That means you will choose either…

Recommended For: People who want a super-cheap, super-easy grow style.

CFLs lose a lot of light the further away they are and their light is almost useless once the plant is 6-8 inches away.

Have lots of space; if you have at least 5 feet of height in your grow space, I recommend upgrading to a more efficient grow light.

When it comes to CFLs and cannabis you basically can’t give your plant too much light. With more powerful types of grow lights (like HPS or LEDs) you can light-burn your plants even in cool temperatures, like a sunburn. But with CFLs it’s almost incredibly difficult to give too much light so your main job is to get as many bulbs as you can as close to the plants as possible (without burning your plants from heat).

D.) Mix & Match! Just aim for about 150W of CFLs in Total Per Plant to Start, and stick to relatively smaller size bulbs if you can! If you want them to screw into regular light bulb sockets, use ones with a “medium base”.

Unlike high-intensity discharge (HID) lights that are often used to grow cannabis, CFL bulbs don’t need special fixtures or setups — they will screw into any lamp you already have for incandescent bulbs. This — combined with the fact that they don’t generate a ton of heat — makes CFL bulbs good for small grow spaces. CFLs also come in a variety of temperatures, meaning you can adjust to the plant’s need in the vegetative and flowering stages of growth.

CFLs were originally developed to replace incandescent bulbs, which are not all that energy efficient. Compared to incandescent bulbs, CFLs last 10 times longer and generate much less heat (which is actually a good thing for indoor cannabis grows). Thanks to LED lights, they’re no longer the most energy-efficient option, but they do require less wattage to deliver the same amount of lumen output as incandescent bulbs.

The pros of CFL bulbs

Compact fluorescent light bulbs do contain a small amount of mercury, and mercury can be dangerous. On the plus side, manufacturers have drastically decreased the amount of mercury they use in CFLs and are trying to reduce that amount even further.

While cheaper for initial setup, CFL bulbs have a shorter lifespan and are less efficient than LEDs, meaning they will cost more in the long-term. As mentioned, CFLs also contain a small amount of mercury, which can pose some risk to you and other living creatures in the vicinity should you break one. (Read on to learn more about that.) Because of this, they also require special disposal to avoid sending mercury into landfills.

What is better, LED or CFL bulbs?

The answer depends on where you live. As of this writing, the fate of CFLs is unclear due to some backtracking by the Department of Energy around efficiency requirements for light bulbs that were supposed to come into effect back in 2019. The matter is currently being litigated and, much like cannabis laws, there is a patchwork of regulation that varies by state.
