When I grow in dirt ( organic) almlst never anymore, unless it is organic hydro.
I use blood meal, bone meal, sea bird guano, bat guano , worm castings ,
Of course dirt , pearlite ,azomite , garden lime is a must,also several different types of mycos , powdered and liquid ,
Can't get enough of them, I like sucanat for feeding the Bennie's ,
So folks I am not discounting the benefits of worm castings as a huge benefit because of it's micro activity ,
But it is so low in NPK that it won't feed a plant for very long by itself.
The micros from azomite more than makes up for anything in the worm castings provide and the blood meal is for the nitrogen.
These debates for those that see them as you have been civil for the most part are not done in animosity but are good for the whole growers community to see and form their own opinions if they wish also making I would hope both better more knowledgeable understanding growers ,
Everyone will have their own opinions ,
It's not a matter of what benefits we think we get from such things as worm castings , it is we know it benefits us alot to have them in a organic mix.
We just think it benefits us in different ways.
You think it is mostly a food to feed micro and macro nutrients and I think it is mostly a beneficial colony of good little beasties that benefit the plant by making it much better for the plant to up take nutrients and develop a beneficial colony of good beasties in the soils to help the plants root zone and up take ,
That's the only difference in our opinion and nothing to get upset about.
