Grow lights are basically electric lights that are used for plant growth. But more than just your everyday light bulb, grow lights are designed to produce an electromagnetic spectrum that will allow your plants to undergo photosynthesis. This allows the plants to grow properly as if it is in a naturally sunny area.

Grow lights are very important especially when it comes to growing plants in areas without natural light. It is also being used in areas where supplemental light is needed. Many of the gardeners that use grow lights live in areas where winters can be quite harsh and daylight hours are too few for plants to grow.

In most cases, the number of watts that you need will depend on how big your grow tent is. Although there are online sources, most experts say that experience will be your best teacher. This is because most calculations, although accurate, they are not actually that precise.

Find the length (L) of the canopy and multiply it by the width (W). Most experts recommend that you provide 50 – 75 watts per square foot with 65 watts being the most ideal depending on what you are growing. You will then have to multiply this by the area (A) to find out how many watts you need.

There are also some experts who recommend that you provide as much as 100 watts per plant. While others recommend that you provide as much as 32 watts per square foot. These suggestions however will work depending on what plant you are growing. Using too much wattage can actually kill the plants.

Using too many watts on your plants on the other hand can actually kill them later on.

Most experts recommend you to try to calculate the area of the canopy first and multiply it by 65 watts so you will know exactly how many watts you need for your entire grow tent. You can also follow the 100 watts per plant or the 32 watts per square foot rule depending on what you prefer.
