The LFS I work at uses those flourescent bulbs to light all they tanks even the planted section.Lonewolfblue said:Check at Walmart. I hear some are starting to carry the GE screw-in CF bulbs that are 6500k. Just make sure the package says that they are either 6500k or 6700k, and not the 3000k. 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.
