This board doesn't permit the promotion/advertizing of specific products/retailers (I stand corrected, BD if I have misspoke) which is cool because then the forum is about the the main ingredient...the orchid and our education and pleasure in sharing. I am currently using a fertilizer that is readily available at a big box store for about $3.85/#. Then there is the issue with some about urea based vs non-urea based...not going there today. Anyway, PM me and I will share more...
