Can you grow weed with cfl lights

In an ideal setup, you should be using both types of bulbs to meet the needs of your plants at different stages of their life cycle: daylight for the vegetative stage and warm white for the flowering stage.

To summarize the pros of CFL bulbs, they are:

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.

We’ll get into the shifting legal landscape of CFL bulbs in a minute, but generally speaking, CFL bulbs are still pretty easy to find at local hardware stores and even grocery stores in most states.

Can you still buy CFL bulbs?

Compact fluorescent light bulbs use a combination of argon gas and mercury vapor to produce light. When exposed to an electric current, the argon and mercury combination generates an invisible ultraviolet light. This light hits a fluorescent coating on the inside of the tube, and voila, visible light.

There are lots of lighting options available to the home grower, but for now, let’s dig into one specifically: compact fluorescent light (CFL) bulbs. Widely available and simple to use, CFL bulbs are often employed by home growers of all skill and interest levels. So let’s unpack them for you.

The only real risk CFL bulbs pose is if you smash them. When that happens, the mercury vapor escapes and it could pose a risk to you, other humans, and pets. If you break a CFL bulb, be sure to keep kids and pets away, open the windows, and don’t vacuum. The Environmental Protection Agency provides a very helpful guide to cleaning up broken fluorescent bulbs.

The cons of 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.

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.

Using CFL bulbs for plants and producing marijuana on your own doesn’t have to be complicated. CFL lights are the most beginner-friendly setup. They are also the best choice for small spaces. Beginners shouldn’t grow too much for their first experience, meaning CFL lighting is a win-win for cannabis growing for beginners.

CFL Light Bulbs For Growing Weed

You can grow marijuana with CFL grow light bulbs in soil or hydroponically. Regardless of the growing medium, light needs remain the same.

How To Grow With CFL

CFL is an acronym for compact fluorescent lighting. Compact fluorescent grow light setups are easy to build out because you can buy CFL grow bulbs at almost any store that sells light bulbs! They are just like fluorescent light bars seen in stores and offices but packed into a small lightbulb, allowing the user to reap the benefits of fluorescent light without a large lamp setup.
