    Our most frequently asked questions on CFL grow light.

    What is CFL grow light?

    When Thomas Edison devised the classic incandescent lamp, it was one of the greatest inventions at that time. But today, these bulbs are no longer efficient ad that’s why CFLs were created to replace them.

    In full, CFL refers to compact fluorescent lights. These lamps are easily distinguished by their spiral, curly design. As a result, these lights are more compact than fluorescent bulbs.

    What to consider when selecting a CFL grow light?

    Since there are several CFL grow lamps to pick from, it is vital to know what type of grow light will be ideal for your grow tent or grow room.

    And if you want to select the best light, then you should consider the following factors: wattage, lumens, and kelvins. These factors will help you land a lamp that suits your plants and grow space.

    How far should I put the CFL light from my grow plants?

    Unlike other bulbs, the CFL lights don’t put off a lot of heat; thus, you can install them close to your plants. You can install them somewhere between 2-inches and 4-inches.

    Putting other types of bulbs like LEDs and HPS close to your plants may burn them. But this is not the case with CFL lights. However, you should adjust them accordingly as they can also burn your plants if they are extremely close.

    Why should I use CFL grow lights instead of other types?

    Instead of using lights such as HPS, LEDs, or metal halides, you can CFL grow lights in your grow room because of these reasons.

    First of all, CFL grow lights are cheap when compared to the ones that we’ve mentioned. Secondly, these lamps are easily available.

    Also, they consume little electricity and don’t produce a lot of heat. Besides, you don’t need special fixtures to install these grow lamps.

    How much wattage do I need per square foot?

    The wattage of a CFL grow light is crucial because it shows its performance. Also, you should calculate wattage per square foot so that your plants don’t get less or more.

    It is recommended that you provide between 80 and 100 wattages per square foot. Most plants need 40 to 70 watts. So, if you have three plants in your grow area, then you may require a total of 150 wattages.

    Bottom line

    CFL grow lamps are the perfect lights for new growers with small grow rooms. The lights are cost-effective, easy to install, compact, versatile, and produce less heat.

    What’s more, you won’t have to change them during different stages of plant growth. Also, most of the CFLs run cool, so you won’t need fans to keep them cool.

    However, compact fluorescent lights are not very efficient and have a shorter lifespan. Overall, these are quality grow lamps that will help you growing plants indoors healthily and get higher yields. Take your time and pick the best CFL lamps from our list above.
