Hokay, im gonna say that thats a bad idea... and if you are getting good results, then IDK how. Basic biology tells us that a plant cannot absorb complex molecules and coincidentally cant digest unbroken down foods. This is exactly why earthworms are good, they break down the food for the plant to the point that it can be absorbed. (thats why organic nutrients in hydroponics almost always need a enzyme/bacteria culture to fully be absorbed.)
I'm not trying to say your wrong if it worked, but hey... Im surprised you didnt get a mold/fungus/bacteria problem quick. Rotting things near your plants are never a good thing.
TBH this sounds alot like the guy that was on here pretty recently ranting and raving about putting Rid X in his hydro res, and ended up killing a couple members whole crops. To his defense the rid x might have worked, but not for the reason he thought it did, which to make a long story short killed others plants cause the setting wasnt 100% the same....
But heres ur thread back..... sorry bout the rambling, Adderall got me all wired this morning!
