Nice job with the hybrid! I'm curious about the veitchiana. What temperatures was it in when the leaf drop started happening? I have mine double potted in clay with sphagnum and perlite but I'm not sure how it would fare in my 80 degree F + summer temperatures. Also, is ignea more sensitive to temperature than vietchiana? I was told from one report that they live in similar areas but another said it is more heat sensitive.
