There are a variety of grow lights for growing plants on the market, each with its own unique advantages and disadvantages. In general, however, grow lights can be roughly divided into two main types: HID (High Intensity Discharge) and LED (Light Emitting Diode).
HID grow lights are generally more powerful and emit more heat than LED lights, making them ideal for larger grow jobs. However, they also require more energy to run and generate more heat, which can be a problem in smaller grow spaces.
LED grow lights are becoming more and more popular due to their energy efficiency and low heat output. While they may not be as powerful as HID lights, they can still produce great results and are a great choice for smaller grow spaces.
Some LED lights are full-spectrum, which means they mimic the sun in the light they produce. There are also options that produce higher UV/IR ratios, which tend to speed up the growth process and increase yields.
No matter which grow light you choose, it’s important to make sure it’s installed and positioned correctly for best results. If you’re growing plants indoors, you’ll also want to invest in a good ventilation system to help remove excess heat and humidity.
It is impossible to grow plants indoors without lights. If you plan to grow in a controlled environment, the simple answer is yes — you need grow lights. All plants require energy in the form of photons for photosynthesis. Your plants can survive indoors using ambient light from household light sources and windows, but it will have zero productivity.
While it is technically possible to grow plants using standard bulbs, it is not recommended. The light they produce is limited in range, spectrum and intensity. They also generate a lot of heat, consume more electricity, and have a shorter lifespan than grow lights.
Household bulbs are not designed for plants. Adequate lighting solutions for your crops are essential if you want to achieve high yields.
Spider Farmer G5000 480W Full Spectrum LED Grow Light
Features:
Spider Farmer G5000 led grow light has a unique elongated light bar design, which provides more even and comprehensive canopy coverage. Equipped with 1680 high-efficiency diodes, the G5000 LED grow light delivers 480 watts, achieving an impressive 2.8 umol/J PPE, covering a highly productive full-cycle grow of 4x4 feet. The G5000 Grow Light is a full-spectrum LED grow light (660–665nm, 3200–4200K, 4800–5000K) with different wavelengths of light, perfect for every stage of plant growth. The dimming button can adjust the brightness of the light, 10–100% dimming to meet the needs of plant growth.
BESTVA BAT W400 Dimmable LED Grow Light
Features:
The BESTVA LED grow light is the solution for indoor growing environments where ceiling height and distance from the tree canopy are critical. The BAT W400 is ideal for use in vertical racks, low rooms, benches and even tents. The grow light provides an efficient full spectrum and a healthy red-blue ratio to drive photo composition. Light energy between 500–599nm, previously thought to be wasted, penetrates deep into the plant canopy and promotes photomorphogenic responses. High colour rendering “white” light helps quickly identify potential threats to crops and provides superior working conditions and safety for workers. It is great for flowering and plant production.
When it comes to grow lights, there are three main factors to consider: the color of the light, the energy cost of the fixture, and the intensity of the light. Before we compare LED lights vs. fluorescent lights, let’s understand the needs of plants.
Light Color
We all know that plants need light to thrive, but have you ever wondered how the shade of light affects plant growth?
The sun produces the full visible spectrum, including red, orange, yellow, green, blue, indigo, and violet. This is known as full spectrum or white light.
Most houseplants thrive in full-spectrum bulbs, which produce a balance of warm and cool light that mimics (or at least tries to mirror) the sun. Seedlings, houseplants, culinary herbs, and a variety of other plants thrive in this full-spectrum light.
In general, blue light promotes leaf and stem development. Red light promotes flower development, making it essential for fruiting plants. However, there is a wealth of information available regarding the unique advantages of red and blue light. Some of them are also deceptive.
Par and Lumens
It’s easy to overlook the fact that plants and humans receive light in completely different ways. Humans use photopic vision to perceive color. Photosynthetically Active Radiation (PAR) is the wavelength of light that drives photosynthesis in plants. An excellent article on the difference between PAR and lumens can be found here.
PPF (Photosynthetic Photon Flux) refers to the total amount of light produced per second by an LED, fluorescent lamp or other light source. This is what we call the intensity of the grow light. The unit of measurement is micromoles per second (umol/s).
What is the PAR value of the lamp?
The wavelength of light that stimulates photosynthesis in plants is PAR (Photosynthetically Active Radiation). We use the photosynthetic photon flux to calculate the amount of PAR produced by the system per second (PPF). PPF doesn’t indicate how much measured light reaches the plants, but it’s a must-know if you want to determine how efficiently your lighting system is producing PAR.
Now that the topic of the best lights for indoor growing has been shed light, get out there and start your adventure.
If you have an indoor growing facility, you need lights. Whether you choose CFL, HID or LED depends entirely on your space, pressure and of course your budget.
