can you grow cannabis with white led lights

Grow lights are a great tool for making the growing process more efficient, but they can also be harmful to the plant if not used correctly. Here are 10 things you should avoid doing when using LED and other types of grow lights.

Providing Insufficient Lighting
It is important to consider the scale of your operations. Think about how many plants you’re growing and how many LED lights you’ll need in order to illuminate them properly. You should also be aware of the luminosity of the lights you’re using. For example, a 200W LED light is said to be sufficient for a yield of about 100 grams. Make sure that you have enough lamps but still look for a good balance between providing sufficient lighting and not overdoing it.

Overheating the Plants
You will know the plant is taking too much heat if the leaves that are closest to the light start turning brownish. The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.

5000K light contains more red than a 6500K light. Red light actually helps a lot during vegging too, but since the cooler light also still contains quite a bit of red, it is better if only vegging.

6500K LED light is definitely a vegging specialist. If you plan on doing nothing but vegging or cloning, then a cool light like this is ideal.

As a result, I would only recommend cool LEDs like these if you are vegging and nothing else. If you will also be using the light to flower, you want a color temperature of 4000K or lower. If you are vegging only, then 6500K light is better than 5000K, though both would work great.

Doesn’t that mean that white light is less efficient than a “blurple” LED?

When these phosphor-coated diodes were first introduced, the spectrum was fairly narrow. But the use of difference phosphors and different blue wavelengths led to ever-broader spectra.

So what’s the truth? Is white light any good for growing plants?

As you can see from the spectral chart above, today’s white LEDs emit light in every visible wavelength. How much of each wavelength they give you depends on the color temperature of the light.

When it comes to LEDs, you generally find either 3000K or 3500K. 2700K is not common in LEDs, but is the color temperature of many HPS or CMH bulbs.

But now we are being told the opposite. That full-spectrum white light is, in fact, better.
