Dends Grow Faster Than Phals?

[dianecty]

Hi! In April, when I bought the dends, they were about 3 1/2" tall, now they are 6-9" tall! However, my phals - some of them are still the same size 1" or maybe 2" tall now. So they only gained 1".

Is it true that phals grow much slower than dends? Is this the normal growth rate for both orchids?

My dends are fat too and have a lot of little growths coming out. I think the KLN is more effective in dends than phals. Do you think so?
