best type of grow lights for weed

These fluorescent lights are cheap and efficient and great for vegetative growth. They’re especially great for helping along germinating seeds and small seedlings because they don’t put off much heat and won’t scorch the delicate seeds. They won’t run up your electricity bill too much.

There are daylight bulbs and warm white bulbs; the former better for vegetative growth, and the latter for flowering.

Another consideration with cost is that some lights run hotter than others—HIDs, for example—so they may require additional fans or an AC unit to cool down a grow space. Extra equipment means more electricity, also driving up your utility bill.

Here are a few different CFL grow lights at different price points.

Lights have fixtures and bulbs, and some require a ballast. Depending on the type and model, the bulbs or the fixtures can be more expensive. There are a lot of abbreviations, but don’t be alarmed.

Best HID grow light brands.

For HIDs, light occurs as an arc between two nodes inside the bulb. The gas contained in these bulbs is what makes MHs and HPSs different. HID bulbs are usually more expensive than the reflective hoods that hold them.

Aside from the price of the actual light, also take into account utilities—all lights will add to your electricity bill every month, but some more than others. High-intensity discharge lights—known as “HIDs”—may be cheaper to buy but can gobble up electricity, whereas LEDs are more efficient and kinder on your electricity bill but usually more expensive to buy.

You can find lights for under $100, but they may be low quality and not produce the right spectrum of light, and you can also easily spend as much as $2,000 for a large, state-of-the-art LED.

HID (high-intensity discharge) is an umbrella term under which MH and HPS bulbs fall, which we’ll discuss more below. These types of lamps have a hood that reflects light and bulbs that are enclosed capsules containing a gas, as opposed to bulbs you’d find in your house, which have a filament that heats up.

Fixtures come in all shapes and sizes and can usually accommodate 4-12 long fluorescent bulbs; a standard size is 8 bulbs. Fixtures usually have a reflective material to bounce light in one direction, down on your plants.

Make sure you have enough outlets and power available in your breaker board for your grow space to comfortably accommodate all equipment. Figure out all pieces of equipment, such as lights, fans, possibly an AC or dehumidifier, and calculate how much power they’ll require. You’ll be running this equipment every day for months, so if you don’t have enough power it can be dangerous. Never overload an electrical outlet.

One of the crucial elements a cannabis plant needs is light. During photosynthesis, a plant converts light energy into chemical energy, allowing it to grow strong and healthy, and with cannabis in particular, light also fuels bud production.

There are many different kinds of lights out there, so it can be daunting to know where to begin. Here’s a guide to four basic types of grow lights on the market and the pros and cons of each.

You can find HID reflector hoods, as well as MH and HPS bulbs at any local grow shop.

The first thing to consider before buying a grow light is how much money you want to spend. With more states coming online with adult-use legalization, homegrowing is becoming more popular and growing technology is getting better and more efficient all the time.

HPS (High-pressure sodium)

HIDs have been the standard in indoor weed growing for decades, but LEDs are quickly catching up to them.

Consider how often you’ll be growing weed and how long it will take to pay off the initial investment—if you grow once a year, it’ll take a lot longer to pay off an expensive light than if you grow multiple harvests a year.

These HID bulbs usually contain sodium, mercury, and xenon, and produce a yellow/orange light, and are commonly used for flowering plants. Some growers will start plants under MH bulbs and switch them to HPSs when plants go into the flowering stage, using the same hood. These lights also require a ballast.

New LED grow lights come out all the time, but knockoffs abound. There are a lot of cheap LEDs that don’t produce the right spectrum of light for plants.

Here are a few different HID grow lights at different price points.

The downside to CFLs is they aren’t great for flowering plants, and growers will usually use another type of light to finish plants. CFLs just don’t generate enough intense light for plants to pack on weight.

LEDs also typically run a lot cooler than HIDs, so you may not need extra equipment to cool down your grow space, and one LED can usually be used for both vegetative and flowering growth. Some high-end LEDs allow you to change the spectrum for each growth stage.

Other considerations when choosing a cannabis grow light.

Ventilation is also a concern. If you’re growing in a tight space with a light that runs hot, you’ll need to have fans in there, which also take up space. If there’s not enough room for a light and a fan, you may need to invest in a light that doesn’t run as hot, such as an LED. For example, grow tents are usually built tall to allow room for equipment up top, not to grow plants all the way to the ceiling.

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.

Some grow lights are more expensive than others, but also more efficient, saving money in the long run. Some lights are bulky with many parts, some light in weight, and some are better suited for young or mature plants.

As with HIDs, you can find CFLs at any local grow shop.

However, because of their low price, if you’re new to indoor growing and not sure how often you’ll do it, you may want to invest in an inexpensive HID light at first to test the water.

Grow lights allow you to control exactly how much light your plants receive, ensuring they get the same amount of light day after day, without the grower having to solve problems with bad weather or cloudy days that happen in an outdoor environment.

