I wasn't able to find it, but a couple of years back, this guy from Europe wrote in to the APD (Aquatic Plants Digest mailing list) explaining how he was able to grow as many as 3 leaves PER WEEK on each of his Anubias nana plants and with *less than* 1 wpg of lighting (I'm assuming this was normal output, since this was in Europe and was about three years ago). He said that CO2 was the critical factor and he liked injecting it, even in his low-light tanks. He mentioned also being able to grow more light-demanding plants just fine under the same conditions. Just like Tom Barr likes to say: "CO2, CO2, CO2!!!" :biggrin:
