how to grow marijuana with led

It used to be that lighting was one of the most expensive aspects of growing marijuana. A good set of HID or CFS lights could set you back a couple hundred with all the required equipment. Now, thanks to LED lights , cannabis grow lights are much more affordable, making growing cannabis at home much more attainable.

Growing Cannabis Using LED Lights

Those who could not afford a good set of HID lights would resort to CFLs, which, while not as effective during the flowering phase , managed to get the job done most of the time. Often times, these were the only options for growers with smaller operations, or those growing a couple plants for personal use. CFLs have gained some popularity over the years, but they would never be as popular as HID lights, which are trusted by growers all over the world. That is until LED lights entered the picture.

Different Types of Cannabis Grow Lights

Though they work exceptionally well, HID lights are not without issues. For instance, a good setup is very expensive. If your plants don’t produce to your liking, you could find yourself out a few hundred dollars with no way to make your money back.

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.

Not Protecting and Maintaining the LED Lights
LED grow lights are your friend and an important investment, so you need to take proper care of them. They bring numerous benefits to the growing process and a little maintenance and preparation can save you a lot of trouble. It is recommended that you set up a power stabilizer and connect it to the lights in order to equalize the incoming voltage, thus protecting the chip inside the LEDs.

These issues can be related to improper usage of lighting. (The same issues affect other types of plants as well.) 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.

Forgetting to Adjust the Lights
Many people forget to adjust the height of the lights as the plants grow bigger and end up with burnt leaves. Another important thing is to occasionally rotate the pots in order to prevent the plants from leaning towards the light too much.

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.

Quantum-sensor light meters measure photosynthetic photon flux density (PPFD). This allows you to match the light intensity as the plants see it, rather than the visible light seen by humans.

Different varieties of cannabis respond differently to lighting applications. To see the effects of varying spectral ratios on a variety’s growth development, adjust the spectral ratios once plants have successfully transitioned to the vegetative stage and then monitor their growth to identify from these spectral ratios.

STEP 2: Begin to Increase Light Intensity

Average light intensity for cannabis propagation is between 100-200 μmol·m −2 ·s −1 .

See the next article in this series, “How to Transition Cannabis from Veg to Flower”, to prepare for the transition from the vegetative to flowering stages.

STEP 3: Repeat Until Ideal Light Intensity Reached

If your LEDs are integrated with a lighting control software like smartPAR™, you can program your lights to increase intensity incrementally until you reach your maximum vegetative light intensity.
