I have a 10 gallon tank with 2 of those 50/50 actinic 10000K bulbs. I bought a little pot of Dwarf Hairgrass about a month ago and it hasn't started spreading at all. Am I expecting too much to soon? Oh I didn't have CO2 until today (DIY method), and I add TetraPlant FloraPride every other week or so. Maybe it's user error but I can handle criticism. Thanks.
