Hallo Martin,

Vandas are heavy feeders Try using 20-20-20
half strength twice a week also ocassionaly use super bloom evvery third
or
fourth time at half strenght as well. they should do well under 50% shade
cloth

I don't understand what U mean with 20-20-20? I'm using a "normal"? orchid
fertilizer already. And what is superbloom? I suppose, it's something that
contains some plant hormones? What are the ingredients?

I'll shadow her in the next time.

Greetings,

The number 20-20-20 refer to the main chemical makeup of the fertilizer. The
first number is the amount of nitrogen(growth) the second is
phosphorus(flowers) and the third is potassium(roots) . This example is called
a balanced fertilizer....

IIRC, a balanced fertilizer is one that contains the three basics, NPK.
An unbalanced fertilizer contains only one or two of the three.
The proportions don't matter. A 30-15-30 fertilizer is balanced too.
