Frequently Asked Questions (FAQ)

Which color light is best for plant growth?

The most important light for plant growth is blue-colored since the chlorophyll readily absorbs it, and then it transforms through photosynthesis into energy. That being said, blue light alone, without being combined with red, is not nearly as adequate as when it gets mixed with the red one. So, in a nutshell, both blue and red in combination are incredibly crucial for the healthy development of plants in a grow tent or box.

How many plants can I grow with a 300w LED light?

LED lights play a significant role in the growth of plants inside your growing tent or cabinet. More LED lights of higher watts can affect more plants. If the light is insufficient for the plants, their development will not be too active and rapid.
So, if you are using a 300W LED light in your grow tent, it is suggested for you to limited the number of plants till two. Trying to grow more plants with this LED light may not deliver you the results that you require or expect.

Can you leave grow lights on 24 hours a day?

To keep it short, indeed, you can leave the LED lights of your to grow tents on for 24 hours a day, but that is only throughout the growing vegetative phase. Many individuals opt to keep only the lights on for 18 hours a day, even in the increasing vegetative stage of marijuana that is for a good cause.

Since dark reactions do not need a deficiency of light, plants should stay safe 24 hours a day when exposed to the light. Nevertheless, there are some plants that could strive without darkness but not flourish.

Which color causes the most plant growth?

Differently colored lights are helping plants achieve different targets. For instance, blue light tends to promote the growth of vegetative plants. Red light aids the plants to bloom when paired with blue.

In conclusion, for the growth of plants, blue light is the most important one. Blue light is responsible for controlling the opening of stomata, the tiny openings on leaves that monitor both water depletion and carbon dioxide absorption. In general, for full functional photosynthesis, only a low intensity of blue is needed in a light spectrum.

Is white light good for plants?

Cool fluorescent LED light is perfect for indoor growth of plants. White light given by fluorescent tubes is a wide spectrum light that combines various colors which are beneficial for plants. For this cause, a conventional fluorescent light is one of the most excellent sources for light to use in grow tents. White LEDs, by comparison, do not offer a wide spectrum.

Can plants survive with LED light?
