canuck grower Reviewed by canuck grower on . cool tube for a 1000W HPS questions OK, I absolutely need a cool tube, I do not want to build it myself for security reasons and I have some questions about them: 1 â?? I already have a 1000W HPS kit (Ballast, Reflector and Bulb). Can I still use them with a cool tube kit or do I need to buy a new ballast, reflector and HPS light? 2 â?? How expensive will this be considering the equipment I already have? 3 â?? My reflector covers a area of 5 feet by 5 feet â?¦ Can a cool tube cover the same area? Thanks for the help. Rating: 5
