Anguloa eburnum and cliftonii

[Dalachin]

New Anguloas from Ecuagenera: cliftonii and eburnum. Potted them up in a mix of bark and perlite with a small quantity of coconut coir potting soil mix and spagnum- trying for a well-draining terrestrial mix. I think it is too cold to put them outside (45 at night right now) so they are hanging out under the lights.

Any advice for keeping these guys alive?
