The system is user-friendly and designed to be used straight out of the box. Simply plug it into an available wall socket, and it is good to go. The GRW also comes with a lens to help concentrate the light downwards to maximize the light source and better benefit your plants.
As you can see, lights for growing weed can be complex – especially when you need to grow multiple plants or use photoperiod plants. You may have also noticed that many of the top 10 lights are LEDs, and it’s no surprise. LEDs offer superior energy efficiency, varied light spectrums, and a long life. Indoor growers of all experience levels know how well LEDs perform, which is why we offer a Light for Pot – Single Pot 75 Watt LED Grow Light in the Pot for Pot shop for those that choose to grow indoors. We also strongly recommend growing auto-flowers.
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.
3. Advanced Platinum Series Grow Light
Harvest up to a pound
The fluorescent light tubes are also two feet long, so the four 24W tubes each provide double the amount of light that you can get from ordinary lights. The T5 is suspended from two points, making it easy to install or adjust relative to the size of your plants. This light system works very well for larger gardens because of how much space a single light can cover.
9. G8LED Mega LED Grow Light
Grow with the Sun
As a general rule, however, CFLs produce the least amount of light, so these lights are best used for germinating or producing clones.
3.) LED 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)
More Light = Bigger Yields!
(up to a point, it is possible to give your plant too much light!)
Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags. Even a lot of LEDs are cheaper and you’ll get better results with them. You can learn more about induction grow lights here.
Example of MH/HPS Setups That Yield 1-5 Ounces/Month
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
There is a larger size MH/HPS grow light available (1000W), but at that size it starts going outside the scope of a “hobbyist” grower as far as ease and yields. In addition to needing a lot of extra cooling which costs electricity, a 1000W HPS grow light is less efficient compared to a 600W grow light (as far as how much light is put out for electricity used). I think most hobbyist growers would be happier with a 600W, or even two 600W lights, over a 1000W
