It delivers a water-soluble form of silica that rapidly strengthens plant cell walls, improving resistance to heat, drought, and other stressors. Compatible with all nutrient systems and crafted in the USA by expert botanists, this premium formula supports larger, healthier plants while offering exceptional value for conscientious growers. ## Description Bloom City’s Silica Boost formulation delivers water-soluble silica directly to the plant’s roots. Improves heat and drought tolerance, increases plant resistance to environmental stressors, and improves water uptake in the root zone. Silica Boost builds strong plant cells and increases growth. Add Silica Boost to every watering to keep plants healthy.Other Silica brands use un-available forms of silica, which will sit locked-up in your root-zone for weeks before roots can uptake the minerals. Slow uptake times mean much less effective results. Bloom City’s proprietary 100% organic acid complexed Silica Boost increases bioactivation, which means much faster uptake times and stronger plants.Bloom City nutrient systems are an ultra-premium line designed for the craft grower. Our nutrients and supplements are simple to use and produce amazing results. Leave behind the confusing and dirty world of Big-Ag fertilizers and upgrade to Bloom City. Bloom City’s products are made in America from the highest quality sources by a small team of passionate plant scientists. All our ingredients are better for plants, better for you, and better for the planet. Bloom City is simply the best choice for the conscientious grower.

Common sense not so common. Of course it’s an absolutely brutal sticker to remove as well.

Can I add other nutrients to the same water with silica? Thank you!** A: You can add other nutrients, but they should be added in a particular order, with silica being added first. It’s important to add each nutrient in the proper order and mix thoroughly before adding the next. Silica is always the first to be added. ## Customer Reviews ### ⭐⭐⭐⭐ Review *by T***A on 19 January 2026* The dumbest thing about this purchase was the fact that the bottle has plenty of open space with no writing, but they put their barcode sticker DIRECTLY over the instructions.
