Good for bulbs for Dwarf Hairgrass?|1

Are 2 of these good for a 20 gallon long? Bought these today, trying to grow dwarf hairgrass.

They should be fine, but you may find that you do not have sufficient spread of lighting with only two CFL bulbs over a 20 gallon long.

what is important is the distance from the substrate and how good your reflector is. if you don't have CO2 I wouldnt recommend having them closer than 15 inches from the substrate

Yes there's going to be co2, it's just in a chicken brooder light that was cheap from lowes. If I need more ill just go back to lowes
