Hope all goes well with it!hyp3rcrav3 said:I got a little tiny piece of HC in a 'R.A.O.K. - Plant It Forward' package. It didn't do we'll in the course gravel since there was so little of it, so I have put the segments in a vivarium. I will let them grow out there and then slowly acclimate to submersed. Should take a year maybe 2. It is a challenge.
