This is a very helpful discussion and one of the main reasons I love this forum.
Since most of my orchids ore in semi hydro I understand from Jerry that I don't need the fertilizer with the higher nitrogen for most of my orchids. However, if I understand correctly the nitrogen is what encourages growth, so is it better to use the higher nitrogen for my "baby" orchids? By "baby" I mean the ones that are not blooming size yet. (I have a lot of these due to my husband's E-Bay addiction.) Lashelle
