Amazing view, David! Thank you for sharing. There are quite a bit of variation in the stage of growth; some are still 1-2cm while others are flowering. Do the pots at the lower shelf contain Cyps, too?
This is my 3rd year of Cyp growing (well 4th, but the first year was a complete failure) after I saw how you grow them. I think you are completely right that the big pots are advantageous. From the same flask, the ones in the big pots have survived better than the smaller pots. But under my condition, a bit more organic materials work better. I think that this is because I'm not watering enough, and organic matters (coco peat) is probably making the moisture more stable.
One interesting thing I found yesterday is that I didn't see any growths with Cyp. guttatum last year. I assumed that it was dead, but I kept watering it with the others. But this year, I found that small shoots are starting. In my climate, most Cyps are still 1cm or so at this moment, and this individual is much smaller (about 1mm sticking out) than the rest, but I'm excited that it wasn't dead!
Could you possibly tell me how you fertilize? I think you told us once, but I can't seem to locate it.
