Why Choose Full-spectrum LED Grow Lights?

Full-spectrum LED lights emit wavelengths of light between 440 nanometers and 700 nanometers. This band of light included infrared light and ultraviolet light.

Since your cannabis plants can make use of this full spectrum, it pays to look out for lights packing the full spectrum. Look closely at the brand you have in mind – more on those right below – since many will claim to be full spectrum without including IR or UV chips.

It’s perfectly possible to grow without infrared or ultraviolet light but you tend to see your plants suffer from more mildew and mold in the absence of these lights.

With full spectrum lights, you’ll usually get 2 modes:

• Vegetation Mode: Your light uses half the energy and less red light
• Flowering Mode: When your plants start flowering, they’ll need full power and more red light

How to Avoid 5 Common Problems with LEDs

Here are some common issues with LED lights and how to prevent them from ruining your grow…

1.Insufficient Light: Think carefully about how many plants you’ll be growing and don’t sell yourself short with inadequate lighting. Take the time to think about the number of lights and their luminosity before purchasing your LEDs.

2.Overheating Your Crop: If you spot the leaves closest to the lights turning brown, you know you’re overdoing it with the LEDs. Take action promptly if you see any thin outlines forming on the leaves.

3.Incorrect Placement: If you put your LEDs too close or too far away from your plants, you’re inviting disaster. As a general rule of thumb, set them up at a distance of between 12 and 18 inches from your crop for best results.

4.Faulty Spectrum Selection: Your plants need different light for different stages of growth. Blue light is better for the vegetative stage so if you fire in too much red light at this point, you’ll stunt the growth of your plants.

5.Failure to Adjust Your Lights: If you don’t fine-tune the height of your lighting as the plants grow, you are highly likely to end up burning the leaves of your precious marijuana plants.
