Rrog, you wouldn't make a very good hydo store employee or owner..............there has to be something you buy? liquid karma, kelp, humics, castings, rock dust?I have grown to hate the word "fert." Organic fert, chem fert, blah blah. Considering the ease and performance of naturally amended soil, and the ability to recycle it, I am still amazed by people's desire to spend money on ferts, drops, flushes, etc.
