would the (3) 400w be over kill?
I all ways like double ended bulbs
Nothing like a 14k phoenix bulb
if i remember correctly, i had mine 14-16" above the water (from the bulb itself). you don't want any splash on the super hot bulb.....i have seen a bulb exploded when a worker at the lfs accidentally splashed the water on it.
I see that they have 2 types. ( Sun system and hydrofarm ) which 1 did you get?
