FAQ: How to make the most of your hose end sprayer.
What is a liquid fertilizer hose end sprayer, and how does this one work?
A hose-end sprayer like this one attaches directly to your garden hose, mixing liquid fertilizer or other concentrate as you spray. Ours is pre-calibrated with a 100:1 dilution ratio, making it perfect for feeding lawns, treating weeds, or applying pest control with zero pre-mixing.
Is this just a hose sprayer bottle that attaches to a garden hose, or something more?
It's a professional-grade tool designed specifically for concentrated solutions. With its K1 spray head and mode selector dial, it offers consistent flow and wide coverage — far more efficient than basic hose sprayers or repurposed bottles.
What types of products can I use with this sprayer?
It's ideal for use with liquid fertilizers, herbicides, insecticides, plant soaps, and outdoor cleaners. Works seamlessly with Humboldts Secret products and other water-soluble solutions.
Will this work with my hose at home?
Yes. It fits any standard 5/8" garden hose with no special adapters required.
Is this hose sprayer bottle safe for edible plants?
Absolutely. Just rinse thoroughly between uses and keep one sprayer dedicated to food-safe applications like fertilizers or organic pest control.
How do I clean and store the sprayer between uses?
After use, empty any remaining product, rinse the bottle and sprayer head thoroughly with clean water, and let dry. Store in a cool, dry place.
How does this compare to other fertilizer hose end sprayers?
Unlike many lower-quality options, ours delivers consistent, controlled mixing with a proven 100:1 ratio. It’s designed to be reusable, leak-resistant, and highly compatible with concentrated products, especially those from Humboldts Secret.
Can I use more than one sprayer at a time?
Yes, and that’s what many growers prefer. Use one bottle for fertilizer, the other for pest control or soap. Label them for faster swaps between jobs. It’s the easiest way to streamline your weekend watering routine.
Wield it for real results.
Feed, treat, and clean with speed and confidence. Our sprayer offers precision and control in your hands — for thriving gardens and unstoppable workflows.
