hows it happy grass?

From what the ad says that these t5's are of blue spectrum. The one thing that is best for any indoor plants are of course full spectrum. The best is to shoot for a full spectrum, so if you want to achive the best w/ fluorescents i would find full spectrum t5's. And in case you decide to ad the warm white just keep in mind that you want the lights to mesh, so if you decide to ad them as side lighting ( which side lighting is always a good idea, due to the lack of penetration through the foliage )your going to want to keep them at the same level so they mesh well, this is not a bad thing, due to the fact that it would spred the light coverage.well thats my 2 cents at least.
