  1. The crystals only appear on the undersides of the leaves and as yet not at all on the new leaves. With the information here I am leaning to think the environmental change from the humidity changing from a varying 40% to 75 % in the greenhouse, depending on the time of day, to a constant 90% in the terrarium being the cause since the new leaves grew in this higher humidity and the older leaves growing at the lower humidity and then being moved to the new environment.
  2. These pictures do look very much like the issue with the seedling I originally brought up this issue about. As a follow up , when I returned the plant to the terrarium after washing the crystals off the leaves, the crystals again are forming on the bottom of the same (now older leaves). The newer two leaves are now larger than the original two leaves so the plants certainly seems happier than it was in the greenhouse. The two new leaves do not yet have these crystals forming on them. If it were due to any insect involvement you would expect it to occur on the new softer tissue of the new leaves not reoccurring on the older more hardened off tissue of the old leaves. Probably not due to insects!?

  4. Thank you for your thoughts on this I am somewhat reassured and have put the plant back in the terrarium-like enclosure that it developed the issue in as it seems to be happy in that it grew the 2 new leaves. I had rubbed of and washed the undersides of the leaves right away and so no longer have the material to look at under a magnifying lens but if it occurs again I will not freakout so quickly and will look at it more closely and perhaps take a close-up picture. Because of the rather large orchid collection I have I was of course VERY concerned if it was a pest as treating the entire greenhouse for scale is an onerous task and one I like to avoid. Thanks again for you reply
  5. ? I got a Myrmecodia tuberosa seedling a few months ago (2 leaves , cadex 2 cm in diameter, tiny white spots on the leaves), put it in my greenhouse and it did not progress No new leaves , cadex did not grow. I mainly grow orchids and these spots did not look like any scale I have ever seen. I put it in a terrarium and it grew two new leaves right away but produced MANY crystal-like /gelatinous looking things on the lower surface of the old leaves( enough to totally cover the leaf). The friend I got it from says this is false scale , not anything to worry about and a sign it likes the new conditions. Can anyone comment on false scale? Does this sound like it and if this as an actual a real thing?
  6. I see the plants all orient towards the same direction I wondered what that was
