I am growing very young cephalotus seedlings. I use 1/3 sand, 1/3 perlite and 1/3 peat for media. I use 2 pots: a pot with media and holes and this pot is inside another pot with a little water so it can hold a little water for high humidity. I put the pot in low light now for few days then move it to high light after. Never grow young Cephalotus before so welcome all suggestion and comment. Thanks.
