From BAS:
AGSIL16H is manufactured by PQ corporation and is one of the few silica products on the market that is water soluble. This simple powder will save money over buying water based Silica Bottle products. This is approved for organic use as a foliar spray and is an excellent oil emulsifier.
See the MSDS report here: AGSIL16H MSDS PDF
Compare to Pro-Tekt, Rhino Skin, Silica Blast and all other Silica Bottled products. There is no secret ingredient, all are made from potassium silicate.
Dry Recipe
Use 1.5 Grams (Just under 1/2 teaspoon) Per Gallon of Water for Foliar Spray or Soil Drench.
How to use this powder dry with your Neem Oil: Mix 1.5 grams (Just under 1/2 Teaspoon) AgSil 16H with 1/2 Ounce Ahimsa Pure Neem Oil to emulsify the oil. Then mix this emulsified oil with one gallon final volume spray solution. Spray every other week covering all plant surfaces (top and bottom of leaves) until it runs off.
Liquid Recipe
Make your own nutrient bottle! Here is a recipe to make a liquid version of a Silica Nutrient.
Just follow the mixing recipe below.
If you don't have a scale: Use 3 Tablespoons of Agsil16H for every 8 ounces water.
Following the above recipe to make 1 Liter of Liquid Solution you would mix 148 Grams of Agsil16H into 1 Liter of water. Then you can store it in a bottle or jar and shake well before using. (1 Liter of water is about 34 Ounces)
Here is a photo what 148 Grams of Agsil16H looks like. I weighed this out and then put into this container so you can hopefully do this without a scale at your house.
Use the Liquid Solution you just made at 1/4 to 1/2 teaspoon per gallon. Yes, it's safe to use on every single watering, but we don't do that because we don't feel it's required with ANY ingredient. Some people use Aloe and Silica with every watering and we have seen stunning results.
Use 1/2 teaspoon of the solution per gallon to foliar spray.
(I've used 2-3 Teaspoons per gallon without ill effects, but encourage you to start slow and see what you think)
