As more and more states legalize cannabis for cultivation and personal use, interest in growing your own weed at home has never been so high. It comes as no surprise that many people are choosing to grow their own marijuana using indoor hydroponics techniques instead of traditional soil-based methods. This is because hydroponics offers many benefits, such as faster growth, higher yields, fewer pests, and a more discreet way to grow cannabis to its fullest genetic potential. But producing high quality marijuana doesn’t come easy. It starts with a good hydroponics system setup – including the best grow lights for weed.

One of the biggest causes of confusion and disagreement in the world of grow lighting is the word "brightness". The problem is that we constantly use the word colloquially to describe how things "appear" to us – it's a bright sunny day, that bulb is a bit bright, etc. It is no way a scientific definition of light intensity – the number of photons hitting a specific area over time – and ignores wavelengths of light that humans are less sensitive to.
