If you are searching for the right grow lights for your autoflowering cannabis plants then you might consider autoflower CFL grow lights. There are only three popular types of grow lights for marijuana: CFL, LED and HPS. Of all the three, CFL is still the most widely used, find out why this is so and why many think CFL has a better advantage than other types of lighting by reading this short guide.
Why use CFL lights on Autoflowering Cannabis
More and more cannabis growers convert from their old lamps to a bright CFL lamp. However, some remain unconvinced. They assume that CFLs are inefficient because of their light output per watt. Some experience cultivators think that this quality of light will only grow very small plants and hence will reduce their yields.
Fluorescent lights have a higher photoactive radiation index compared to HID lights, therefore, no matter how bright and how hot HID lights, these are still inefficient.
Meanwhile, there are several areas along the spectral scale that cannabis uses light. Take green light and yellow light, these are rarely used. Compared to HPS lights that give off yellow light, CFL emits red or blue depending on the type of bulb that you are using. These colors will be able to create the same yields or maybe improved yields.
Different CFL Lights and Efficiency
You can find CFL lamps in various shapes, wattages and lumen outputs. But not all of these have similar efficiency ratings. Shapes of the bulbs are either spiral or tubed bulbs.
CFL bulbs nowadays have a longer and thinner shape while spiral bulbs are shorter although wider. With a lot of options for you, you need to select the bulb that’s perfect for your needs.
About efficiency ratings, a bulb with a tube or spiral shape is not an issue because the wattage is a more important component and usually the most calculated of all the values is the lumen per watt ratio of the bulb.
For instance, a 42 W CFL bulb provides 2700 lumens. You need at least two of these to improve light plus to get the best yield per bud. Meanwhile, cannabis plants require anywhere from 5000 to 10000 lumens per square feet of growth. It’s a must to measure your growing area to find out how much light you need for your plants. If your growing area is 10 square feet, therefore, you need 20 CFL bulbs for the best lighting solution for your plants.
Where to Place your CFL Lamps?
Usually, growers just place these around the growing area to get the best results.
About CFL Colors
Do you know that cannabis plants will grow better if you take advantage of the different CFL colors? These plants actually require different types of light during their different phases of growth. During the seedling to the growing stage, plants will grow better when exposed to more blue light. But during the flowering stage, plants will grow better and develop better buds when exposed to more red lights. Cannabis plants may use all the colors in the light spectrum except green.
Color and Temperature
What about CFL colors and temperatures? Is there a right color temperature for cannabis plants?
There are two color and temperature categories measured in degrees Kelvin or K. One is the 6500 K for plants that are still in their seedling and growing phase. For the flowering stage, 3000 K to 4000 K bulbs will suffice. Take note that these bulbs will have different colors, therefore, these will give plants more diverse light.
