How do you use grow lights when growing plants indoors?
Use these steps to use the proper grow lights when growing plants indoors. Determine what type of plant to grow. Purchase the seeds for the variety or flora you wish to grow indoors. Base your decision on the space in your home and the amount of electricity you can use. Vegetable plants require more light than many exotic plants, for instance.
Can you grow plants with regular lamps?
The short answer is no, you can only grow plants with grow lights. Grow lights are lamps that are optimized for plant growth. Unlike regular lamps, they emit the right spectrum and the proper intensity of light that can fuel photosynthesis. The most popular types of grow lights are:
What color grow lights do I need for my grow room?
These lights can come in many different colors. The color depends on the specific needs of your plants and the specific characteristics of your grow room. For example, red, far-red, green, and blue light spectrum have a positive effect on flowering, root formation, and plant growth.
How far should a grow light be from a plant?
Ideally, a grow light or bulb should be placed within a couple of feet of a plant to ensure it receives enough light. It is usually also best to place the light directly above a plant, rather than off to the side as this could cause the plant to grow sideways and “reach” towards the light.

How long should plants sit under a grow light?
To be effective, grow lights really need to be on for at least 8-10 hours a day. This can vary up to 16 hours, depending on the conditions. That's why LED grow lights are so popular – when they have to be left on all day, it's best to use an energy efficient type!
Can you grow plants with just a grow light?
LED Grow Lights are perfect for indoor seed starting, as well growing as light-loving houseplants, such as orchids. With a set of grow lights, you can grow many plants indoors, including houseplants, orchids, and even some fruit and vegetable crops.
Can any plant go under a grow light?
Grow light fixtures are uniquely designed to deliver proper light to all your plants. They won't give off heat and provide a broader spectrum of light than individual bulbs do.
Do plants under grow lights need more water?
Plants grown indoors under lights will dry out quicker than others. Check water daily. Seedlings should be moist, but not soggy. Overwatering is the number one killer of plants.
Can LED grow lights burn plants?
Myth #14: LED Lights Can't Damage Plants The reality is that modern LED grow lights can produce a very high level of light and it can cause photo-bleaching and burn leaves. This depends very much on the plant, but a PPFD of 800 is enough to damage some plants.
Do grow lights have to be above plants?
In general, grow lights should be mounted closer to the plant canopy for vegetative stages of growth and higher up (further away from) the plant canopy during the flowering stages of growth.
What is the difference between a grow light and a LED light?
Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.

What is the difference between a grow light and a LED light?
Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.
What is the difference between a grow light and a regular light?
Regular LED bulbs have a low light output per watt, which means that it takes more energy to produce the same light. Standard fluorescent lights are twice as efficient as normal bulbs, while LED grow lights are about five times more efficient than similar regular bulbs.
What type of light is best for growing plants indoors?
When growing most houseplants, use light bulbs between 4000 and 6000 Kelvin, as the bulb's color temperature will borrow from a full spectrum of colors—cools and warms. With these lights, you can actually mimic the growth you would get in a greenhouse or outdoors.

A tomato seedling may have its light bucket filled for the day in just five hours in full sun, whereas the same plant may need 22 hours of a fluorescent light, just because there are so many more photons coming out of the sun every second than out of the fluorescent light.
How long should I run a grow light for seedlings?
Most seedlings can be grown to transplant stage with high quality T8 four- bulb fluorescent “shop lights,” but the lamps need to be kept close to the tops of the seedlings (less than one foot away) and these lights need to be run for 22 hours to get the DLI ideal for seedling growth of sun-loving plants.
What does a pepper seedling look like?
In seedlings, this looks like stretched, thin plants with lots of space between the leaves.
How many hours of light do I need to grow a seedling?
For example, to reach the DLI requirements for optimal seedling growth, one of the commercially available LED “light bars” I have tested would require eight hours per day if mounted 8” above the crop, but would require 16 hours per day if mounted 20” above the crop.
What is the intensity of light in the wavelengths that plants use?
The Intensity of a light, within the wavelengths that a plant can use, is called “Photosynthetically Active Radiation” (PAR) (also known as “Photosynthetic Photon Flux Density” or PPFD) and it’s what we measure with a horticultural light meter.
How to get the most light out of fluorescent lights?
Keeping the lights close to the plants and raising the lights as the plants grow is a technique to get the most light out of our fixtures. You can purchase adjustable light hangers designed for this purpose. Keep in mind that most fluorescent light fixtures have a “ballast” at some location along their length, and that this ballast often produces much more heat than the rest of the fixture. The plants under the ballast may require water much more frequently or may even burn from the higher temperatures.
What is the term for how long a plant is lit?
How long the plant is being lit between dark periods is called Daylength. Day length is used by the plant to tell what time of year it is, and mostly relates to flowering and fruiting responses. It isn’t terribly important for the production of most seedlings, except for things that need to be kept in a growing phase before they enter a flowering phase (like begonia, poinsettia and cannabis).
