i am building a canopy for my 30x30x30 cube.. its 115 gal.... i am installing a 400 watt 6500k iwasaki and i want the rest of the lighting to be super actinic... problem is i can only use 2 foot lights because it is only 30" should i go with 4 vho or 2 vho and two pc.. i am going to be using an icecap 660 so it will power a number of combinations.my goal is more wattage but i like the vho output better than the compacts.. i wanted to to six vho but i can't wire 6 to a 660.. hmmm delima.. any ideas guys?
