Re: Clay Substrate How-To
Ed, if you did decide that a top dressing was in order after a few years, would you put a small batch of new, complete clay mix over the top, or do you think that you could mix some Calcium Bentonite with a little Calcium Carbonate, both in their dry form. Sprinkle that over the top of your moist clay, and perhaps cut off the misting for a couple days to allow time for the Bentonite and calc. carb. to adhere to your old clay? I guess I'm thinking maybe 90 percent calcium bentonite and 10 percent calcium carbonite.
Questions are not ignorance. Questions are the birth of knowledge.
