Red light. Green Light.

Recently, someone asked us “What is the best way to light marijuana?” We thought of 3 ways you could do this. There is the most common way which is to use a lighter, the more traditional route with matches, and the ultimate earth friendly option of using a magnifying glass. Okay, so starting the post like this seemed much funnier before we actually wrote it.

In all honesty, we were asked if marijuana does exceptionally well under certain colors of light. We were able to rule out the color green pretty easily, because plants our green. Everything we see appears to have color because that is the light which is reflected by the object. Plants, in particular marijuana plants, are green because the reflect, and therefore do not absorb green light.

All the colors of visible light have a wavelength that fall within the range of 400 and 700 nanometers (nm). Green light has an approximate wavelength of 510 nm. Very similar in wavelength to green light, is yellow light with a wavelength of 570 nm. Red light has a lower wavelength and blue light, higher.

The red a blue wavelengths are needed by plants in order to produce chlorophyll A and chlorophyll B. This is why the LED grow light set ups have red and blue LED’s. Unfortunately, these lights are not very powerful.

We recommend using an Eye Hortilux bulb in your set up. Metal halide bulbs have more blue spectrum light and are better for vegetative growth, while high pressure sodium lights produce more red spectrum light and are better for the flowering stage. Hortilux produces both, and we recommend them on the basis of their customer service, warranties on their products, and because they are proudly made in America.

If you have any further questions, or need clarification on anything we have said, please feel free to cnatact us by posting a comment to this post or emailing us at mjmbmail@gmail.com.
