Young and mature plants, or vegetative and flowering plants, respectively, like different types of light, and you can buy grow lights that target each spectrum. Commonly, growers using HIDs will use MH bulbs for vegetative plants and HPS bulbs for flowering. Some LEDs are also designed to target different light spectra.
Factors to consider before buying a grow light
CFLs (compact fluorescent lamps) are fluorescent lights similar to what you’d find in a school or office building, but smaller. For growing weed, they are usually called “T5s”—the “T” stands for “tubular” and the “5” refers to its diameter, “⅝”.
How much does a grow light cost?
Here are a few different HID grow lights at different price points.
Metal Halide (MH) Grow Lights
3.) LED Grow Lights
Pros of Fluorescents
“LEC” and “CMH” both refer to Ceramic Metal Halide grow lights, which is a type of HID light that is a bit more efficient than a regular Metal Halide light
T5 grow lights are one of the most easily available types of grow lights and are used to grow many different types of plants. As a result, they’re available in many garden and home improvement stores.
Pros and Cons of HID Grow Lights
Fluorescents are a great choice for clones, young plants, supplemental lighting and can save you money on electricity in the vegetative stage compared to using high power lights when plants are too young to use it all anyway. They can also be used to flower plants in spaces that are shorter than what’s possible with other grow lights (aka ‘stealth growing’).
You can hang the lights overhead, vertically, or horizontally closer to the plants according to your preference. There is a 10ft grounded power cord to help you reach, and the powder-coated steel housing protects the T5 tubes.
Please note that this bulb is not the best on the market. However, it is cheap and will do the job in the smallest grow tents.
There is much debate about what lighting type is the best for marijuana. Fluorescent lighting is a commonly used form of lighting, but you still need to learn which bulbs work best. In this guide, we cover the pros and cons of fluorescent lamps and explain where you can pick up the best fluorescent light for your grow space.
HIDs (high-intensity discharge) are even more powerful, but they aren’t as energy-efficient and they use a lot of power. As such, they can give off quite a bit of heat. You may need to invest in a ventilation system to counteract this, leading to a higher cost.
3. EnviroGro FLT24 2-ft T5 Bulbs
LEDs (light-emitting diodes) are a favorite with growers because they last long, are super energy efficient, and emit very little heat. Still, they are powerful enough to produce high yields at the end.
Although this model doesn’t offer vertical positioning like the EnviroGro FLT24, it does offer two modes of light. Switching off some of the tubes allows for dimmer light that works better for times when you need it a little darker.
As you can see, choosing the best fluorescent light is a bit of a trade-off. That’s why professional growers will change between different types of lights during different stages of growth. If you’re not that serious, though, and are just planning on growing one or two plants, then fluorescent bulbs will work just fine.
5. Hydrofarm FLCDG125D Fluorowing Compact Fluorescent System
There’s a lot to learn when you enter the world of marijuana growing. Newbies are confronted with a vast wealth of information and a steep learning curve. You need to learn about watering, feeding, pruning, and more. But before you even begin to grow your cannabis plants, you need a set-up.
While fluorescent lighting may work for small-time growers with a handful of plants, you will need to invest in an upgrade if you’re wanting to produce more marijuana. LEDs and HIDs are much better for getting a higher yield.
