The Dens were just too fragile for my setting. I have yet to get Den seedlings to survive. The roots just don't harden off like the Cattleya, Phals, or Phrags.
I am very excited that my Phrag kovachii seedling is doing fine so far. I hope I don't jinx myself.
Here is a picture. I'll definitely try again but only after I get a better set up for Den seedlings.
I just want to report the seedlings i ordered about 1.5 year ago are doing fine and maturing. Unfortunately a few of the more fragile ones like subacaule and seranicum died then because the seedlings were too small and i only got one of each
I got some more species last month and they are also starting to take off.
