best grow bulb for 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.

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.

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.

Ventilation.

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.

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.

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

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.

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.

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.

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.

Safety.

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.

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.

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.

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.

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.

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.

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

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.

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

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.

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

Short for light-emitting diode, an LED is a simple form of light with an efficient energy signature. Due to how the light is generated within an LED, they use a meager amount of electricity for the same amount of light compared to other sources.

● Only useful for small grows.

● You can use them in a small grow space.

For the early vegetative stage, the blue glow from the metal halide lights is best.

Fluorescent lights also don’t require a ridiculous variety of different lights like HID lights.

High-Pressure Sodium Grow Lights.

HID grow lights, short for High-Intensity Discharge, are large light bulbs that emit a tremendous amount of heat and light. They usually require a full exhaust fan to remove the excess heat, and electricity consumption is enormous. Also, they generally need a decent amount of time and space to set up a properly working system.

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

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.

The uninitiated may believe that house lights are sufficient for cannabis plants. However, even if you use LED lighting, it is almost certainly too weak to help a marijuana crop in a grow room. Remember, your home’s lights are designed for your eyes rather than plants. The light spectrum required to help us see is very different from what plants require for photosynthesis.

● Creates less heat compared to other lights.

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

Metal Halide or MH grow lights are primarily used during the vegetative stage . This is the part of the cannabis plant’s life where growth takes off and leaves begin to flourish. MH lights produce a strongly blue-tinged light, which the plants prefer at this stage of growth.

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

● Every bulb needs a socket.

Metal Halide Grow Lights.

This article provides a handy list of some of the best marijuana grow lights for indoor weed currently available on the market. Some of them are cheap; others are a little pricier. Regardless, if you use them correctly, they’ll get the job done.

Yes. However, a plant’s LED light power requirements change during the growth cycle. As your plants get larger, they’ll need a high-powered LED to thrive. The standard LED bulb that works during the first few weeks of growth is insufficient in the flowering stage.

However, fluorescent lighting provides lower yields than its rivals. You must also position them close to your plants to derive any benefit. This means you can use them in a small room , but they are ineffective if you plan to grow several plants.

● Some manufacturers make dubious claims as to the strength of their lighting.

● You need multiple types of HID grow lights for different stages of growth.

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.

HID Grow Lights – The Traditional, Energy Hungry Choice.

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.

It might sound strange that a plant prefers a type of light. However, different colored lights are mostly just different wavelengths and intensities. Due to this difference in wavelength, the plant prefers stronger or weaker lights at various stages of its development.

These days, cannabis growers are spoiled for choice with grow lights. There is an incredible array of options, providing better safety, cost-effectiveness, and efficiency than ever before. Simply put, if you want a decent yield, you must invest in specific marijuana grow lights.

HID Lights are typically divided into a few different varieties or sub-categories:

It isn’t easy to give a reliable estimate since there are several light options, and you need different lighting depending on the stage of growth. In general, you might pay close to $300 for a standard 1000W HID grow light, while a 630W LED light could cost over $1,500.

● You need to replace the bulbs regularly.

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.

CFL grow lights are the twisty-looking bulbs you can find anywhere you normally buy light bulbs. They produce a great spectrum for growing cannabis and can be used in tiny spaces where no other grow light would fit such as the inside of a cabinet.

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.

HIDs are very well suited to growing cannabis and very easy to use once they’re set up. If your main goal is to get the highest yields possible, then HIDs are the way to go! However, they do require extra setup compared to the other grow lights because chances are you will need a fan to vent out heat from your grow space.

2.) High Intensity Discharge (HID) Grow Lights.

CFL Grow Lights.

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.

Metal Halide (MH) Grow Lights.

High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.

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.

3 Main Classes of Marijuana Grow Lights.

3.) LED Grow Lights.

Full tutorial on CMH / LEC grow lights (LEC stands for “Light Emitting Ceramic” and is a type of Metal Halide bulb that is built with ceramic like an HPS – basically it’s sort of like a blend between MH and HPS bulbs)

HID grow lights are much more efficient than fluorescent lights and are powered by large, oddly-shaped bulbs. They are usually screwed into a reflector or hood to reflect more light down onto the plants. HIDs are great at growing cannabis, but they also get very hot and are usually hooked up to an exhaust to help vent out heat.

1.) Fluorescent Grow Lights.

Cannabis plants under a T5 grow light – when plants are trained (like these ones in a Scrog setup) you can get pretty decent yields from fluorescents.

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

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!
