What Gives a Grow Light Charge?

It's important to understand the difference between DP charges and GWh in a grow light system. GWh represents the number of watts used for one hour of sunlight. While it isn't that dissimilar from "watts" the distinction is that GWh takes into account not only the direct amount of light but also indirect rays from sources such as fluorescent lights or lamps. The larger the number of indirect lights, the higher the "GWh" value.

Typically, the higher the GWh value, the more energy you'll need to power your indoor growing environment. How much power you'll use will depend on how much sun you get and what kind of plant material you're growing. For instance, if you're growing an expensive specimen plant you might want to go with a higher GWh value bulb so you'll get more energy for your buck. On the other hand, if you're just starting out, you probably don't need to spend a lot of money on high-end lights. You can get by with a lower rated bulb and save some money. So make sure you understand the difference before purchasing.

As you can see, both GWh and DP charges are important parts of the indoor grow light equation. Just know the differences between them so you know whether or not you need to upgrade your grow lights. It's also helpful to understand the pros and cons of each type of charge. If you need a bigger charge you'll pay for it no matter what and if you need a smaller charge, you'll have to decide if that makes sense for your budget. If you keep these things in mind, you'll be able to choose a grow light system that works right for you.
