Hello. I was recently gifted a grow light from a friend of mine who also wants to start growing. He bought two of those on accident and gave me his extra. My question is whether or not this light will give me any yield at all? My setup is a 24x24x48in grow tent in my closet. I plan to only grow a single plant for my first attempt at growing MJ. Will this plant be sufficient to grow? If not, can I use it at all throughout my grow? Thank you!
