I don't know kbo..MG and Peter's are made for consumables and I did not know that either had time released nutes of any kind..
I do however take issue with you dissin my compost.
I may not import Norwegian Kelp (please tell me it's not really imported by FF) but I do use the finest Atlantic Bladderwort and Irish Moss and my worm casting are made In Situ by my own red wriggglers. My fish skins and gury are foul as can be and my fowl dropping are the finest a turkey can produce. My cow crap is collected from Holsteins who drop it right on my shovel AND I piss on my compost as well.
Maybe your taste are more discerning than mine but what the hell I have been smoking cigarettes for decades so I'm betting my buds are pretty well shot. Do you really think with proper flushing that you can tell the diff between sumpin grown in FF products and sumpin grown in MG??
It's not how much you spend on your nutes kbo and I have seen "organic" fertilizer made at more than one location. One company called it "Sludge" and the other company used street sweeping from the city of Boston.
Rock on kbo and remember were just talking shit here but your not a nice guy to tak poorly about my compost. In fact I'm hurt.
I'm gonna take my potato peels and water hyacynths out to the compost heap and think about it. It should be steaming nicely this evening. Just know your nutes!!!!
