Vandas cost here often more than 20 euros, often around 40 euros.
Richard, I think that is a Ascocentrum, thats family with the vanda (just like musa and ensete)
they love warmth (25-32 degrees) and moist, you don't need to give them fertilize i think.
Your soil is looking like it contains soil. Vandas can even grow without soil etc. *(little bit risky with your seedligns
)
