hello, i got a piece of driftwood with riccia pre-attatched to it:
i had actually been looking at riccia and driftwood here and on ebay, so i was happy to find both.
anyway, i was wondering about its growth rate, about how long from now should i expect to see that piece covered?
and will it spread to the ground, i really like the carpeted look.
btw, no CO2, no fertilizers as of right now, but about 3 WPG
