After obtaining an ACMPR license and setting up the indoor grow room, now what? The best course of action is to choose a lighting system to maximize yield. This article discusses HID grow lights for indoor growing environments.
High-intensity discharge (HID) are the cannabis grow lights of choice for many cannabis growers. They produce high yields and can be used at any stage in your cannabis plant’s life cycle, making them versatile cannabis lights! HID’s might not be as popular these days, but they still pack a punch when it comes to growing cannabis indoors.
HIDs are popular cannabis grow lights for seedlings, clones, and mature cannabis plants. HID stands for High-Intensity Discharge, which means that this grow light runs on a particular technology type. HID cannabis grow lights are often used in the vegetative stage because cannabis plants grow very healthy and robust under HID cannabis light.
HIDs are also popular cannabis lights for the flowering stage because they produce high yields indoors, even when compared to other cannabis grow lights like LED cannabis grow lights or CFLs. The best HID cannabis grow lights can be purchased at popular online retailers, featuring trusted brands such as GalaxyHydro Lights, Black Dog LED Grow Lamps, Apollo Horticulture Lighting & many more!

What are HID grow lights?
HID lights are standard and a popular type of grow light. HIDs can come in a variety of forms: metal halide (MH), high-pressure sodium (HPS), or double-ended cannabis bulbs (DE). Each has its specific purpose, though many growers use MH/HPS for vegging and flowering cannabis plants. The cannabis bulb is often used during the final stretch before harvest time because it produces an extra resin that will add to your bud weight. Metal Halide lamps emit a blue light spectrum, while high-pressure sodium lamps have a red color spectrum. We advise using one lamp per growing area if you’re looking to achieve symmetry between each plant as far as coloring goes. Because cannabis plants need a minimum of 12 hours of darkness to initiate the flowering process, make sure you allow HID cannabis grow lights to remain turned off for at least eight hours every night.
What are HID lights suitable for?
HID lights are an excellent choice for growers who need the maximum yield from their plants. HIDs offer several advantages over other types of grow light and have some disadvantages that must be considered when choosing HIDs as your cannabis lighting solution.
HID stands for High-Intensity Discharge
- Produce more lumens per watt than any other type of grow light available today
- Bulbs can be used to replace existing fluorescent lighting in an indoor garden setup with relative ease and little cost involved.
- Come in many different varieties: Mh ( metal halide), Hi-Pressure Sodium (HPS), and Ceramic Metal Halides, which is just another name for CMHs or Copper Halides
- Produce a lot of heat and can be challenging to air cool in some setups. It is vital that HID lighting is placed far enough away from plants so that the lights do not burn them
- Require more electricity than other types of grow light. Still, their high intensity compared with fluorescent bulbs can penetrate deep into the plant canopy where lower lumens levels cannot quickly go. This results in higher yields during the flowering stage.
- The best HIDs for cannabis will include Mh ( metal halide) or Hi-Pressure Sodium (HPS). CMHS/Copper Halides also fall into this category, as does any bulb designed specifically for growing cannabis.
Why should you use a timer with your grow lights?
A timer is a grow light accessory that can help you save money and energy. Instead of using your grow lights 24/365, only use them when needed for 12 hours in the day. This way, you will pay less on electricity bills while having a sustainable grow room environment to provide optimal growth conditions for cannabis plants.
- A grow light timer costs under $20, which could end up saving growers hundreds throughout their grow room project. – The best part is that these accessories are easy to find online or at local stores. When shopping, make sure it has an inline cord switch feature, so there is no concern with manually turning lights on and off.
- Grow light timers can help you save hundreds of dollars over time, so it is an accessory that should be considered if yours did not come with a grow light timer already installed.
- Additionally, grow light timers are easy to find online or at your local hardware stores like Lowes or Home Depot! When shopping for them, make sure the one you choose has an inline cord switch feature since this will mean no need to worry about shutting grow lights off by hand anymore.
What is the importance of light spectrum and intensity when choosing to grow lights for cannabis?
When choosing to grow lights for cannabis, it is vital to consider the light spectrum and intensity. This article will explore some of these concepts explicitly related to growing marijuana indoors with grow lights.
- Grow lights: The first thing that needs clarification when discussing grow lights for indoor cultivation of cannabis is what precisely a “grow light” actually is. A grow light may also be known as a horticultural lamp or high-performance lamp (HPL). These lamps are designed primarily for greenhouses and other controlled environment agriculture where plants require specialized lighting conditions specific to their growth stage. Results cannot always be achieved by natural sunlight alone due to seasonality, area, and weather. In other words, grow lights replace or augment sunlight for growing plants indoors under artificial conditions.
