Compost from scraps

also, does ewc count as brown? or green?

Trust me, you won't get away with this in hydroton if you intend doing it in any form of hydroponics. I have tried as ebb and flow and it doesn't work. I suspect it's just as you can't get all the macro/micro nutes at the correct levels. You need soil as a buffer.

Yes. All of this is great for excellent soil. If you're doing some hydro / pumping who knows. I really encourage anyone too look at soil. Simpler, better, cheaper.

That would be a whole different thread Rrog! Personally, I disagree but see advantages and disadvantages in both (and currently do both in different situations). Bit like comparing Apples and Oranges.

I would take either the apple or the orange, whichever was grown naturally

I would take the largest. Many would take the cheapest or easiest

Ha! Then soil wins again! Sorry... couldn't help myself. Peace. Anyway, back to our regularly scheduled program
