Planning to grow herbs indoors? Growing sustained, harvestable amounts of herbs indoors require long periods of intense light (6–8 hours of direct light for most varieties).
Why? Abundant light is essential for helping herbs produce the oils that give them their distinctive flavors.
Without the right amount of light, your herbs won’t taste much like … well … herbs.
Sunlight is ideal for herbal plant growth, but when growing indoors it’s not always possible to get enough, especially during the winter months.
The answer is that plants require a much higher light intensity to grow plants effectively than humans need for vison. The minimum light intensity required to grow plants is at least 30 times greater than required for human lighting in an office environment for example.
High light intensity is required to drive photosynthesis which generates plant growth. Photosynthesis occurs when photons of light reach the plant leaves and causes a reaction which generates plant growth. The measure of light intensity for plant growth is called Photosynthetically Active Radiation or PAR and includes photons of wavelengths from 400nm to 700nm or from deep blue to deep red. It is about the same range of wavelengths as the visual range for humans.
LED grow lights are designed to withstand the high humidity in a grow room and will be able to withstand condensed water dripping on the grow light. The LEDs are often protected with a silicone or acrylic coating and the connectors and cables are Ingress Protection (IP) rated so that they can operate in damp conditions.
Viparspectra KS2500 250W LED Grow Light
Features:
The VIPARSPECTRA LED Grow Light uses the market leading Samsung LM301H diode (3.10 μmol/J), a more energy efficient LED that increases crop yield and saves operating costs. The KS series is designed for individual or commercial growers who want to optimize their growing space for maximum crop yield while producing the highest quality crops. Composed of 3000K warm white, 5000K white, 660nm deep red and IR730nm, it provides your plants with an excellent spectrum, tailored for germination, vegetative and flowering applications in indoor environments. The KS2500 delivers high light output and consistent uniformity with market-leading efficacy, consuming only 250 watts of perfect light for 3'x3' coverage.
FloraGear FLORA X4s 240w Full-Spectrum LED Grow Light
Features:
This FloraGear LED grow light is ideal as a stand-alone light for small tents, or as a “travel” light in larger HPS or CMH grows. Designed for serious growers, the FLORA X4s are equipped with OSRAM LEDS and are the ideal system for vegetables and bloom/bloom spaces up to 3'x3'. Designed and built for rugged reliability, the grow light’s 240-watt full-spectrum LED light provides the steady input plants need to reach their full genetic potential during the vegetative and flowering stages. Can be part of a system of up to 100 lamps using an RJ14 hardwired network. It is designed to operate in wet spaces: the transparent lens hood protects against moisture.
There are a couple of factors you need to put into consideration before choosing a LED to grow light. There are lots of advantages to getting LED to grow light and compared to incandescent lamps, they are energy efficient and emit less heat too. LED grow lights are available in different sizes, intensities, colors to suit your plants.
So to make sure you are choosing the right one for your indoor plants, here are factors to consider.
1. Power Consumption
Since LED lights are designed to emit less heat then you need to make sure they are energy efficient. Although they are made to consume less energy but high-power LED lights should be chosen carefully. But typically you should expect energy savings to the tune of 25% to 30 %.
2. Light Spectrum
The colors produced by the LED grow light plays an important role in the growth of your indoor plants. LED grow light needs to be user-friendly and not so bright that it hurts your eye. Ensure you are choosing one with quality light and easy-to-operate features.
3. Duration
How long the light is going to last is also another very important factor. It is important to go for one that can provide your plants with light for a period of 24 hours and also ensure it can be controlled. A programmable timer should come with it so you can easily turn the lights on and off.
As you can see, there’s plenty to consider when shopping for a new LED grow light. But the most important aspects to keep in mind when shopping are the PAR your plants need, the wavelengths they need to thrive, and the footprint of the lights you’re looking at.
When you know the light intensity your plants need, what wavelengths they thrive on, and how much area you have to cover, you can pin-point the exact grow light you need. From the size to the type, the more you know about your plants, the easier you’ll find the right light. So when you have the right light growing your plants, you’ll get the yields you’ve been working toward.
And you’ll do it using less energy while getting more intensity over HID’s.
