Anyone tried NPK Raw Silica powder

Just looked at my bottle of Shogun Silica and it contains 1.4 silicon dioxide and puts the PH through the roof. Am I missing something or is this to good to be true.

RAW Silica contains 45% silicon dioxide which is the highest concentration of silicon dioxide available to the home gardener. RAW Silica is flowable and suspendible in water and naturally available to the plant. Since RAW Silica is a natural form of silicon dioxide, it is pH neutral and does not cloud when added to water. RAW Silica can be used during all stages of growth and bloom for optimal stem and cell wall strength. It is a beneficial supplement to all feeding schedules. A 2 oz package of RAW Silica makes up to 200 gallons, an 8 oz package makes up to 800 gallons, and a 2 lb package makes up to 3200 gallons.

It’s good stuff. I use it

I'm trying it out. I think it's a bit expensive for what it is.

Unless your growing soil less/hydro..

It really won't do anything for a soil grow!
The plant will get ALL it can use from the soil naturally.

As far as it not clouding the water.. it sure as hell will, if you mix it improperly - with Ca. Any form of Calcium too!
It forms a precipitate and locks each other out.

Ca first and Si last, or vise versa.... Mix well with water added with each thing you add. STIR constantly while adding the last thing - Si or Ca!

Using Silicons is probably one of the best ways to control the plants from stretching. There's a lot benefits to using Si in hydro or DTW
I havent checked out RAWS Si but after looking at the label, I see it claims 45% but after nutrients are added and the solution is ph'd the bioavailability is going to be significantly less. I think its something like < .05%

Right now, I'm using monosilicic acid (H4SiO4) in an amended coco/peat based media and liking the results. I use .5ml/gal and shot for target ppm of >28

You might like Agisil16. The reports on it are very positive. And remember, most of the powdered forms available are just finely powdered diatomaceous earth which needs a good microherd to become bioavailable.

Necro thread got me, lol.

so says RAW

Silicon Dioxide ='s Silicon Dioxide at days end. I think I will try out a Silicon Dioxide product from the ceramic industry. They use it to make glazes.

It's 23 cents an ounce versus the $5 an ounce I just gave Amazon for the RAW.

Ceramic supply may be a bit more coarse, I'm not sure, I can get a 320 mesh readily. Not sure how that compares with the RAW fineness.

Thoughts?

Sigh

This is getting out of control! The use of powdered SiO2 is NOT a good idea for YOU or your plant.... SiO2 is not in a form readily available to the plant. The idea that they would sell you straight SiO2 is kinda cheating....It is powdered crystal...
NOT TO MENTION THE POWDER, IF INHALED.. CAN GIVE YOU WHAT IS CALLED SILICOSIS!

FROM WIKI; Inhaling finely divided crystalline silica is toxic and can lead to severe inflammation of the lung tissue, silicosis, bronchitis, lung cancer, and systemic autoimmune diseases, such as lupus and rheumatoid arthritis.
The above links are active....

To use SiO2 for plants. It should be spread on soil so it can be broken down as much as possible by the activity in the soil.
In hydro - SiO2 is not broken down in water the way it would need to be to be available by the plant in the time frame of growing as effectively as you would like!

Now what is mostly used for agricultural Si is Potassium Silicate. This still contains the don't breath it Si but, it is actually 8.3 or 8.4% soluble Si - When you use Agsil-16H - This is highly recommended by Build a soil.... On grains we use a liquid form by the same company.

There is also Agisil 21 and 25. These are differing concentrations, for differing applications....These 2 are in liquid form. 16H is powder..

You must keep in mind that 16H is very high in K....
All of these forms are far more plant available then straight SiO2!


Basic info from Certis.....
I suggest you all dig deeper and avoid SiO2 in powdered form!

Are you saying that the Silicon Dioxide that RAW is using is really Potassium Silicate ???

You're saying that RAW is killing folks with their powdered silica product???

You're saying that RAW Silica should only be applied to the soil surface?

BTW, the don't breathe the dust, applies to EVERYTHING!.

NO it's not and that's the bad part - IT SHOULD BE!

"Buyer beware" - It's up to YOU to know that's it's bad Ju ju

NO, mix it into the soil BUT, Silicon Dioxide is not effective enough to really be used OVER Potassium Silicate!

Thanks for clarifying. Checking it out now via the web and appears there are arguments for either product, sifting my way thru that for facts. Meanwhile I'll be mixing my 200 gallons up based on this 2 oz pack and see if I see any differences or anything at all.
