Silicic Acids For Hydroponic Plants

While silica isn’t categorized as an essential plant nutrient, it still remains an important nutrient in the plant growing room and has application through various stages of growth. For this reason; you can aptly refer to it as the jack of all trades in the plant nutrients kingdom. 

mono silicic acidWhat is silica?  Silica is simply a common term for the compound silicon dioxide (SiO2). It is naturally occurring and abundant in many soils and a key component of plant tissue, even in higher concentration than other macronutrients such as nitrogen and potassium. It is usually made available in the form of mono silicic acid and orthopaedic silicic acid, by the micro-organisms in the soil. Because it is not categorized under the essential nutrients for plants generally, most growers have come to believe it is not essential in a normal feeding regimen. In reality, the benefits of silicic acids are nearly endless, the four most important functions being –

  1. Stronger cell walls, leading to bigger stems
  2. Increased resistance to pathogens and environmental stress
  3. Enhanced metabolic function
  4. Increased resistance to pests

Tips For Picking Silicic Acid compounds

Now, picking a brand of the nutrient may be quite challenging with so many to choose from, but here is, however, a tip to aid the process- When picking a brand of silica, ensure you choose only one with a high concentration of silicon dioxide so it works more effeciently.

Stout MSA

In hydroponic cannabis cultivation, the importance of silicon cannot be emphasized enough. While there are several options and additional supplements available in the market for cultivating cannabis hydroponically,  not so much is required to cultivate healthy cannabis, but even at that, it is wise to consider the use of silicic acid and one product we highly recommend is the Stout MSA from Alchemist. There are several potential benefits it can offer to growers. 

MSA promotes faster growth and helps improve cell development by accelerating the production of plant cell walls. When cannabis plants have access to all they need, the development process of the plant goes at its highest possible speed. It results in strong stem and stalks that can support larger buds or fruits. And the end result? Faster yields and more harvest!

Silicic has been found to reduce plant stress from heat, frost, and drought damage and the MSA does just that. What is more? The user-friendly application rate of 5mL per gallon makes it simple to use with dosers and injectors. 

Elite 91 Silicic Acid

Utilizing innovative new methods, Elite 91 Silicic Acid pushes the boundaries of the chemistry of silicon and its forms to the limit. Even though the product is completely soluble, it is still highly concentrated. 

Each bottle is enriched with 1.2% bioavailable silicon, and 4.1% Monosilicic acids concentration. It also includes zinc, molybdenum, boron etc. and supplies multiple essential micronutrients.In addition, it also has 21 L-amino acids that further support plant growth and health.

Elite 91 SILICIC ACID has been proven to supply bioavailable monosilicic acids down to the roots of the plants, enabling them to absorb the needed nutrients more effectively and grow to their fullest potential and yield the best buds.

Power Si Silicic Acid

Power Si, an original patented form of stabilized, bioavailable silicic acids for crops, it doesn’t just strengthen the plant, it transports immobile nutrients throughout the plant and makes them much more available.

Just as available when used on other plants, Power Si substantially reduces salt build-up and dehydration in hydroponically-grown cannabis and also the space between the internodes caused by environmental stress and nutritional imbalances for better crop health.  Moreover, it doesn’t change the pH in the tank and is easy to use with other nutrients.

In essence, silicic acids can be helpful in several cases, and if you’ve never used it on your plants before, we strongly recommend that you try at least one on our list, and see the difference. Yes, they can still be used even in cases where there isn’t any obvious stress or pathology. Including some quantity of silicic acids from the early stages of growth will significantly improve plant’s health and ultimately increase plant yield. To understand dosing and mixing, visit
