How long before KLN leaves an orchids system?

Root stimulating additives - synthetic ones like Dyna-Gro K-L-N, or SuperThrive, and natural seaweed extracts like KelpMax - are best used as an additive to your feeding program, so are simply added to your irrigation solution on a periodic basis, and used to drench the medium.

Ray,

What would 'periodic' mean? Once a week, month?

I am using a product called Kelpak 2T/gal once a month. I'm seeing good results but I feel like I'm shooting in the dark as far as amount and frequency.
