How much are you looking to spend on lighting?
The best would be a 175 watt MH with some PC or
VHO actinics.
But I am sure you could do some PC in a hood and it would be good for a lot of things.
How good are you at DIY or building hoods? This could save you a lot of money on your lighting letting you put more into the ballasts and bulbs.
If you wait until December when I am home, I coule help you build a hood for the tank, you would only have to buy the supplies, I have( my dad) has all the tools needed to build such a thing.
Hope this helps!
