they’re more expensive than other types of grow light bulbs. They also produce a lot of heat, so you’ll need to use a fan or ventilation system to keep your plants from getting too hot.
LED grow light bulbs
LED grow light bulbs are the newest type of grow light bulb on the market. They’re more energy-efficient than other types and last longer. LED bulbs also produce very little heat, so you don’t need to worry about ventilation with these bulbs.
The downside of these bulbs is that they’re more expensive than other types of grow light bulbs. They also don’t produce as much light as HID bulbs, so they’re not ideal for large plants or flowers.
Uses of Grow Light Bulbs
Starting seedlings: Grow light bulbs are ideal for starting seedlings because they emit a soft, diffused light that won’t damage delicate plants.
Growing plants indoors: If you don’t have access to natural sunlight, grow light bulbs can provide the light your plants need to grow.
Extending the growing season: Grow light bulbs can be used to extend the growing season by providing extra light to plants in the winter months.
How To Buy a Grow Bulb
The purpose of a grow bulb is to provide the light that will help plants grow; for that, they need to generate a particular color temperature. The ideal temperature is between 5,000 and 6,500 Kelvin. This color temperature can be found in both cool white and daylight bulbs. When picking a grow bulb, pay special attention to the color temperature listed on the packaging, as it will dictate whether the bulb is best suited for vegetative growth or flowering.
Lumens measure the amount of light that is emitted by a grow bulb. When it comes to growing plants, you want a grow bulb with a high lumen output. This means that more light will be able to reach your plants, which will promote growth. Look for grow bulbs with an output of at least 3,000 lumens.
The wattage of a grow bulb measures how much energy it uses. As you might expect, higher-wattage bulbs will use more energy than lower-wattage bulbs. They will, however, also produce more light. When choosing a grow bulb, look for one with a wattage that is appropriate for your needs. A lower wattage bulb will suffice if you are only growing a few plants.
Lifespan is another critical consideration when choosing a grow bulb. You want a bulb that will last for several growing seasons, so you don’t have to keep replacing it. Look for grow bulbs with a lifespan of at least 10,000 hours, as they will provide you with the most value for your money.
Some bulbs produce more heat than others, and this can be a problem if you are growing plants in a small space. If you are worried about heat buildup, look for bulbs that are labeled as “cool burning.” These bulbs will produce less heat, making them safer for use in enclosed spaces.
Not many people are aware of this, but the color of light that a grow bulb emits can actually have an effect on plant growth. For example, blue light promotes vegetative growth, while red light is better for flowering. If you want to encourage growth in a particular area, look for grow bulbs that emit the color of light you need.
When growing plants indoors, choosing a grow bulb that is safe to use is important. Some grow bulbs emit high levels of ultraviolet (UV) light, which can harm your skin and eyes. If you use a grow bulb that emits UV light, wear protective clothing and accessories, such as gloves, goggles, and a long-sleeved shirt.
In addition to UV light, some grow bulbs emit high infrared (IR) light levels. While IR light is not harmful to your skin, it can harm your eyes. If you are using a grow bulb that emits IR light, make sure to wear protective goggles.
Finally, it is important to note that some bulbs produce a large amount of heat. If you use a grow bulb with a lot of heat, keep it away from your skin and any flammable materials.