- Light spectrum: The color of the light emitted from grow lamps is measured by its wavelength using nanometers (nm). For example, a grow lamp that emits mostly red-colored light would have a peak wavelength around 630 nm, while one with an output dominantly consisting of blue colors would be closer to 450 nm. Cannabis plants require both types of wavelengths but different amounts depending on their growth stage. It’s essential that grow lights emit balanced ratios across all visible wavelengths instead of favoring any single band to maximize plant yield and quality without compromising vegetative development. In addition, research has shown that specific wavelengths may also be more effective at certain stages of plant development. For example, light in the range between 400-500 nm has been shown to promote flowering, while light in the 500-600nm range is better for promoting photosynthesis during growth.
- Grow light intensity: The amount of energy or photons emitted by grow lamps is measured by its irradiance using watts per square meter (W/m²). Intensity refers to how much usable light reaches plants within a given area and can significantly impact their yield, especially when combined with proper spectral wavelengths. Different grow lamps will emit different amounts of power, so you’ll need to do some research accordingly if you’re looking into buying new equipment but keep in mind that even though grow lamps produce a lot of light, not all grow lights are created equally. In this regard, some are more effective than others when used for growing marijuana indoors.
Tips on how to get optimal results out of your HID grow lights
HID grow lights can be expensive, and not all of the features may seem helpful. Learn how to get optimal performance out of your HID grow light purchase:
- Ensure proper ventilation with a carbon scrubber can increase overall plant health while decreasing the risk of mold developing.
- Use an air conditioning system or evaporative cooling system during periods where high heat levels may result in higher yields.
- Check that there are no light leakages in your grow room; you can ensure that the HID bulbs are focused on where they need to be most.
- Buy a reflector that is designed explicitly for hid lighting.
- Use an appropriate wattage based on plant size and type (see below) in combination with the right sized bulb (e.g., 250W HPS = 18″. You would need a fixture/bulb combo capable of delivering at least 13000 lumens).
- Get good ventilation going before you turn it on; otherwise, heat will build up quickly and kill your plants! If needed, add fans to keep temperatures down when growing cannabis.
- Set up timers for your hid lights.
- Use a combination of high, medium, and low wattage bulbs during different growth stages to get the best yields from your plants. Halogen or CFL lamps are suitable for seedlings, while an HPS is better suited for maturing/flowering plants.
- Experiment with mix & match lighting options HID + (e.g., MH + HPS) until you find out what works best in strength /plant size, bud development time frame, etc.)
- Monitor humidity levels and temperature throughout each day to ensure they remain within optimal ranges; otherwise, plant growth can be disrupted along with yield production!
Things to consider before buying new HID lights for weed
Tips for buying hid grow lights:
- Be sure you know how to use them properly before purchase. Have a professional walk you through the process if necessary.
- Ensure they are compatible with your space and that there is enough ventilation in place. As always, ask an expert for advice!
- Consider what type of growth cycle you’re going to be using – some models work better than others depending on the plant stage at the time of light exposure (veg vs. bloom). Ask the experts about this one, too, though.
Tips on how to make your indoor grow space more efficient with HID lighting
HID lighting is the most common indoor grow light type. It stands for high-intensity discharge and includes metal halide (MH) and high-pressure sodium (HPS). These types of lights will not only help you increase your yields, but they can also be more efficient than other indoor grow light options such as CFLs or fluorescent tubes, which require a larger wattage to emit less light compared to HIDs.
- MH vs. HPS: Metal Halides offer bluish-white color spectrums while High-Pressure Sodium offers reddish-orange spectrum colors – both are used in full-spectrum indoor growing systems
- When to use MH vs. HPS indoor grow lights: during the vegetative stage, you will want a bluish-white light spectrum, whereas when it comes time for your plants to flower, they need red, orange colors – therefore, High-Pressure Sodium is recommended.
- Learn how to adjust lighting cycles and complete each phase of growth successfully by using both Metal Halide (MH) or High-Pressure Sodium (HPS). Changing light cycles can be done via switching out bulbs every few months with specific color spectrums needed at different plant life stages.
- Complete indoor grow systems also include efficient cooling equipment such as carbon filters which cleanse the air through filtering odors caused by humid environments associated with marijuana indoors. UVB replacement bulbs that emit the same wavelengths of light will also offer indoor growers healthy plant lighting.
