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 HID grow lights at different price points.
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.
Here are a few different CFL grow lights at different price points.
HPS (High-pressure sodium)
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.
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.
As an LED, the 440Watt California Lightworks Solarstorm will work for your plants’ entire lifecycle. The light provides five bands of high PAR (Photosynthetic Active Radiation) from the deepest blue colors to the deepest red colors of light – a rich blend of everything your marijuana plants need.
Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs
3. Advanced Platinum Series Grow Light
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.
Regular incandescent bulbs give off more yellow and orange light, starving leafy plants while they burn them.
8. iPower 600-Watt Light
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.
For all types of cannabis, it is usually a good idea to purchase lighting that has both blue and red light spectrums. With regular plants, it saves you from the hassles and costs associated with changing the lighting to induce flowering. LED lights have a full spectrum of light, so you can use the same lights from seedling to harvest.
Simply hang an LED light over your plants and start growing!
2.) High Intensity Discharge (HID) Grow Lights
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.
If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool
Fluorescent grow lights come in many different shapes and sizes, from twisty bulbs to long tubes. Fluorescents are popular because they make efficient and pleasant lighting for humans, and also work great for herb gardens and other types of low-key indoor gardening without using a lot of electricity.

(most common grow light combination for cannabis)
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.
