I never used Howard "The Dirt Doctor" Garret's Juice. It would have been cost prohibitive on my scale of useage. I corresponded and called his radio show on a fairly regular basis thru the 90s. Info wasn't readily available back then and more so with organics. I didn't miss his radio show back then.I do/it is! I like buying the pre-made GJ as I am space-challenged (among other challenges) and don't want to keep multiple bottles of stuff if I can help it.
My biggest problem back then was upscaling my organic program. It worked well enough to get the Federal Extension Ag agent to come out to my farm and ask why my unirrigated hay pasture looks so green during a drought. LOL!
