## Overview

Bloom City Liquid Silica Boost is a premium, water-soluble silica supplement designed to strengthen plant cell walls, enhance resistance to environmental stressors like heat and drought, and increase overall plant size and weight. Compatible with all nutrient systems and made in the USA with organic, high-quality ingredients, this concentrated 8 oz formula yields 45 gallons of potent plant booster, ideal for both indoor and outdoor gardens.

## 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. For both indoor and outdoor plants, and both soil and hydro gardens. 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.

Review: This is a new twist to me on plant fertilizers. It's very concentrated and will make about 45 or so gallons. That alone makes it economical to use. I've heard non-stop from some gardeners and hobby growers how fantastic this is and a must have for the best results. The silica promotes plant growth by strengthening stems and overall great sturdy appearance, because your plants now have the silica advantage. Not only does it make strong & sturdy stems, the thickness is noticeable to the eye, insects hate this stuff, so that is a huge plus. Pleased to know about this silica because I never would have even thought about it as a fertilizer, but with so many enthusiastic recommendations I knew I had to check it out, houseplants looking better than ever, waiting for a few more weeks for outdoor plants and veggies. 45 gallons will go very far, and judging by friend's results this is money well spent, anything to help my plants thrive for the time and effort is spent , so you might as well go for the maximum result! Happy Gardening! Recommended!
Review: Bought for my monsteras. I believe it has helped with my albos and kept the white from browning and dying. I will buy again when I need it. This bottle has lasted me at least 8mo this so far, so I’d say that’s great value for your money! Also, it saves your plants, makes them stronger, and it’s easy to use…so win win!

## Features

- PROTECTS PLANTS FROM EXTREME CONDITIONS: Silica Boost strengthens cell walls and helps keep plants growing even in tough conditions. Silica can help increase plant defenses from all sorts of stressors - heat, humidity, drought conditions, and more.
- INCREASES PLANT SIZE AND WEIGHT: Many plants are silica accumulators, which means the more silica they get the more silica they build into their cells. The result is healthier and larger plants. Apply Silica Boost during all stages of growth and bloom
- COMPATIBLE WITH ANY NUTRIENT SYSTEM: Contains a water-soluble form of silica that is 100% compatible with other nutrient systems. For best results add Silica Boost to feed water first, then other nutrients
- HIGHEST QUALITY, MOST POTENT, BEST VALUE, BIGGEST YIELD: Bloom City’s ingredients are better for plants, better for you, and better for the planet. Simply the best choice for the conscientious grower
- FORMULATED AND MADE IN THE USA: Designed by botanists and plant chemists in Seattle, Washington. Bloom City chooses only the highest quality ingredient sources and manufacturing methods to create the world’s best craft growing nutrient systems

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.

*by M***E on 1 June 2025*

Legit. I have seen the results! Plant stems are sturdier and also my plants that had been having aphid problems are now standing up a lot better against them. Leaves are healthy and have a level of shine and brilliance that I haven’t seen in my plants before. Going to be buying myself a second bottle! P.S. It does have a smell but it doesn’t bother me. To me it just smells like Miso soup, and I kind of dig it, actually.
