what type of led light is used for growing weed

Power equals poundage, so if you want big yields you’ll need more wattage. Professional LEDs can start at as little as 200 watts, and go up from there. A high-watt light can double the work of several low-watt bulbs.

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.

Ventilation.

The typical homegrower will only need one or two lights. Most states limit grow amounts to 6 or 12 plants, and one or two lights should be plenty for that. If you plan on running two separate rooms, one for vegetative plants and one for flowering plants, you’ll need two lights.

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.

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

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.

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.

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.

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”.

CFL lights for growing weed.

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

When growing outdoors you can harness the power of the sun, but in an indoor environment, sunlight is mimicked through the use of grow light bulbs, which aim to display the same spectrum of light as the sun.

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.

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

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.

Safety.

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.

These bulbs contain mercury and metal halides, produce a blueish light, and are commonly used for vegetative growth. They require a ballast to regulate the current. In the past, ballasts have been big and bulky, but digital ones are now available.

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.

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 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.

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.

Finally, LED lights last longer than HID or CFL bulbs, ensuring many years of good use before they need to be replaced. Traditional cannabis grow lights last for only 20 thousand hours. In contrast, LED bulbs last more than twice as long, for up to 50 thousand, or sometimes even 100 thousand hours. That’s five times the life of HID lights!

It used to be that lighting was one of the most expensive aspects of growing marijuana. A good set of HID or CFS lights could set you back a couple hundred with all the required equipment. Now, thanks to LED lights , cannabis grow lights are much more affordable, making growing cannabis at home much more attainable.

Grow with the Sun.

What are the top lights to grow weed indoor?

With LED cannabis grow lights, this is not the case. Different color LED bulbs give a grower the ability to manipulate the color spectrum, thus allowing you to use the same light setup for both phases of growth. This not only eliminates the need to purchase two different types of lighting setups, but you’re also guaranteed the best results in your plants!

Reduced Water Usage.

Be careful when making any changes to your light setup. Decreasing the space between plant and light too quickly might have detrimental effects. Keep an eye on your plants and take it slow!

Cost is not the only reason to make the switch to LED lights . Experienced growers know that seedlings and plants in the vegetative stage benefit more from blue light, while flowering plants need red light to thrive. Before LEDs, growers would have to purchase two different types of lights: metal halide for the vegetative or blue light stage, and high-pressure sodium bulbs for the final flowering stage.

Those who could not afford a good set of HID lights would resort to CFLs, which, while not as effective during the flowering phase , managed to get the job done most of the time. Often times, these were the only options for growers with smaller operations, or those growing a couple plants for personal use. CFLs have gained some popularity over the years, but they would never be as popular as HID lights, which are trusted by growers all over the world. That is until LED lights entered the picture.

What’s the cheapest way to grow weed indoors.

Seed Coupon Included.

If you are willing to step up the quantity of your grow, that is, really take it to the next level, you should be prepared to spend a little bit more cash. A large scale 350-400 watt LED operation that will outdo the average 600 watts HID lighting system is not going to come cheap. However, a larger LED light setup will still be more cost-effective than an HID setup of the same size.

Online Grow Support.

Another thing to consider is how much money LED cannabis grow lights will save you on your energy bill. HID lights are good at what they do, but the amount of energy they use will cause your energy bills to skyrocket. This not only hurts your pocketbook, but it can also draw unwanted attention in your direction either by a landlord, a nosy neighbor, and/or the police. When people had to keep their marijuana growing activities under wraps, spiking electricity bills often gave them away. While cannabis is legal in more areas now, this does not necessarily mean that you want the whole neighborhood knowing what you are up to.

If you’re a more impatient person, LEDs might not be for you. However, most beginners will benefit from using LED cannabis grow lights. In fact, they might be just the thing you’re looking for! Our LED grow lights can be purchased individually alongside our Complete Grow Kit . A Pot for Pot 75 Watt LED lights are each perfect for a pot with 1.5 sq ft of canopy, and multiple lights can be arranged for a larger grow.

Growing Cannabis Using LED Lights.

If there is one drawback of using LED grow lights, it is that your plants’ grow time will be slower than if you were using HID lights. Again, this is because HIDs emit more energy than LEDs, leading to faster flowering.

