Growing cannabis plants can be a rewarding experience, but it takes a lot of work to ensure the plants are healthy and thriving. One of the most common issues that growers face is light burn, which can be caused by too much light or by too intense light. In this blog article, we’ll explore what light burn is, the causes of light burn, tips for preventing light burn, and how to help a cannabis plant recover from light burn. So let’s get started.
