Thanks again guys for all the great info!
Unfortunately, price is a bit of an issue so I'm gonna stick with the Azomite for now. Next go round I'll definitely be getting some gaia green.
As for Bentonite, I did some reading on it and found that some kitty litters are made from exclusively calcium bentonite...anyone have any experience with that? Suggest any brands?
I've been calling around to local shops all day looking for oyster shells or crab meal...no luck yet. As for basalt, I found a company called Cascade Minerals that looks to have a real good basalt powder and I found one store that can ship to me..I may wait on it til my next batch but at least I have a source.
Also, I found an add on craigslist today for a local gardener who was advertising high grade worm casting, compost and humate. I called him up and we chatted for a while, he really knows his stuff...even invited me to come check out his gardens to see the results. I told him a little bit about what I'm going for and he assured me that his stuff is so good, I wouldn't need any amendments, just mix the compost with a good base soil and add his EWC and I'd be set. Not sure if I buy that, but I'm definitely interested in what hes got so hopefully next week I can get over to his ranch and check it out. He's selling a cu/ft of compost for $8 and a gallon of EWC for $15...seems a bit steep on the EWC but he assured me it's way better than the stuff in stores.
Really excited to start mixing soil this weekend provided I can find a good calcium carbonate....hopefully start colonizing some IMO too.
