The coronavirus pandemic has disrupted the traditional food and agriculture supply chain in the US. It has been the major worry for many, especially when it comes to food. But thankfully, there is indoor farming. Indoor farming has been growing steadily for several years now, giving farmers a more food sustainability while eating fresh and healthy food.
Growing plants, specifically vegetables, and herbs, indoors is one way to increase food sustainability, especially in this uncertain time. Since it is indoor gardening, natural light is absent. But gardening experts found an alternative to sunlight - LED grow light.
Why is light important to your plants?
Light is an essential part of plant lives. It is through photosynthesis that plants, like vegetables and herbs, can produce consumable food.
Plants use sunlight and convert it into energy. Plants use at least 70% of sunlight throughout the photosynthetic process. Without sunlight, plants, such as vegetables and herbs, would not get adequate nutrition to compromise survival and growth. However, too much of it can potentially lead plants to death.
Home indoor farming became a life-changing instrument of survival. With ultraviolet light or LED grow lights, most plants, like herbs, can thrive without the fear of receiving too much sunlight and experience its adverse effects.
Grow lights are necessary components in growing plants indoors. Everything is capable of producing light without harming the plants excessively.
What to look for in a grow light?
The next thing to worry about is what to look for in a grow light. Knowing what to expect can help not only the plants but also indoor farmers.
If we opt to go for herbs, there are grow lights that are suitable for herbs. There are also lights perfect for vegetables. These are some of the criteria that indoor farmers and starters should consider:
Distance between grow lights and plants
We do not want our growing herbs or vegetables to die from burning and over-exposure. Distance between grow lights and plants is a significant factor. The distance between the lights and plants depends on the wattage of the lights.
Heat and grow lights
Grow lights emit heat, which also responsible for the survival of a growing herb or vegetable. Since grow lights are artificial, they tend to be a little harmful than sunlight.
It emits a certain amount of heat that can affect growth. Thus, the need for vertical clearance between the plants and the grow light is necessary.
Color, Lumens, Lux, PAR, and Wattage
These are the technical aspects of grow lights. The color spectrum is a manipulating variable responsible for plant growth.
Lumens are a unit responsible for the light that a growing plant is capable of absorbing.
PAR or Photosynthetically Active Radiation is a spectrum where indoor farmers can identify which light a plant responds best through photosynthesis.
Wattage affects the efficiency of a grow light.
Everything helps indoor farmers decide which grow light is adequate at a particular stage of growth. They cannot blindly pick a light because most plants can be photo-sensitive.
It pertains to the generating cost of the grow lights concerning the growing space. Since they use electricity, generating cost is an expected outcome.
Unit economics entails electric bill consumption amounts and wattage of the bulbs. We do not want to go overboard with spending too much without a guaranteed ROI (return of investment).
Different types of indoor light
Can you grow herbs in low light intensity?
Choosing a grow light for indoor herbs and vegetables is vital. Beginner indoor gardeners must not mistakenly choose a particular grow light at the earliest stage of growth just because it looks fancy.
Here are indoor light types and how gardeners should use them in indoor farming - fluorescent lights, high-intensity lights, and LED lights.
Fluorescent grow lights
The fluorescent grow lights are suitable artificial lights for indoor herbs and other plants. Fluorescent bulbs are long-lived and are energy efficient. Fluorescent grow lights work great with seeds, cuttings, and plants like lettuce.
HID lights or High-intensity discharge lights
High light intensity is commonly utilized in most greenhouses. These high-light intensity lights are used as supplementary light.
High light intensity discharges a lot of heat, so vertical clearance between plants and these lights is essential. However, the high light intensity has surprisingly long-lived bulbs.
High-intensity lights work best with flowering and fruiting plant growth stages.
LED lights or Light-emitting diode lights
LED is the latest supplementary light for indoor vegetation. It is known to be energy-efficient and relatively long-lived.
LED bulbs can be customized, either emitting red or blue light spectrum alone. However, the LED light produces little heat. It works best for all plant growth stages because of its variety in wattages.
Placing grow lights appropriately
Installing the bulbs of the chosen lights can be quite a task, especially for a newbie. Here are some considerations in placing lights appropriately.
The number of bulbs needed
Placing all 100 bulbs in a tiny space can be a tad excessive and potentially kill your indoor herb. Always consider the wattage of the bulbs.
Create a light rack
A light rack does not only support the light bulbs in place. They also support the indoor plant by creating a distance between them and the bulbs. The rack both works for indoor plants that retain their growth and those that grow at certain lengths.
Add important accessories
Accessories do not only beautify growing an indoor herb garden or any indoor plant. They also play a vital role in growth.
Accessories like ventilation can help in regulating the heat emitted by the light source. A timer can be used as an accessory to ensure that indoor herbs and plants get an adequate amount of light from the source.
Symptoms of under and overexposure
While the absence of natural light does not guarantee success in growing indoor herbs, these plants can still be at risk of under and overexposure.
A grow light for herbs, and other plants and vegetables can contribute to particular symptoms to under and overexposure of plants.
Scientifically, leaves are where the food-making happens. Without a sufficient amount of light from the source, leaves would not be successful in creating food, leading to its eventual death.

It is not a matter of whether a person has a green thumb or not. It is a matter of how a person takes care of indoor herbs.
Herb gardening is now a trend and are tips for growing indoor herbs successfully. Because most likely, it is all in the lighting.
