Generally, each plant should be covered by at least 10,000 lumens. So if a standard cheap LED bulb emits 2,500 lumens, 4 or more such bulbs will be needed to grow it. Cheap LEDs come in 15, 26, 42, 65, 68, 85 and 105W versions, although larger models are available.
The goal when buying cheap LED lamps should be to buy the highest wattage (W) possible for the growing space. Generally, more wattage means more power, which in turn means more light, and therefore more food for the plants. To do this, you should know and check the lumens (lm) and understand how they work.
Power and Kelvin Scale
Chances are you have already come across a few discussions on cannabis forums outlining the advantages and disadvantages of the cheap LED lights. Here we are going to make our own selection of pros and cons of this type of lighting.
New growers who are learning and want to experiment without taking risks, will find cheap LED lamps are an economical option for gaining experience with growing. Also for those who want to try growing a plant but don’t want to spend a lot.
How to Choose Cheap LED Marijuana Lights?
Cheap LED lamps are not particularly the most powerful type of lighting available. In this respect, LEC or HPS lights can achieve much more power, nut in a less efficient way.
You can find out much more about light spectrums and grow lights in general in my earlier post.
Both are very important in my book since I don’t like exposing my plants to unnecessary light because it can hurt my yield, and having the ability to daisy-chain multiple units ensures good scaling.

My best advice is to go for an LED grow light because it will save you a lot of cash in the long run. However, if you don’t have the money for one, you can go for either of the two other types. In the next part of the article, I’ve covered all types so you don’t have to worry about exclusion.
Today, I’m going to talk about what you should look for in a grow light if you’re on a tight budget followed by my selection of best cheap grow lights.
What To Look For In A Grow Light?
I also love the design – it features a unique metal body that also acts as a cooling block. The cooling is made even more efficient with the addition of not one, but three cooling fans. These fans run completely silent, which is a huge plus because I can’t stand constant buzzing (and I’m sure you feel the same way).
This is quite a tough decision to make, since all these devices come with a set of unique features and uses.
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.
Metal Halide (MH) Grow Lights
T5s are much bigger/wider than CFLs and usually come as part of a panel, but they can still be kept mere inches away from your plants without worrying about burning them.
Note 2: Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!
Simply hang an LED light over your plants and start growing!
That being said, when it comes to the flowering/budding stage, if you can fit a bigger light you will get significantly better yields/watt by using an HID or LED grow light!
These cannabis plants are thriving under T5 grow lights
