well... not the first one, but the first Cattleya
my first plants were some Paph NOIDs I picked at the supermarket, in order to test the system (which I did not trust at the beginning

)... it went very well, then I tried my first Phals, which adapted very well too... Then I decided to go for the catts & others... they are bit trickier... and I was worried at the beginning... especially after loosing Hexisea bidentata (did not like S/H at all

- and I have not been able to replace the plant)
