I'm doing mine in a mediocrly sunny window, it gets good sun for a few hours, then it's bright shade, then at night it is dimly lit by a fluorescent light. I don't have any LFS (can't keep it alive). The Mama Ceph grows in the same soil as the cutting (except the perlite is replaced with sand), and in a bright windowsill, in 30-40% humidity, has repeated cycles of wet-dry soil. Thank you for your help, I probably could have done a little better but, ah, well, only time will tell if this works out.
