Lighting a 20Gallon High.

[ChristinaE12]

Sorry for what appears to be repeated questions...but I actually did research and didn't come up with exactly what I'm asking..

Now onto my questions...

Basically I have a 20 Gallon High that I'm trying to do a planted with. And want to know what will give me high lighting. I am currently running 2-60W T2 CFL's. Which are 6500K.

I do not have a CO2 system and don't know when I will be able to.

I'm wondering if this is actually overkill and too much lighting at this point? Is 1 of these bulbs sufficient. This tank being a "high" is kinda throwing me off as well as the bulbs being CFL's.

I just want to have enough lighting to grow what I want.. Essentially.
