best grow lights for indoor weed plants

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.

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.

There are many types of lights, but below are the four most common you’ll find in a grow room. There are many variations within each of these four types as well, and new lights and technology come out all the time.

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.

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.

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.

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.

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.

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.

More Light = Bigger Yields!

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: 137W in veg, 255W in flowering (this model has a separate vegetative and flowering mode)

A relatively new name on the scene, Advanced Platinum is selling professional LED grow lights for less money than many other LED lamps of the same quality. Despite the cheaper price tag, they have a wider light spectrum than most LEDs, which helps plants grow faster with fewer of the leaf problems and deficiencies than you see with LED models that only have red and blue diodes. They’re making a good name for themselves in the cannabis growing community because their LED models are getting really great results when it comes to both quality and yields.

Choose LED grow lights if…

Grow Space: Up to 3’x5′ in the vegetative stage, 2’x4′ in the flowering stage

Average Yields: 3.5-4+ ounces – keep in mind that the strain (genetics) and any plant training you do makes a huge difference in your final yields

Kind LED panels have recently been becoming very popular on the cannabis growing scene and seem to be getting great results especially when it comes to yields. However, they are definitely pricey even for LEDs, so that is a big consideration!
