Great. I wonder why these are not standard for any grow op. I am thinking that having a 1000W light without a cool tube would just create so much heat and not only make it hard to grow but also hard to stay below the radar of the enemy.
Iscandar Reviewed by Iscandar on . Cool Tube lights and heat signature Hello, I don't know much about cool tubes but it sounds like a great concept. I found some for sale on various websites but don't really know how they work. I saw some duct tube attach to one side of the cool tube. I am guessing that it connects to a fan. Does the other side have ducting attached and what is it for? Also I was interested in the 1000W cool tube light. How serious is the heat signature on something like that? Rating: 5
