It depends upon the kind of plants that you are growing. For marijuana growers who wish to grow plants in about 4ft x 4ft space, this is an ideal option but more on the lighting in the next question. This is ideal for someone who is looking for something which isn’t as bright as 1200W but not something as low intensity as 600W - this is the middle ground providing a kind of lighting experience for your plants that is neither too bright nor too dark and your plants get just the right kind of light.
