I use them on all my tanks, plants grow very well and I only add Leaf Zone. Just get the 5600 lights not the 4100, the latter is a bit yellow and not as nice and bright.
55gal with one fixture that holds 2 bulbs, 4ft 80watts. And two fixtures with 4 bulbs total with 160watts, sand substrate and only add liquid Leaf Zone, plants grow huge and forest-like. You really do not need specialty items to grow plants, unless you pick the few plants that actually need it.
