Cyco Platinum Series Silica (0-0-3)

Cyco Silica Is 3% Potash And 3% Silicon

The silicon here is not legally a plant food. On a fertilizer label silicon is declared separately, under non-plant food ingredients. That is why Cyco Silica reads as 0-0-3 with 3% soluble potash, then lists 3% silicon underneath it. Both come from the same source, potassium silicate. That is the entire formulation. The potash is what the guaranteed analysis measures. The silicon is what most growers came for.

Cyco Platinum Series Silica Runs At 1 To 2 mL Per Litre

Add it to the nutrient tank at 1 to 2 millilitres per litre. Then test pH and TDS and bring both back to your usual levels. That instruction is on the label for a reason. Potassium silicate is alkaline and it will move both readings when it goes in. There is no separate veg or bloom rate and no published foliar rate, so one number covers the whole cycle. One honest note on where this sits. At 3% silicon it is among the stronger liquid silicates on this shelf. It is still a straight silicate like most of them, so expect the same pH correction every time you mix.

Key Features

• 3% silicon from potassium silicate: Declared on the label as a non-plant food ingredient, which is how silicon is legally listed on a fertilizer.
• 3% soluble potash: The 0-0-3 on the front of the bottle, and the only figure the guaranteed analysis actually measures.
• 1 to 2 mL per litre, one rate: No veg and bloom split and no weekly ramp, so nothing changes when the room flips.
• Single named source: Potassium silicate for both the potash and the silicon, which makes it predictable against a known base feed.
• Part of the Cyco Platinum Series: It sits on Cyco's own feed chart rather than being an orphan bottle bolted onto a schedule.
• Label tells you to re-test pH and TDS: An alkaline silicate moves both, and the manufacturer says so plainly instead of leaving you to find out.
