MonoSil Stabilized Monosilicic Acid (OSA) - 1 Gal - Liquid Concentrate

Plant-Available Silicon for Sturdier Growth - 1 Gal Liquid Concentrate

Many growers want stronger stems and better stress tolerance but find that some silicon sources are hard to dissolve or disturb solution pH. MonoSil supplies silicon as stabilized monosilicic acid (orthosilicic acid, H4SiO4), a form plants can take up. It is a liquid concentrate that mixes into feed water or goes on as a spray or drench.

The 1 Gal unit suits regular indoor growers and small to mid-size operations that want a steady silicon supplement through vegetative growth and flowering without buying in bulk. Small gardens will get many feedings from one container.

Key Features & Benefits

• Stabilized monosilicic acid — supplies silicon in a plant-available form.
• Liquid concentrate — measures and mixes easily into nutrient solution.
• Four application methods — fertigation, foliar, soil drench or top watering to fit your setup.
• Works across systems — suited to hydroponic, soilless and soil-based cultivation.
• Defined pH window — a recommended nutrient solution pH of 5.8 - 6.5 makes it simple to plan around.

Who Should Use Pro Liquids MonoSil

Growers running hydroponic, soilless or soil-based systems who want to add silicon to their feeding program. Fertigation suits automated systems, while foliar and drench methods suit hand-watered gardens.

About Pro Liquids MonoSil

MonoSil is a stabilized monosilicic acid solution, derived from monosilicic (orthosilicic) acid, sold as a liquid concentrate. The label lists a monosilicic acid (H4SiO4) content of 2.7%. Use it as directed on the label.

Frequently Asked Questions

Q: What is monosilicic acid?
A: Monosilicic acid, also called orthosilicic acid (H4SiO4), is a simple soluble form of silicon. MonoSil stabilizes it so it stays usable in a concentrate.

Q: How do I apply MonoSil?
A: You can apply it by fertigation, foliar spray, soil drench or top watering. Follow the label for rates and timing.

Q: What pH should my nutrient solution be?
A: The recommended nutrient solution pH is 5.8 - 6.5. Check and adjust pH after mixing.

Q: Can I use it in hydroponics and in soil?
A: Yes. It is suitable for hydroponic, soilless and soil-based cultivation systems when used as directed.

Q: How does it differ from other silicon sources?
A: Some silicon products are less soluble or less stable in solution. MonoSil supplies silicon as stabilized monosilicic acid, a dissolved form designed to be available to plants.
