You need potassium? Fuck the bananas, gooi potassium! Need nitrogen? Gooi calcuim nitrate! Need anything your plants lacking?
.... OK would I buy this and mix it in the water like the ghe. Or do I extract from the banana. I really like the compost system coz I been mixing up kitchen off cuts. And I feel the result is OK. However if I know what to mix in that it would benift the grow instead of gooing all the alls in there I'm sure I can improve on my bud... Or maybe my theory is wrong.
