At what point do you start using fertilizer and or seaweed on just out of flask phal and phaph seedlings? All are doing just fine the way they are but I would like to give them a little something....Jean
to me light and a high ( 50% plus ) humidity are more important, but generally I fertilise 1x per month with a very weak ( 1/8 ) solution with a high nitrogen number fertiliser. Mine are all in sphag, that makes a difference to what gets accumulated/flushed in the media.
I have lots of seedlings and have just deflasked paph lowii and phals. These will get fertilized in the next go round along with the other seedlings.
