Grow Lights for Weed
Today we’re going to talk about the different grow lights for weed that allow you to grow cannabis indoors. Thanks to technological advances made over the last few years, there are an incredible amount of choices when it comes to growing cannabis indoors, which is great but can also be a bit daunting when it comes to choosing the right lamp for you.
In order to make this a bit easier for you, we’re going to have a look at the different types of lamps and bulbs that we work with here at Growbarato.net, all of which you can purchase in our retail stores or on our online store.
Grow Lights for Weed | Gas-discharge lamps
Discharge lamps are lamps that contain certain types of gases which, when given an electrical current, produce a certain type of light. The spectrum differs in regards to the type of gas in the bulb.
The most common discharge lamps on the market are HPS (High Pressure Sodium), MH (Metal Halide) and CMH (Ceramic Metal Halide) bulb, which need an electronic or magnetic ballast to function. We also have CFL lights, Compact Fluorescent Lamps, which contain mercury vapor and inert gas, and they don’t need a ballast to turn on and light up.
When choosing the right bulb for you, it’s incredibly important that you know the type of growing each one is designed for. Some bulbs are for growing, some are for flowering and some are for both. We’re going to have a look at low pressure and high pressure discharge lamps.
High Pressure Discharge Lamps
This type of lamp is designed for the growth period due to its 4000k light spectrum, which is a whiter, colder color. These lamps cause cannabis plants to grow much more compact and leafy, growing shorter internodes and thicker branches. They’re perfect for maintaining mother plants and for your plants’ normal growth period.
High pressure sodium lamps are designed for both the growth and flowering periods based on their light spectrum. They produce a spectrum lower than 6000k, which is a warm light that’s similar to autumn light, which stimulates plant flowering. When growing using these lights you’ll get the best results if you use a specific bulb for the growth and another for flowering. Their mixed spectrum bulbs are also quite efficient.
CMH or LEC lights are kind of like the evolved version of high pressure discharge lights. These types of lights are known for containing different types of gas than HPS and MH lights, offering better results and more professional yields. They also come with a different thread than other bulbs which is much more secure and connects better. They come in all types of different light spectrums; growth, flowering and mixed spectrums. They hardly generate any heat at all, and they provide a high gram/watt ratio.
Low Pressure Discharge Lamps
There are CFL lamps for the growth period (+6000K), for the flowering period (-3000K) and mixed spectrum bulbs (between 6400k and 2700k), although the mixed bulbs aren’t the best choice you could make. However, these lights are perfect for backing up your stronger lights, for maintaining mother plants, rooting clones, germinating seeds and for growing cannabis in small areas. They’re also great if your grow room tends to get much too hot or for using during the summer, although keep in mind that they don’t provide the best results.
Fluorescent tubes work in the exact same way as CFL lights, although instead of being full compact tubes, they’re individual tubes that can be placed on the one panel, allowing you to make a fully personalized lighting system. They’re similar to CFL lights, although they offer a more balanced light distribution. They’re perfect for germinating, rooting clones and for the first few weeks of the growth period.
Grow Lights for Weed | LED lamps
LED lighting has been around for a few decades now, and around 20 years ago it began to be used for growing cannabis. Years ago, LED lights weren’t that good and didn’t provide satisfactory results when growing cannabis, as we didn’t know enough about light spectrums and how to incorporate them into LED lights. However, the fact that they were so light-efficient and didn’t need much electricity caused a certain interest that lead to further investigations.
Nowadays they have perfected LED lighting, especially their potency and light efficiency, and you can find loads of different models on the market for growing cannabis indoors. These lights are for real pros, offering perfect light spectrums while also hardly generating any heat at all.
LED lamps can come in many shapes and sizes; there are some with just a few powerful LED lights and others that contain an enormous amount of less potent LEDS. All of this depends on the design, quality and strength of the LED system. It can be a bit tricky to figure out which one of the best for you, especially due to the fact that new devices and systems are constantly coming on to the market. Many LED devices become obsolete thanks to all of the new models.
Depending on the type of LED that you choose, you can modify their spectrum to either cater to growing or flowering plants, or for both periods. One of the best thing about growing with LED lights is the fact that you can modify their spectrum from the system or using an app on your phone without having to switch out the bulb at all.
As you can probably tell, there are an enormous amount of lights designed for growing plants indoors, all of which have their pros and cons. Hopefully, after reading this article you have a much better idea of the type of bulb you need and why you need it – go check out our lamp section on our online page to get your grow lights for weed!