You should also be aware that while LEDs don’t put out as much energy, your plants are still susceptible to light burn. So, like any other lights, make sure that you are keeping your lights a proper distance from your plants.

The benefits of using LED cannabis grow lights are many. The next big question is how to grow marijuana using only LED lights. A good rule of thumb is one light per every 1.5 square feet. This generally will yield you up to 6 ounces per plant, which ends up covering what you spend on the light and will definitely end up saving you money in the long run. If you are growing only 1-2 plants, our single 75 watts LED light supplies plenty of light for your plants.

Grow Year Round.

Not only are LED lights more energy-efficient , but you’ll also save on water usage as well. As you are now aware, HID lights use a lot of energy, which in turn produces more heat. This dramatically increases the temperature of the grow room, causing your plants to consume more water. Cannabis is already quite the water hog when compared to other plants and growing even just a small amount of plants uses a lot of water. Any way to reduce water consumption is great for the environment, not to mention great for your utility bill.

Our complete grow kits include everything you need to go from seed to your very own supply of high grade medical cannabis.

Different Types of Cannabis Grow Lights.

This was not always the case. When LEDs were first gaining momentum among growers, the technology was still fairly new and had not entirely been perfected. Think about how expensive and inconvenient cutting-edge technology like smartphones were when they first came out, and it often wasn’t worth it. For example, many agree that the first-generation iPhone was not the greatest. However, today’s smartphones are much more affordable, and they are everywhere.

For many, the main reason is that they are relatively inexpensive when compared to the much pricier HID setup. This is especially true if you are growing a smaller number of plants. Our grow lights at A Pot for Pot are specifically designed for growing a small number of marijuana plants and is priced well under $200 – proof that high-quality lighting doesn’t need to be expensive.

What are the best grow tents to grow weed?

There are many reasons to use LED lights when growing cannabis.

The main types of cannabis grow lights are HID, or high-intensity discharge, CFL or compact fluorescent lights, and of course, LED or light-emitting diode lights. HID lights were the most commonly used cannabis grow lights when indoor growing first became popular in the 1990s. This was because they produced just the right number of lumens to grow cannabis indoors.

Though they work exceptionally well, HID lights are not without issues. For instance, a good setup is very expensive. If your plants don’t produce to your liking, you could find yourself out a few hundred dollars with no way to make your money back.

Harvest up to a pound.

Average Yields: 8-16+ ounces – keep in mind that the strain (genetics) and any plant training you do will make a huge difference in your final yields. This LED model has performed better than most others I’ve tried so far.

These grow lights use huge COB (Chip on Board) LED “bulbs”. Each COB is incredibly bright and intense because they contain multiple LED chips in a small area. COBs produce more intense light than other types of LEDs, and each COB uses a significant amount of electricity. Cree is most popular brand of COBs.

LED grow lights are relatively new to the cannabis growing scene, but they have become wildly popular over the last few years with their ability to produce great yields while staying cool and using a reasonable amount of electricity.

How Far to Keep from Plants : 20-28″ for the vegetative stage. 18-20″ away in the flowering stage.

Actual Power Consumption: 65W.

LEDs vs Other Popular Cannabis Grow Lights.

Introduction – LEDs on average yield 0.5 to 1g/watt (of actual power draw.

How Far to Keep from Plants : 36″ is the recommended starting distance from the plants.

Grow Space: Up to 4′ x 4′ in the vegetative stage. It’s listed to cover between 2.5′ x 2.5′ to 3′ x 3′ in the flowering stage, but the rectangular shape actually makes it perfect for a 2’x4′ grow tent.

Quantum Board.

LED grow lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that’s going to run cooler. Although LED grow lights do produce heat, the smaller models might not bring up the temperature of your grow space.

Average Yields: 5-11+ ounces – keep in mind that the strain (genetics) and any plant training you do makes a huge difference in your final yields.

Generally, your goal with LED panels should be 50-60 watts per square foot of grow space to get the best results.

How Far to Keep from Plants : 24-38″ is the standard starting distance for the vegetative stage. You can move it to 18-20″ away in the flowering stage, or possibly even a few inches closer for light-loving strains.

Actual Power Consumption: 500W at full power, and can be dimmed down to 200W for younger plants.

It’s also common to see LED grow lights that only have one COB per lamp. These make it easy to spread out your light over a grow area, one lamp at a time. Sometimes known as “AutoCOBs”.
