Those aren't really plant bulbs. Also, I would look at getting either 15W or 20W bulbs. These bulbs are in the regular bulb section, and not the fish section.
The LFS I work at uses those flourescent bulbs to light all they tanks even the planted section.
Many of the lfs's that carry the bulbs are usually just 10W bulbs. They are common, but are considered low light. And you really don't need CO2 until you get to the 25W bulbs. I have a non-CO2 tank with 20W bulbs, and it's just fine. But I had to add CO2 to the one with the 25W bulbs.
