how in the world did you get the moss to grow that..lush without any excel, liquid ferts, or co2? it's a bloody bush!
and when are you selling your cbs!?
Time. Medium light with short photoperiod to prevent algae. Once you get algae on your moss you're done. 6 hours max. It takes a while tho, the moss grows faster in the beginning when the soil is still leaching ammonia.
