While the wattage of the light produced by the CFL bulbs is more important than the spectrum of light, optimizing the spectrum is a good idea.
They come in a variety of different bases, so flexibility when designing a grow operation won’t be a problem. CFL lights don’t use excessive energy and don’t heat up as high as some other specialized grow lights for marijuana.
How To Grow With CFL
Let’s take a look at CFL lights for growing weed. There are quite a few options for lighting when looking to grow cannabis indoors. CFL lightbulbs are becoming more popular because they are beginner-friendly and easy to use. The best CFL lights for growing weed will help you produce more marijuana in small spaces than you thought was possible. If you have a small space that you want to utilize for growing ganja, CFL lights may be the best option!
What Are CFL Lights?
As mentioned, the coverage of one CFL bulb will only produce enough light exposure to about 12 inches away from the bulb itself. This means that you’ll probably need multiple lights per plant to account for lateral growth.
Aside from the finer points of nailing down your supplemental lighting game — distance from the plants, the quality and spectrum of the light, lighting schedules and timers — perhaps the best place to start your journey is with the bulbs themselves. While you can park a plant in a window and let it do its thing, if you want to coax your indoor plants into optimal productivity and yields, supplemental lights are the way to go.
To summarize the pros of CFL bulbs, they are:
The cons of CFL bulbs
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.
These will never match the light-giving powerhouses that are LEDs and HPS systems, but a well-cared for plant underneath a good CFL system will indeed bear fruit.
CFL bulbs are a great introduction to the indoor cannabis growing arts and should be seen as a perfectly respectful way of going about things.
The amount of wattage these bulbs use is almost negligible for most grower’s power bills. Compared to other ways to grow indoors, the amount of energy saved is worth noticing.
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.
They’re also a good choice as a supplementary light that can be aimed easily due to them fitting into easily moved light sockets. Aim some of these to the side or underneath a plant that is already doing well via a different type of light and it will add a lot to the growth below the light-blocking canopy on top.
On the bright side, pun-intended, these are bright lights, which come in a 4-pack, and will provide plants with enough light to survive and grow, but at a slow rate.
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.
Small & Low-budget Grows
The spectrum of light that a CFL gives off is measured with kelvin, or “K”. The day-light spectrum, which is best for everything but flowering, is between 5500K and 6500K, with 6500K being the bluest and best for vegetative and seedling growth stages.
This is a four-pack of day-light spectrum CFL bulbs for an absurdly good price that, combined, will be plenty to grow cannabis into maturity. The Philips T2 Spirals will not last as long as the aforementioned Emart brand product; however, if a single grow is all you’re after, look no further.
