There is it! Finally my first cattleya opened the first bud! I got this plant in Januaru and te plant was in very poor condition then (rooten roots, wrinkled pseudobulbs). uring the summer, It grew 5 new pseudobulbs and few weeks ago I saw 4 spikes growing from those new growths. I removed 2 spikes just to make the blooming easier for the plant.
The time from sheet to opened bloom varies, it depends on temperature. In my case, under optimal temperature plant needed a month to grow 2 spikes and open the flowers.
