FAQ
A hose-end fertiliser sprayer applicator works by automatically mixing fertiliser with water as you spray. Fill the 1L bottle with fertiliser and water according to the recommended mix, set the sprayer to Setting A, select your desired dilution ratio on the dial (1:10 to 1:128), connect it to your garden hose, and apply evenly across the area. After use, flush the sprayer with clean water to prevent residue build-up.
This sprayer is designed specifically for applying CompleteGrow liquid fertilisers and soluble powder fertilisers. It is suitable for products such as NPK 20-20-20 liquid, NPK 20-20-20 soluble powder, Advanced Formula 4-18-38, and citrus fertilisers. Using compatible fertilisers ensures accurate dilution, consistent feeding, and reliable EC results.
Yes. The EC values listed for this sprayer are based on real-world use with Setting A and the recommended fertiliser mixes. Because hose pressure and water quality can vary, EC readings may differ slightly between locations. For best accuracy, always use the same sprayer setting, follow the mixing guide, and adjust feeding strength gradually based on plant response.
The correct dilution ratio depends on the feeding strength you want. Lower ratios (such as 1:10 or 1:20) deliver a stronger feed and are best for heavy feeding during flowering or fruiting. Higher ratios (such as 1:64 or 1:128) provide lighter feeding for maintenance or sensitive plants. All mixing and EC guides provided for this sprayer are based on using Setting A.
