    I have some anubias petite that i want to try to grow emersed. I got a CFL that is outputting ~300 umols PAR at the plants. The light is very close. Algae isn't going to be much of an issue i presume so, is the drive for nutrients due to such high light going to kill the plants? I believe anubias prefer shaded conditions than high light... Thanks!

    I guess the biggest risk is that the leaves dry out. As long as you can keep the leaves moist I don't see a problem. If you really think it is too much light you can always apply one or multiple layers of mosquito gauze between the light and the plants to reduce the amount of light;)
