I really don't, it's my first priority. However my second priority is how jealous I am of all the HPS growers out there. Sure my CFLs do everything I expected, and if I could stop following amazing grows I might not have the HPS itch. My cabinet is narrow and I can squeeze a 150 in there but only with inches to spare around the hood, it won't touch but it will be 1.5" away on one side. So my question is.... Will it catch my cabinet on fire?
