Ok, so from what I have read here and in other nooks of the 'net lights are pretty darn important to plants. So is color and watts (sort of) and k's and PC and T5s and...sheesh. I don't wanna say that I am dumb, but when it comes to lighting, my brain seems to be running a 20 watt incandecent! So let me just ask a couple questions straight out (even though I am sure there is no solid answer to this). Are T5s better than PC? I know they are more expensive initially, but I believe they are more efficient long term. Correct? Also, I know that the old WPG rule is well, old. I have done extensive reading on how to figure the best lighting for a tank, but honestly alot of what I read is above my head (dim bulb of a brain). So...I have a 65 gal tank that is 24 inches tall. Would 4 39 watt bulbs be suffucient to light up my life? I am starting slow and easy but want to buy enough juice now to grow the hard stuff later. Thanks for any help you can give!
