Hi Rob,
I learned the hard way that D. adelae does not like direct sun since I lost 
the ones I put in my bog but still have the one that I put in shade with my 
orchids.  ((At least I thought it was the sun, although I can't be certain. 
))  While under lights during winter, all had done just fine.  The one in 
shade is doing "ok," but seems to have diminished in size.   I wonder if our 
summer heat (about 4 - 5  months of 80s and 90s F) is too much for D. 
adelae?     How cold are your winter lows?  I'd like to try outdoors again 
either in a new bog that doesn't get direct sun or underneath a lot of plant 
cover in the sunny bog.
Thanks for your advice.
David
P.S. Anyone in the US have some D. adelae (just a few) that they could part 
with for me to train on again.  I'm willing to send you a shipping box and 
ziplock bags to ship them back to me plus stamps for return postage.
