    Not how you calculate it, but how do you find out how many watts your bulb is? My (fluorescent) light just came with the hood, and all I can find anywhere is that it's 24". ???

    It should be on the bulb itself - you may have to spin it.

    Oh, DUH...would you look at that, 17 watts, right on there! ::) So I guess that makes my wpg a little less than 1. That should be fine for low-light plants, shouldn't it? Can you get bulbs the same length but higher wattage?

    Are you sure it's a 24" bulb because mine is a 24" bulb and I have two and they are both 20w. A simple answer to your question, NO unless you change or make your own fixture. You can buy strip lights with compact fluescent bulbs or twin tube or get special lights that hang over your tank from special fixtures that are special for plants but they are expensive. Unless you want to spend a fair amount of money, probably 50$+ you can't change your lights. You can get reflectors to focus your light though.

    Well it said 17W. Too bad you can't get bulbs with higher wattage. I don't exactly have heaps of money sittin around... :p

    Me either, the best thing to do is buy a incidescent hood and replace the bulbs with 10w compact fluescent, probably your cheapest way.

    well, I'm not gonna worry about it, I've just got low-light plants.

    It should say a higher wattage on the hood itself. What brand is it? From what I've seen the bulbs that come standard are fairly low-watt. I have a 32watt on my 55gallon and my Java Fern is growing ridiculously fast. Actually, it's more of a bush right now. I also have some swords and some floating plants which are doing quite well.
