In the mix: Wollastonite, Greensand, Gypsum.

Those three are going into a mix of 1/3 humus/topsoil, 1/3 ProMix Vegetable & Herb mix, 1/3 native clay loam. How much of the three additives would you mix into each 1 cubic foot hole?
Thank you.

Add a bag or perlite get you some 444 all purpose , ewc or compost and u have the start of some decent soil.
the 3 additives aren't going to provide balanced nuitrients, greensand takes years to breakdown I've read

Definitely will need more aeration than the perlite in the pro mix and .33 clay isn't going to work lots of time left to do some reading

a cup of each. add you some perlite to lighten up dat clay shizzle, yo!

Thanks.

The humus/topsoil contains a fair bit of leaf compost [from commercial supplier] and the ProMix is mostly peat with some Perlite. If it looks to need thinning out once it's in the hole, I will thin it.

Maybe go a bit heavier on the gypsum to help break up the clay.

And if this is going to be long term no till I would use course sand or fine gravel rather than perlite for aeration. Perlite breaks down over time.

I would add some vermeculite also. It has a higher CEC.

I agree with that but I have to backpack it in. Still, I'll consider it. I like sand in a mix, but it's heavy to carry.

Yes, I like vermiculite, although some folks on this site swear against it.

Yup, that kind of takes sand out of the picture if you have to haul it in.
With the few years you will be using it at the max with a guerilla grow perlite will work just fine.

Perlite is glass that has been heated like popcorn. Is it a source of silica? I need to start incorporating pumice into my mix, and something so I don't have to keep adding cal-mag to the water.

So speaking if "ites", some of this showed up today. It's not very soluable in 6,8 pH water, so I sprinkled a TBSP on top.



Here is another "ite" that I have been sprinkling on top:

I need to get some fulvic also.

Langbeinite is a good tool but use it sparingly. Can lock out calcium on you.
Best time for some is just as they turn to flower.

I like sand in a mix, very much, so I will use as much as I can work in there.
