Yo, my next mix I'm going with
Thirds of cspm, ewc and pumice
1c each kelp & neem
4c basalt & 5c bio char.
My ewc still has 6 to 8 months left before I'll use it.
It's basically just homemade compost, a bag of Malibu compost, bio char, kelp, neem, basalt, gypsum, crustacean meal, pumice and rice hulls... and worms and other bugs
I threw some amendments in I had sitting around from previous mixes that I don't use. Now that I think about I can lower my amendments and pumice in the mix I'll be using since the ewc has them.
I'm gonna pop some of bluejays work and do 12/12 from start till they sex and then switch to veg. he said he hasn't had an issue with it.
I still have my original coot mix soil, it's going on three or four years, I forget what year it was but I made it about a month after LOS.org started. I don't know if you remember but I was gonna get soil from Jeremy and you said nah you gonna make it, that's what this is about! I have 6 or 7 cycles in it now!
Here's my ewc. The bottom of the tub is cut then I put a bunch emt pipe going across with cardboard on top of the emt.
