Growing Peppers Indoors [Top 3 Grow Lights for Peppers]

    Is it possible for anyone to grow peppers inside a room? The answer to this is yes, definitely you can! If you are interested in growing pepper plants from seeds indoors, you will need a grow light to kick start the seeds to form the sprouts.

    Grow light is one of the best investments for those gardeners who are eager to grow pepper indoors.

    Peppers are full sun and high light plants, which means they need a minimum of 7 to 8 hours of sunlight every day.

    But now the real question is if you are growing pepper indoors, how much and what type of artificial light will they need?

    To know the answer to various questions related to growing light for harvesting peppers indoors, go through this article below. So with no further delay, let us begin!

    How much light do indoor peppers need?

    As mentioned above, pepper plants need more than 7 hours of direct sunlight every day to thrive and remain alive.

    However, this amount of sunlight is not enough for the plant to produce fruit. For that, you will need at least 16 hours of sunlight every day.

    You can give them as much natural light as possible and then keep them for the remaining hours under the grow light.

    However, pepper plants can also breed under a grow light on full-time lighting. You can put a timer on the lights, so you do not have to remember to turn them on and off.

    Can you grow peppers with a grow light?

    Peppers are a type of fruiting plant. However, fruiting and heavy flowering plants like pepper need colored lights when they are entering their flowering phase.

    Red and yellow lights are necessary for the formation of flowers for red and yellow bell peppers.

    According to a study, it is observed that peppers nurture the highest number of flowers when most of them receive almost 95% of red light.

    Thus you will need a grow light with a high red spectrum. You can also implant blue spectrum grow light for good vegetative growth.

    So, if you are interested in growing peppers indoors, grow, or artificial lights are mandatory for their rapid growth.

    What kind of light do you need to grow peppers indoors?

    To grow peppers indoors, you will need the following type of light.

    1. Fluorescent Grow Light

    T5 and the compact Fluorescent Light or CFL are the two most popular fluorescent grow lights available in the market.

    CFL is a compact, twisty and distinct light and is one of the best cost-efficient alternatives if you are just a beginner.

    On the other hand, T5 are vertical tubes that are parallel to one another. These tubes are usually available in 2 and 4 feet of height.

    2. LED Grow Lights

    LED or Light Emitting diode is another famous light for growing peppers. It is free of mercury and energy-efficient as they create more light in comparison to fluorescent ones with the same amount of electricity.

    The light comes with a longer lifespan and needs low maintenance.

    3. HID or High-Intensity Discharge Grow Lights

    HID or High Intensity Grow Lights are the most advanced and expensive option when it is a question of growing peppers plants indoors.

    The light discharged by these lights is exceptionally high and includes double efficiency than the fluorescent lights. There are two varieties of HID lights which are:

    4. HPS or High-Pressure Sodium Lights

    HPS creates a late afternoon or early morning heat that delivers a more yellow, orange, and red spectrum. It is very efficient for helping flowers and fruits of pepper plants to bloom.

    5. MH or Metal Halide

    MH grow light emits mid-day scorching daylight that assists the pepper plants in nurturing their leaves.

    How long to leave grow lights on for Peppers?

    It is common among gardeners to place the pepper seedlings near the sunny windowsill for natural light absorption.

    However, this might seem enough for other plants, but this is not perfect for pepper. Since only natural sunlight is not enough for the growth of the young seedlings, they will need to grow lights.

    It is due to natural sunlight from the windowsill, helping the plant grow. But it will make them leggy and tall.

    Usually, it is always colder near the windowsill, making the plant weak and lowers the pepper yield in the future.

    Thus, to prevent this, you have to use grow lights for at least 12 hours every day while harvesting peppers indoors. You can keep it on for a maximum of 16 to 18 hours duration for rapid seedling growth.

    How far should grow lights be from Pepper plants?

    Generally, place the grow lights 2 to 4 inches away from the top of the plant. Place the LED grow lights at least 24 to 36 inches higher above the plant canopy.

    However, this is dependent on the power or wattage of the light sources. Thus the distance of the grow lights from the pepper plant is dependent on the type you will use.

    The incandescent bulb grows lights should be placed at least at a distance of 24 inches over the pepper plants.

    Fluorescent grow lights include a lower heat signature and need to be placed 6 to 12 inches over the pepper plant.

    Keep managing the grow light placement as the pepper plants mature and develop for maintaining a proper distance. So consult the specific type and model of the grow light for exact directions and specifications.

    What wattage grows light suitable for Peppers?

    One of the simplest ways to set up an artificial grow light for growing peppers inside your house is to remember a thumb rule.

    You will need 40 watts of grow lights for every square foot of the area for high-light demanding plants like pepper.

    For example, if you have a 4inchesX4 inches square foot area, you will require 600 watts of grow lights for harvesting high-yielding plants like pepper.

    Thus, the larger area you want to cultivate indoors, the more complex and costly the entire process will be.

    Guide to Select the Best Grow Lists for Peppers

    While selecting the best grow light, you have to keep the following factors in mind before making an ultimate decision.

    1. Color Temperature

    Color temperature is responsible for the light that appears from the grow light present in the visual spectrum. It is usually measured in Kelvin and ranges from 3000 to 6500K.

    But the lower the number, the redder shifted the light will appear. Color temperature is also related to the light wavelength, measured in a nanometer, and ranging from 400 to 700 nm.

    If you want to use a grow light for all-year pepper cultivation, go for the grow light, including 640 to 700 nm of red, white and 450 to 500 nm of blue LEDs. In this way, the user does not have to change the grow lights during various growth stages of the pepper plant.

    2. PPFD and PPF

    The grow lights include ratings like PPFD and PPF, which are Photosynthetic Photon Flux density and Photosynthetic Photon Flux, respectively.

    PPF is responsible for measuring photosynthetic active light that emits in every direction. This measurement only considers the lights in the wavelengths between 400 to 700 nm.

    PPFD measures the total amount of photosynthetic active light that will reach the surface.

    3. Coverage Area

    For knowing the accurate size of the grow light for harvesting pepper plants indoors, you have to know the total coverage area.

    Since you cannot place the seedlings not too far from the lights, measure the entire space before buying any artificial lighting.

    4. Set up of the lights

    The grow light is also dependent on the growing space and how many pepper plants the user is planning to harvest.

    There are many grow lights that come with hanging kits for the installation, while others with an attached stand. There are also other bulbs that you can fix into the bulb fixture.

    Thus, pick up the best grow light with the most suitable setup settings according to your space.

    5. Electromagnetic Spectrum

    The light, the electromagnetic spectrum, consists of blue, green, red, purple, yellow, and white. For growing and harvesting peppers, you will need a high spectrum light in the blue range.

    If you find it difficult to change the spectrum in every stage of plant growth, you can use a full spectrum while growing light which is perfect for all cultivation stages.

    Final Words:

    Indoor growing of pepper becomes exceptionally easy with growing lights. It allows the user to cultivate pepper plants during any time of the year and in weather conditions.

    Start the seedlings, nurture the plant, or pamper the plants with grow lights, particularly architecture for mimicking the natural light. These lights are economical and easy to use, and you will love harvesting your little pepper seedlings that flourish under their glow!
