I keep telling myself things like this and it adds up and in the end. check my earlier comments. I'm trying to just use the things up that I have. Not trying to spend money where I don't need to. I could get carried away easily.I couldn't imagine going against the grain and risking a no till bed over $30 worth of peat.
Youve been here longer then I have,I remember a few threads of people having problems with this.There was no fixes AFAIK.I keep telling myself things like this and it adds up and in the end. check my earlier comments.

I havent seen any journals or books or real attempts like this with coco online anywhere. But people say it works. At this point I'm willing to challenge that from a full organic standpoint.

I like that you are kind of going off the beaten path. Hopefully you will keep updating and we can all learn a little. I think your use of bio char should help with retaining nutrients along with the basalt, from what I've read at least.I keep telling myself things like this and it adds up and in the end. check my earlier comments.

Funny thing is, ill either have two 5 gal pots or three 3 gal pots going next to this coco bed that will be filled with living soil that is peat based.I like that you are kind of going off the beaten path.

Again just my two cents and good luck.
Edit: worst case scenario you can just mix this batch up with a future peat based mix and it'll all work out down the road.
So your saying make a small batch and check it? I followed BAS recomendations. This is the ratio they recommend for coco. The only thing different between their peat mix is the langbenite vs oyster flour. Oyster flour in the peat, Langbenite in the coco. In those ratios i have listed.Before you mix that up, I'd hold off, there is a lot off with that mix. Way too much langbeinite among other things. Rather than waste the money on all that stuff, calculate out smaller proportions then have it tested. You are going to be through the roof with some of those #s. You may also have a problem with PH as most living soil mixes base their calcium and and other PH stabilizing agents ( like rock dust) on the fact that their base is peat rather than coco. Nothing worse than ending up with a big batch of unusable media that has you chasing nutrient lockouts the entire grow, many of us have been there before.
From what I learned, coco holds alot of K and doesnt release it as fast, Theirfore you must add, not subtract. The slow release is what gets you.What's up with coir and potassium? Does coco release K over time?
And if a coco coir soil will be high in Potassium is it a good idea to use a little less langbienite to keep K in check?
This is what I found on their site. Looks like my math is wrong. You guys are right. Need to use less Langbenite. I'm making adjustsment to the recipe now.Before you mix that up, I'd hold off, there is a lot off with that mix. Way too much langbeinite among other things.

normally special cocos ferts have less K then others.From what I learned, coco holds alot of K and doesnt release it as fast, Theirfore you must add, not subtract. The slow release is what gets you.
I've grown in coco for years witout any issue. But it was using a flood and drain setup with jacks 3 2 1 style.

So you're saying more Mg and Ca with less K gives the balance in coco. Interesting. Well I've adjusted the langbeinite to 8 tablespoons. Heres the updated list:normally special cocos ferts have less K then others.
to my understanding cocos holds a lot K allready (or worse, NaCl), when there is a higher concentration of molecules with 2 charges like Mg or Ca, Mg or Ca are replacing the K or NaCl which gets released then.
How would one buffer coco before using in organic living soil build?see here.

Why You Need to Buffer Coco Coir
There are cation exchange sites in coco that will interfere with nutrition until they are buffered. The cation exchange sites in coco naturally come loaded with sodium (Na) and potassium (K) cations. However, the Na and the K are only weakly held to the exchange sites. In the presence of calcium (Ca) or magnesium (Mg), the sites will release their Na or K cations and lock onto the Ca or Mg. These processes are known as “cation exchanges”.
Buffering coco is accomplished by soaking it in Ca and Mg. This allows the cation exchanges to take place prior to adding plants. Simply soak your coco in a solution of Cal/Mag water and the exchange sites will release their K and Na cations and lock onto the Ca and Mg. When the cation exchange sites bond with Ca and Mg rather than Na and K, it is “buffered”. The bonds that hold the Ca and Mg to the sites are very strong and cation exchange will largely stop. This means that all of the nutrients that you add to the water will be available to the plant at the ratios that you provide them.
