Driftwood needs about 4w per gallon of light up in the 5500 - 6000 spectrum, of course with that much light you'll need co2 as well. Also, don't feed your driftwood live feeder twigs, they aren't very nutritious and they can carry disease.
Here are the pictures from my rather Small Driftwood, can someone identify the plant growing out of it, and I also bought 2 other plants can someone identify them too? Thanks!
