Can't wait until mine is large enough to eat! It's smaller than a pencil head. I got mine from Planet Zoa during his Live Sale. Was a very small mooshyroom and I had ups and downs with it. Oddly after having no room I had to leave it very high up with my zoas on a magnetic frag rack with low flow but very high light and was slightly worried about it melting from high light. It ended up being the happiest there and I guess it likes high light.
Yeah, the rainbow shroom is my fav pick up this year. Calling it the XTC Shroom.
