It is roughly 20-23 cm tall. I grow it in the same greenhouse with everything else. It is set up for Parvis so very cold in the winter with warmer summers no more than 33C in the summer. The Odonts are mostly all potted in terra-cotta pots and with sphagnum moss. This keeps them cooler just need to make sure the pot does not fully dry. I just started to experiment with rockwool as potting media for cool growers but do not have any good data to share.
