I have been using (10) Magnum Plus for two years. You want good bud, vegation, growth, this is the the unit. Now the new unit is availabe the magnum plus 2, I can't wait to get these units to try. If you don't think you cann't afford one of these unit, you cann't afford not to buy at least TWO. Save Electicty, Heat, and mental worry that something is wrong in the grow room.
