Pro-Silicate is a nutritional silicate additive containing potassium and silicon. It helps keep the plants upright, positioning the leaves correctly for maximum light exposure that ultimately leads to more food production because of a high rate of photosynthesis. Pro-Silicate helps the plant battle wilting and drought by acting as insulation against excess water loss at higher temperatures. This helps increase plant growth and prolongs bloom life.

This product actually does do what it claims.
The branches of my tomato plant noticeably stronger, especially useful when it is applied just as the fruits begin to form and the plant sends signals to build up the load bearing arm from flowers to fruit. When I made the liquid silicone available to the plant as it was thickening the fruiting arm, it was noticeably stronger, more flexible. To the point where my maters were swaying in a strong breeze and the plant held firm.

As an added bonus, when I need to use Neem oil foliar spray to get rid of the white flies on my pepper plants (and add potassium and silicon) the silicon emulsifier present in the product that allows it to mix well with water also bridges the water-oil gap.

Thickened my stalks up good
Careful though it’s extremely basic you will need to add acid to fix your water

Used in an attempt to remedy issue. It hasn’t harmed anything, but can’t conclusively say it helped either

This is a very good silica product. Silica, used in the proper amounts, helps prevent nutrient lock-up.
