Agsil 16 H (Potassium Silicate)

0-0-32

Agsil 16 H is a soluble form of Potassium Silicate that will provide your plants with a 100% available source of silicon and potassium essential for optimum plant growth and health. Potassium Silicate will strengthen your plants internal processes during periods of excessive stress and external defenses against foliar and soil diseases. Benefits include stronger cell walls, increased stem strength, increased heat, drought and cold tolerances and longer lasting leaves and blooms!

Agsil 16H is a simple and inexpensive alternative to water-based Silica products – now you can make your own for pennies on the gallon.  560 grams of Agsil in 1 gallon will give you 7.6% silicon (SiO2).

Derived from: Potassium Silicate

Guaranteed Analysis
Soluble Potash (K20): 32%
Silicon Dioxide (SiO2): 52%

SUGGESTED APPLICATIONS

Use ½ teaspoon per gallon of water as foliar spray, soil drench or emulsifier

Recipe for 7.8% Solution:

780: 1
148g : 1 L
560g : 1 gal

Mix 148 grams AgSil 16H into 1 liter water or 560 grams per gallon.  Store in bottle or jar and shake well before use. (1 lb = 454 g). Use this 7.8% solution at 1/4 - 1/2 teaspoon per gallon water.

WARNING: Causes eye and skin irritation. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling.

Never mix concentrated silica solutions with other concentrated fertilizers.  It is best practice to make up the liquid solution first or add water prior to mixing the powder with other ingredients or nutrients.

When mixing, be sure to add water to the container first. Fill the container halfway with water and then add the Agsil before filling the rest of the way and then mixing thoroughly. 

STORAGE

The silica needs to be stored in a cool dry location. There is no real shelf life to speak of if kept dry or in liquid concentrate form. We suggest you make the liquid concentrate for storage because if the powder gets any moisture it can turn into a rock. Shake vigorously before using.

Good all around

I can't comment on the effectiveness of the potassium silicate. We're still in the middle of winter. It'll be several months before I apply the product. Everything with ragards to the purchase, however, was good. I appreciate the home gardener size packaging. It will last me a few years. The posted instructions on how to mix a concentrate and then dilute to the proper ratio was most welcome. Thank you. Also, thanks for the excellent science based podcast. What a great find after sifting through all the stoner focused information that's available.

Excellent product and customer service!

I reached out, about adding to my grow and Tad was very helpful. He explained what I would need and what I don’t need. He also explained how to use the product. I just recently added it to my water and so far the plants are looking happy and healthy. It’s incredibly easy to use. Thanks again I’ll be back for more when I’m through with this.
