Well, I got what I think are true Marimo balls about a month ago. They are already sending off little tufts to multiply, and those tufts could easily be mistaken for regular hair algae. Sometimes I wonder how much difference there actually is.
You guys can laugh all you want but when I first started many many moons ago before I got my plant/CO2/fert balance sort of right I had the prettiest patch of that stuff.
I thought it was pretty (yeah I was a total newb!) so I let it grow for a bit on top of a statue as "hair" yeah I can hear you all laughin'
Finally figured out it wasn't some great new plant so I twirled it up and put it where it belonged!! But for a while there the budda lady in my avatar had a hair algae hat!
Swore I wasn't going to tell anybody that....must be gettin' late.
