Potassium silicate water conditioner — stabilize RO water and set pH before you mix a drop of nutrient.
Athena Blended Balance (0-0-2) is a concentrated potassium silicate formula built to buffer reverse osmosis irrigation water to a stable pH before fertilizers are introduced — eliminating the inconsistent baseline that causes drift, lockout, and erratic feed chemistry. Beyond pH control, the silicate component delivers measurable secondary benefits: stronger cell walls, improved stem structure, better osmoregulation, and more efficient nutrient utilization across the crop cycle.
Athena Blended Balance is a liquid potassium silicate concentrate formulated specifically to buffer irrigation water and bring it to a stable, plant-ready pH — with particular effectiveness when the source water is reverse osmosis. The guaranteed analysis is 0-0-2: 2% soluble potash (K₂O) derived from potassium silicate, plus a 5% silicon dioxide (SiO₂) beneficial substance listing. It is part of Athena's Blended Line, a liquid two-part nutrient system built around repeatability and clean chemistry.
The formula is clear, sediment-free liquid — compatible with mechanical dosing systems including Dosatron. Athena explicitly does not recommend it for electronic dosing systems such as Netafim venturi-style injectors; operators running those systems should look to Athena Pro Balance (potassium carbonate) instead. The 55-gallon drum (SKU: LQB-SIL-55G) is the commercial-volume format, sized for operations that go through meaningful quantities of buffer product weekly.
Pure RO water presents a specific mixing problem: its near-zero alkalinity and unstable chemical structure can trap or precipitate other nutrient inputs when they are added to an unbuffered tank. The practical result is an inconsistent solution — the nutrient mix your plants receive changes from irrigation to irrigation even when you dial the same feed chart. Athena Balance is added to the reservoir first, before any base nutrients or additives, to stabilize that chemical structure and create a homogenous solution. This step reduces the need to chase pH after mixing and cuts the frequency of post-mix pH corrections.
The approach also delivers silicon directly into the crop program without a dedicated standalone Si product. Silicon — present here as 5% SiO₂ — reinforces plant cell walls, contributes to improved stem structure, supports stress tolerance (heat, drought, pathogen pressure), assists with osmoregulation, and improves overall nutrient utilization efficiency. For licensed cannabis operators running RO-sourced irrigation, this is a foundational input, not an optional additive.
The Athena Blended Line is organized around a two-part base nutrient per growth stage — Grow A+B through vegetative, Bloom A+B through flower — with a consistent roster of supporting inputs that carry through the full 13-week program. Balance is the first product added in mixing order at every irrigation, from propagation through finish. It is used alongside Grow A+B, Bloom A+B, CaMg (for additional calcium and magnesium in RO/inert-media programs), PK (a mid-to-late flower booster), and Cleanse (a system-maintenance hypochlorous acid product).
Operators who are already running Athena Pro Line dry concentrates and want liquid convenience for their water-conditioning step can run Blended Balance in the same program — it integrates cleanly. Athena publishes both metric and imperial feed schedules that include Balance dosing targets week by week. The 55-gallon drum format at this SKU supports high-frequency, high-volume commercial operations that need to standardize inputs across multiple zones or cultivation rooms.
Athena Blended Balance is compatible with rockwool, coco coir, peat/soilless blends, DWC/recirculating hydroponics, and run-to-waste drip systems. It is cleared for use through Dosatron and other mechanical proportional dosers. It is not recommended for venturi-based electronic dosing systems (Netafim-style) — the potassium silicate formulation can interact with these setups; Athena's Pro Balance (potassium carbonate) is the appropriate product for those configurations.
Application rate is approximately 2–5 mL per gallon of irrigation water, added to the reservoir first before any other inputs. Always add Balance to water — not the reverse — and allow thorough mixing before introducing base nutrients. Monitor pH after mixing and calibrate pH instrumentation before measuring; the formula can cause a minor thermal reaction in the mixing vessel, so allow the solution to stabilize before taking readings. Store the drum closed in a temperature range of 45°F–85°F. The 55-gallon drum requires LTL freight — standard pallet delivery applies.

Pure RO water has an unstable chemical structure that can trap or precipitate nutrients when they are introduced into an unbuffered tank. Adding Balance first stabilizes the water chemistry and creates a more homogenous solution — so every gallon of irrigation water carries the same nutrient profile. It also raises pH toward the target range before fertilizers go in, reducing the need for post-mix pH correction.
No. Athena explicitly does not recommend Blended Balance for venturi-style electronic dosing systems such as Netafim. Potassium silicate can cause issues in those configurations. For electronic venturi systems, Athena's Pro Balance (potassium carbonate, 100% soluble) is the compatible product.
Balance covers your silicon input. The guaranteed analysis lists 5% Silicon Dioxide (SiO₂) as a beneficial substance, derived from potassium silicate. Athena's own documentation notes that no additional potassium silicate products are needed when Blended Balance is in the program.
It works across cultivation methods — recirculating DWC, coco coir run-to-waste, rockwool, peat/soilless, and soil. The primary use case is with RO water source, regardless of media type.
For commercial operations running RO source water across multiple zones or rooms, Balance is used at every irrigation throughout the full crop cycle. The 55-gallon drum lowers per-gallon input cost and reduces the frequency of reorders. It ships LTL freight on a pallet — HSC can coordinate delivery to your facility.
