Hello fellow growers! I'm having a doubt regarding my lighting system, I have an 450W HPS light with a cool-tube but my cord is shorter than I thought.. I need to know if it's safe to connect another cord to the one I already have to make it longer and thus making the lights lower. I know this is a noob question but my grow is already in place and for that reason I can't remove the light to replace the cord I have for a longer one. Thanks in advance! Happy growing m8's
