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.

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).

Fluorescents are a great choice for clones, young plants, supplemental lighting and can save you money on electricity in the vegetative stage compared to using high power lights when plants are too young to use it all anyway. They can also be used to flower plants in spaces that are shorter than what’s possible with other grow lights (aka ‘stealth growing’).

For growers who are looking to harvest 1/2 to 1 ounce of cannabis a month, LEDs may be your best choice. At this size, they are super low on electricity, run cool and need almost no setup! They get better yields than fluorescents but don’t run as hot as an HPS of similar wattage.

CFL Grow Lights

As a general rule, however, CFLs produce the least amount of light, so these lights are best used for germinating or producing clones.

Wattage also helps determine how far away you should keep your plants. Generally speaking, higher wattage lights need to be positioned further away from your plants because they can burn them. LED lights are an exception to this rule because they give off surprisingly less heat when compared to the other types of lighting with the same wattage.

The downsides of this light are that it is rather noisy and doesn’t include dimming options. However, it still deserves a spot on our top 10 list.

The Lithonia Light GRW is a hanging light that is suitable for both larger indoor weed grow operations as well as small hobby gardens. This is because you can simply adjust the chains to adapt the light system to the evolving size of your plants.