How big a light you need will depend on the number of plants you plan on growing, but also on the size of your space. If you’re growing in a closet or a small grow tent, you’ll only be able to fit one small light in there. If you have a wide open basement, you could invest in a bigger light as opposed to two smaller ones.

LEDs (light emitting diodes) are relatively new to the cannabis growing world, compared to HPSs, MHs, and CFLs, but they are quickly proving to be the way of the future. LEDs may be more expensive to buy initially, but they are far more efficient and kinder to the environment and your electricity bill. Some cities even give tax breaks to commercial growers who install or switch to LEDs because they’re better for the environment.

How big is your grow room going to be? If you don’t have much space, you should steer clear of ‘hot’ lights, or else the room’s temperature will increase rapidly. You also won’t have enough space to install an AC unit.

● Reduced efficiency and low yields.

● Low electricity usage.

Ventilation.

● They can require large boards of LEDs due to their relatively low power.

You can buy HPS lighting in a variety of strengths, but don’t use 1000W. It is far too powerful and is only suitable if you have created a vast underground field of cannabis plants! Instead, a pair of 400W or 600W HPS lights should suffice.

However, LEDs have a pricing problem. The lights you need for cultivating cannabis are costly. If you try and use the cheap, Christmas-style lights, your weed harvest will be smaller than the LED’s carbon footprint . If you want to invest in your bud correctly, prepare to spend a substantial amount of money.

● They run extremely hot and consume a lot of power.

● Creates less heat compared to other lights.

● Every bulb needs a socket.

Metal Halide Grow Lights.

The choice of whether to use LEC over the standard MH grow light is a personal preference. However, it’s also tied to cost. LEC grow lights represent a higher initial investment. Yet, they also are more efficient over the long haul, lowering your overall electricity bill.

● Incredibly energy efficient, which means a lower energy bill.

One great benefit of LED grow lights is that they create comparatively little heat compared to other types of light.

It is best to calculate how much cannabis you need each year. MMJ patients and regular recreational users are best served making a one-off investment in decent standard lights. Also, the more harvests you intend to have, the quicker you ‘pay off’ the cost of lights. If you only plan to grow cannabis occasionally, HIDs may fit the bill because of their cheaper initial cost.

HID Grow Lights – The Traditional, Energy Hungry Choice.

Yes. Cannabis plants grow naturally in the sun, which provides an incredible amount of light. You need to replicate this light source as much as possible, and this is where marijuana grow lights come in. Apart from providing enough light, they also ensure your plants benefit from the right light spectrums.

● They are the most intense light option available, ensuring your plants get all the light they need.

● Only useful for small grows.

Then again, if you have a grow space of less than five square feet, fluorescent light is enough when your plants are small. You can upgrade to a 250W HPS as the plants get larger. If you have space, an MH light for plants in the vegetative stage and HPS for the blooming phase works well. Using MH lighting throughout is fine but will have fewer flowers, more foliage, and a lower yield.

LED grow lights can also distribute a fuller light spectrum due to how the light is created through electroluminescence. This can result in a better, higher quality yield from your bud.

T5s are much bigger/wider than CFLs and usually come as part of a panel, but they can still be kept mere inches away from your plants without worrying about burning them.

Metal Halide grow lights are generally used for the vegetative stage because they produce a bluish light that vegetative plants love, though this type of light can also be used all the way to harvest.

Note: Some growers may have heard of “Induction” grow lights, which are pretty rare these days but still pop up from time to time. There are two types: “Magnetic Induction” grow lights do okay for growing cannabis but they’re pretty much glorified fluorescent lights. “Plasma Induction” grow lights actually perform pretty poorly at growing cannabis.

Simply hang an LED light over your plants and start growing!

Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights.

Metal Halide (MH) Grow Lights.

T5 Grow Lights.

Pros and Cons of HID Grow Lights.

Keeping CFLs close results in the best yields and growth.

Note 2 : Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!

3 Main Classes of Marijuana Grow Lights.

These are actually just two names for the same thing. This type of metal halide bulb uses ceramic as part of the lamp just like an HPS. As a result, CMH bulbs are more efficient than regular MH lights (though still not as efficient as HPS bulbs).

That being said, when it comes to the flowering/budding stage, if you can fit a bigger light you will get significantly better yields/watt by using an HID or LED grow light!

More Light = Bigger Yields! (up to a point, it is possible to give your plant too much light!)

There are lots of options for grow lights that work well for growing cannabis indoors but in the end they boil down to 3 major types:

3.) LED Grow Lights.

If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool.

“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.

LED grow lights are very popular among cannabis growers as an alternative to HPS grow lights. They tend to run cooler and also usually come with built-in cooling. They can often be plugged into a wall and simply hung over plants which is definitely easier than setting up an HID grow light. LEDs also have great penetration so they don’t need to be moved frequently like fluorescents.

For the many growers who are unable to cultivate cannabis outside in the free abundant sunshine, grow lights are necessary to successfully grow cannabis indoors. Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy cannabis plant won’t produce much bud at all.
