This. Wollastonite for the win. I mix it in soil before I plant. Donāt have to mix other stuff or use woo juice. Credit Bugbee.
Very interesting stuff. Please, no offense intended, but āmix in soilā is a little vague. Your soil is? No applications of anything drop to chop?
Now Iām off with reading in mind.

Use Vermiculite for natural silica.
It consists mostly of silica. Vermiculite comes from 19 varieties of micaceous minerals and the ores contain silica, alumina, iron oxides and magnesium oxide.
Although sand, pumice, perlite, vermiculite, rockwool are technically silicon materials, silicon from these materials is barely available to plants. In fact, silicon content in the plants growing in these soilless media is remarkably lower compared to the same plant species growing in natural soil.
Natural soil and Rabbit manure and a little duck manure for the win for me.
Iāve noticed in the long run regular soil grows plants best inside or out.
I teaspoon of regular soil has more microorganisms than all the people on earth.
Silicon is the second most abundant element in the Earthās crust, so not surprisingly plants growing in natural soils have evolved to absorb and use silicon to their benefit.

Iām with you and will stick with poo.
Seems to me itās just more nutrient hype to get people to spend moneyā¦ Then again, I use soil to grow in.
In nature cannabis rises out of the corpses of last yearās crop. Perhaps mulching with chopped up cannabis stems would be a good move, provided healthy plants make the mulch?

@shag I used Protekt for a few years. Iāve been using Armor Si now for a bit and donāt care for it. Iāve taken to mixing 5 gals at a time the day before I use it. Back to Protekt when Armor S I is gone.

Doc Bugbee indicated that vermiculite doesnāt do what we thought it did:

When I get ready to load grow bags I add only a couple things. First and foremost is about 2 solo cups of solution grade gypsum per cubic foot and wollastonite for slow release silica. I have to check my notes for how much but itās not a lot and last grow I could tell it helped with plant strength and had less flopping branches.

What mix are you putting those adds into? Thatās what Iām not seeing. Coco, peat, a zillion different āsuper soilsā. Lots of choices.

So youāre adding to a pre-made soil with slow release N. Crab and lobster meal. Kelp. Thatās not exactly ājust adding gypsum and wollasoniteā and just watering.
Kind of like saying I only use water on my outdoor plants, forgetting itās a repurposed organuc soil. āOnly water and teasā.
@Jasper not trying to argue at all. I like the possible use of the W-powder over Si in a jug. Iām pretty new growing indoors. Less than 3 years, so am learning a lot. Regional terminology has been an issue with all you Okies!
Ha! Lets see who corrects that really quick.

Yeah heās probably right. Iām definitely leary of using vermiculite but Iāve got some mixed with Ez blend Hydrafiber, meal worm frass, Bokashi Bran, that manure mix and old potting soil.
Bokashi bran can fix problems in container soils. Iāve topped dressed with it and had great results.
Iāll be making regular soil containers soon. I did some testing and found out peat has a carbon effect that equals all the cars carbon in America a year.
So Iām just using the old leftover junk for winter indoors till it wonāt grow again. Iāve had 10 harvest with the same soil. So it was time to compost the whole pile.

Thank you all for your contribution to this thread. 
For all you folks using SI in the soilā¦and I do like the different ways you folks mentioned to add SI to the soil.
Most of the stuff used in soil is not really in a sprayable form.
Do you ever use SI as a foliar spray to form a protective barrier against pests?
This is my favorite way to use SI myself.

So would this work Amazon.com : Horsetail Herb - 100% Natural - 1 lb (16oz) - Herbal Tea - EarthWise Aromatics : Grocery & Gourmet Food or an alcohol sugar free extract? Thanks for this info

It should, I donāt see why it would not.
You could use the herb as is or extract the silicon from the herb and use that depending on you goals.
I am not much help with the extraction of silicon from horsetail, I have never done it.
Wonderful thread! Thanks @shag for posting all the information and others for supplementary content.
Looks like Iām buying some AgSil 16H and making some silica juice.

Cool stuff in here. Thanks for sharing! Where do people get their wollastonite from? I wouldnāt mind tossing some in my soil.
