plz help

hi every1,im about to start my growing experiance,but theres a few things i need to figure out. first of all i have space in my celler to build a grow room, but im not sure if i have enough height. length n width are ok,but i only have 1.8 mts/6foot, 2inch.my planned setup is.... an Atami Wilma Hydroponic Dripper 8 Plant System(hydroponics setup), Sun System VII 800 Watt Super Spectrum light. i will be ventilating out of celler.so how big will my grow need to be and is that light ok for that height. thanks

You probably want 4+ feet above the dripper system.
I had a hard time seeing the light. but it looks like it has 2 400w bulbs,(800w), but it only uses 1 400w bulb at a time. So $400 dollars seems expensive.

no you can use 1 or the other and both at same time,so you get both ends of the light spectrum.thanks tho
