Grow Lights For Indoor Plants And Hydroponic Gardens


Indoor Grow Lights are a necessity when it comes to indoor gardening. You can enjoy a hearty and bountiful garden indoors year-round. All you have to do is make your plants think they are outdoors and the plants will act as if they are growing outdoors.

The correct grow lights will allow you to provide the proper intensity and hue that nature provides and the plants need in order to grow. Indoor vegetables, fruits, flowering plants, and herbs can all be cultivated from seed to bud indoors with a bit of an understanding of plant lighting.

3 Types Of Plant Grow Lights – HID (High-Intensity Discharge), High-Pressure Sodium (HPS) Metal Halide (MH) Fluorescent, and LED Grow lights (Light Emitting Diode)

Metal Halide grow lights are in the category called HID (High-Intensity Discharge) and gives off a hue that is in the blue spectrum. It’s the most effective color for plants in their early stages of root growth. Metal Halide mimics the light that the sun in our atmosphere gives off in the springtime. Metal Halide bulbs have an effective life of about 12,000 hours of burn time.

High-Pressure Sodium (HPS) is also a type of HID that is very popular for growing indoor plants. HPS lights give off light color that is in the red-orange spectrum and great for flowering plants. The red spectrum that an HPS bulb emits, mimics the atmosphere color at end of summer when the days get shorter and the sun sits lower in the sky giving off a red hue forcing plants to put all their energy into flower production.  It is common for growers to use both metal halide and high-pressure sodium set-ups in their grow room. When using only one light, you would typically choose the HPS as your all-purpose grow light.

Fluorescent Grow Lights is a low-cost plant lighting option. They have superior energy efficiency and a low purchase price for the amount of light they give off. Although these are weaker lights than all the other lights mentioned here, they are great for smaller plants and seedlings in their early stages of life.  Fluorescent light bulbs come in different hues. The “cool white” bulbs or sometimes called “daylight ” give off a more blue spectrum of light. These are better for plant seedlings and the early stages of growth. The “warm white” bulbs give off a more red-orange color of light. These two different light colors are achieved by the different types of coatings that are used inside the bulb. It is wise to use both types of bulbs at the same time, or a full spectrum bulb to cover the entire spectrum of the usable light that indoor plants require. The most common fluorescent light is the 4-foot fluorescent light which are found in many offices and schools. Another popular type of fluorescent bulb is the compact fluorescent light (CFL) bulb which are sold as energy saver bulbs and used in many homes to cut energy costs. CFL lights are being found in more indoor gardens and grow rooms due to the leaps in technology that has allowed compact fluorescentlight bulbs to emit more light, using less energy and at lower cost.

LED Grow Lights are used to only be found in electronic displays, but now are used in flashlights, decorative lights, landscape lighting, and now for indoor gardening. LED Grow Lights are super efficient and produce practically no heat. This lighting is great for indoor grow spaces that are too small to handle the heat that HID plant lights give off. You can  purchased LEDs in a variety of colors, however for plant light requirements, the red and blue bulbs are the most common. For this reason it is widely believed that LED lights give off more usable light. An LED light can last up to 70,000 hours or over 8 years compared to fluorescent grow lights that are effective for 8,000 hours or almost a year. Even though the upfront acquisition cost of these lights are higher than fluorescent, the energy efficiency and bulb lifespan make LED lighting the most inexpensive grow lights to use.

Choosing The Best Light For Growing Plants Indoors
Choosing the right grow light is an important piece of the indoor garden puzzle. There is no one true answer for knowing which grow light is best. The best grow light is the light that works best for your grow area and type of plant you are growing.  It is wise to first figure out which plants you will be growing, then determine how much and what type of light should be used. Growing plants, flowers and big buds indoors is fun and rewarding. With a little bit of research any plant that grows outdoors can thrive indoors under the right conditions. Just remember to provide the atmosphere that your specific plants get in their natural habitat.
