The cool tube is by far the best for moving air across the bulb. I made my own batwings using an old hood but I can say the area has never been as cool. LOL just as the name implies. I looked into the batwing reflectors you can buy with the cool tubs but they weren't up to my standard (not wide enough). Much better results with the DIY batwings. Here is a place that has some Grow Light Reflectors, Radiant, Sunspot, Vertizontal
Dogznova Reviewed by Dogznova on . Your favorite enclosed hood My enclosed hood isn't really. It is riveted together and leaks all over the place. The glass panel doesn't seal either. I want a new one, does anyone have a suggestion or favorite? Looking for a small one to hold a 600W HPS, with 6 inch openings. Rating: 5
