    I have a 5 gallon tank that i want just plants in (to grow and then put in other tanks... So what can i grow with 3w a gallon?can i still grow java moss and java fern and other low light plants?

    3 watts per gallon is typically considered high lighting, however the watts per gallon rule by itself is typically too inaccurate to apply (kind of like the inch per gallon rule for fish). The type of light, intensity of the bulb, height of the tank, clarity of the water and other factors will determine if your lighting is enough. Then other factors such as hardness, temperature and pH would also determine which types of plants you can keep. For a 5 gallon tank, I don't imagine it would be too difficult to really keep any type of plant you want but at 3 watts per gallon you should be fine with java moss and java fern.

    most any plant should grow with that lighting, provided you have proper fertilizer, co2, and good substrate. Java fern and java moss should do fine, I grow both with 2.5 wpg, I would try to put them in the shade of the other plants or maybe somewhere out of direct light.

    the light is pretty high over the tank if that means anything...

    If a lot of the light is not going into the tank it could affect it. Could you lower the light? What type of bulb is it?

    The light being high up over the tank will make a bit of a difference depending just how high it is. I'm afraid the WPG rule doesn't apply to tanks under 10gal so you will actually find yourself restricted on the sorts of plants you can grow. I'm no fan of the wpg rule but basically there is a minimum intensity under which a plant can perform photosythisis. Once you get down around those lighting levels, the tank size becomes irrelevant & all that matters is wether or not the light is intense enough for the plants that you want. 15w of light is a low light tank I'm afraid, regardless of what capacity the tank is. I strongly advise you to get the light you have as low as possible over the tank to maximise the amount of usefull light you have.

    If you lower the light then Java Moss & Java Fern should be fine with your lighting. In addition you could probably do Water Sprite, Water Wisteria, Bolbitis Fern, various Anubius species, most Cryptocoryne species, probably Marimo Moss Balls, Elodea, & perhaps Sunset Hygrophila.

    I'm with Nutter... I can confirm this through my experimentation lol
