Rhizome tells the truth about cooltubes being a pita to clean .
I ended up using a furnace filter over my air intake for mine . But I love em . I can get up to 6in away from plants once they're adults w/o bleaching or heat issues . Before buying a digi ballast do some research on them - when they first came out I heard you cant use just any bulbs in them , bulb life issues ?
Peace
