Top 10 Tips on Using Indoor LED Grow Lights
With advanced indoor LED lighting systems, growers are able to cultivate different plants with a lot of ease. These LEDs produce light at controllable ranges, allowing your plants to grow under full spectrum of light. Indoor LED grow lights are designed to emit light in all the three spectrum in the best PAR range. LEDs are effective, especially during vegetative stage.
Today, LED grow lights are becoming increasing popular for growing numerous plants, including cannabis.
But not all growers that use LEDs end up with better crop yields. This is happening maybe because of poor installation, poor manipulation of light and dark cycles, and poor distance between the LEDs and the plants among other factors. Now that you have decided to plunge inside the world of indoor planting with LEDs, don’t let this happen to you.
So, here are the best tips on how to use indoor grow LED lights to achieve growth and yield you want.
Tip #1: Keep Watch on Your Light
You need to provide your plants with sufficient light coverage to realize robust growth. Incorrect mounting of the lights will cause lower yields. Mounting the LED lamps too close to the plants will cause stunted growth while mounting the LEDs far away causes stretching.
KIND has experience designing indoor LED grow lights and providing expert advice on coverage for optimal light penetration. Different variables influence indoor growing, so you need to adjust light for robust photosynthesis. Indoor LED grow lights emit wavelengths of light necessary for seedling, vegetative and flowering.
Tip #2: Define Your Power Need
KIND LED grow lights are designed to provide the most effective photosynthetic activation radiation (PAR) that is needed for plant growth. Plants grow by reaching out for light concentration so you need to provide the light that covers all the parts while ensuring that it penetrates the canopy. This means that hydroponic LED grow lights with different wattage will perform differently at different mounting heights.
For example, a 240-watt LED grow light should be mounted 16-30 inches from the top of the canopy. On the other hand, more powerful lights such as 450-watt lights should be placed 20-30 inches from the top of the canopy. Indoor LED grow lights with a higher light intensity such as the 600-watt lamps should be mounted at 25-26 inches from the top of the canopy.
Tip #3: Manipulate Room Temperature
Since indoor LED Grow Lights do not emit as much heat compared to HPS systems, it is recommended to manipulate the room temperatures and the temperatures under your lights. It is advisable to keep the room temperatures at 82 degrees but this can be adjusted downwards to 60 degrees during the dark stage.
Be certain to minimize the amount of water than you would normally use with traditional lighting since LEDs are not known to generate excess heat like conventional lighting systems. You should monitor your soils to ensure that they are slightly dry before watering again. The amount of nutrients should also be reduced by about 30% as compared to the conventional HPS lights.
Tip #4: Observe the Light Cycles
Do not power on your LEDs when it is supposed to be dark period. The dark period is necessary to allow for the plants to rest and use up the nutrients. It is recommended to use green lights, as they do not interrupt the sleep schedule of the plants during the dark stage.
Tip #5: Know the Height of LEDs from the Plants
It is important to hang or mount your indoor LED grow lights over your plants as it mimics the natural sunlight, exposing all the parts of the plant to the light. If you are using incandescent lights, placing them at 24 inches from the canopy of the plants would go a long way to expedite growth.
Tip #6: Mounting Fluorescents
Fluorescent should be placed 12-6 inches from the canopy because they have a lower heat signature. You should keep manipulating the position of the lights as the day progresses and as the plants grow until maturity.
Tip #7: Add Carbon Dioxide (CO2)
While keeping all the conditions properly dialed ensures your crop growth is consistent, supplemental carbon dioxide can go a long way to ensure a huge difference in your yields. Carbon dioxide is responsible for the weight in your dried harvest, so sufficient CO2 is necessary for better yields. Supplemental CO2 should be added during the lighting cycle and not during the dark stage. Ensure to discontinue it 7-14 days before actual harvest time.
Tip #8: Choose Your Growing Techniques
It is important to manipulate the size of the plants when growing plants in an indoor LED garden.
The screen of green and the sea of green are the two most common planting techniques that you can use to manage the shape and size of your plants while at the same time ensuring uniform coverage and appropriate light intensity.
Tip #9: Be Consistent
Being consistent in your indoor LED garden is important since you can be able to figure out the cause of the problem or identify the cause of the advantage you are enjoying. You should maintain a fixed schedule of changing the intensity of light, temperature, nutrients and light coverage. This will ensure that you adopt a perfect nutrient and light spectrum for better yields.
Tip #10: Ensure No Pathogens
It is essential to keep your garden free of pests and diseases. Pathogens can enter your garden in so many ways but keeping a watch over your garden will help put in place mechanisms to protect your plants. Sterilize your equipment, ensure no unauthorized persons enter your garden, and wash your hands and farm clothes to avid carrying pathogens into your garden.
If you are not sure of the light requirements, consult your particular model or manufacturer for directions. However, it is worth noting that the light requirements depend on what plats you want to grow, so you may want to install different lights at different heights for particular plants.
