I live in Canada, Quebec city and the cold is already setting in, so I want to keep 4 plants inside. My plants are about 3 to 2 feet tall with width ranging from 2 feet to 1 feet 1/2. I currently have a 1000W LED grow light and was wondering if this will be enough to keep them for the winter inside? or would I need at least another 1000W LED grow light ?
