Very true but I didn't change the fertilizing or the CO2 and with a longer lighting period my plants perked up. Not talking about a minor change. The Kawagoeanum went from 3" leaves and 6" of healthy stem to 4" leaves with 18" of healthy stem. The hairgrass stand thickened within 2 weeks and was 6" tall when I pulled it out. My hairgrass grows tall when light is low, I still had quite low light. There is a minimum length of day for a given system and I was below that point.
