For the money, we think this is the best CFL light for growing cannabis.

CFL’s are the popular entry-point into indoor growing, both with cannabis and other plants as well. However, finding the right CFL for growing cannabis can be a bit trying. There is a massive market and a plethora of reviews to go over, and it’s hard to tell what is best to use for any given situation without first-hand experience.

A Quick Comparison of Our Favorites (2022)

We look for CFLs in this range due to their ability to grow cannabis successfully, and we leave the flowering stages to the more powerful lights that can dive deeper into the lower, red spectrums. There are 2700K CFLs available, but they don’t do a much better job than the daylight spectrum does at the end of the process.

There are bulbs with different CFL color spectrums and it’s generally recommended to get “daylight” (6500k) CFLs for the cannabis vegetative and “soft white” (2700k) CFLs for the flowering stage. Each color spectrum has a small impact on how the plant grows (ex: 6500k encourages slightly more squat growth).

Soon after I started growing, I upgraded my growing environment by getting a grow tent. If you want to start out with a turn-key grow space without any work setting up, you might want a grow tent. You can buy a small grow tent that’s perfect for growing cannabis with CFLs! A 2’x2’x4′ grow tent is great for CFLs and will easily fit in the back of your closet. A bigger 2’x4’x5′ grow tent is also be a good starting tent size that can be upgraded with bigger grow lights later.

For example, 4 x 40W CFLs (at 160 watts total) will usually get bigger yields than a cannabis plant grown under 1 x 200W CFL, even though the smaller bulbs use less electricity in total.

Examples of Great Spots to Use CFLs

Adjust CFLs Regularly – You want to adjust your CFLs around your plants as they grow, so make it easier on yourself by setting up your CFLs so they can easily be adjusted in your grow space. Keep in mind that CFL adjustment can be a daily task!
