Buffer question
    #4280566 - 06/10/05 05:30 PM (12 years, 4 months ago)

I'm going to use the horse  :poop: tek and I was wondering what I Should use for a buffer and how much... and what exactly dose a buffer do?

Peace :peace:

A buffer is for a casing layer, not horse poo. Some bulk substrate mixtures might require PH adjustment, but horse poo certainly does not.

To find a place to live between the negatives and positives.

From one smurf to another lol...A buffer alters the pH. Its not needed in the poo, but you should add some powdered osyter shell (aka powdered limstone, aka calcium carbonate) (5%) to your peat moss (or coco coir) before adding the perlite when your making your casing mix. Hydrated lime can also be used with peat moss (not coco coir, not needed) to get the pH to 7 to start.

Mycelium like a pH of 7. Hydrated lime is soluable in water (that word hydrated..) but limestone is not. Limestone however will break down slowly, overtime when exposed to acids. Mycelium secretes acidic wastes as its life cycle goes on...so you get the pH to 7-7.5 to start (coir come at 7, peats like 4-6ish) using hydrated lime, then add calc carbonate (powdered oyster shells is the cheapest form IME) which will break down over time to keep the pH neutral.

"life is like a drop of rain getting closer and closer to falling into a lake, and then when you hit the lake there is no more rain drop, only the lake."

Growing with bags, start to finish (including my new grain and substrate prep)
