For a 38g tank that is 36X12X20, would you go with a single 250 watt MH or two 150 watt MHs? I plan to use a retro kit and put it under a canopy with plenty of cooling fans. Currently running one 175W.
I have read a lot about the MH bulbs being pretty direct light and was wondering if two bulbs are better than one. I know two would give me about 50 more watts, but is the added heat worth it.
Thanks.
