plants seem to be doing all right...

i have a 30gallon planted with only 20watts of light. my plants seem to be doing fine, they have greened up alot since i first got them. i also have new growth on some of them. should i still invest in a higher wattage fixture????

depends on what you want to do in the future. You could monitor their health for the next one-two months. Plants take a while to start showing improvement and I would think after two months you'd know the full affect of your light on the plants.
