Aqualine Pressure Sprayer - Fast, Even Coverage for Foliar Feeds and Sprays
Best for: Growers applying foliar feeds, pest treatments or disease control who want full coverage without hand-pumping a trigger bottle all day.
Our thoughts
If you've ever tried to spray a full tent with a cheap trigger bottle, you'll know why a pressure sprayer earns its keep - pump it up once and you get several minutes of continuous, hands-free spraying instead of finger cramp. It's a small purchase that saves real time on spray day. One we sell a lot of for new growers who are just getting into foliar feeding or pest control.
The Aqualine Pressure Sprayer is a hand-pumped pressure tank sprayer: you fill the tank, pump the built-in plunger to build pressure, then squeeze the trigger to release a continuous, adjustable spray. It's built for growers who want full coverage fast, with a trigger lock for hands-free spraying over longer sessions and minimal hassle setting it up.
It comes in 1, 3, 5 and 8 litre tank sizes, with the larger 5L and 8L versions fitted with a shoulder strap for carrying while you spray. The nozzle is adjustable from a fine mist through to a full jet, and the tank has a wide fill opening so mixing concentrate directly inside is straightforward. A pressure relief valve prevents the tank building up excess pressure, and the tank material is designed to resist most common garden and grow-room chemicals without corroding.
How it compares
Pressure sprayers like this sit above basic trigger bottles and below professional backpack sprayers in both price and capability.
- Hozelock, a well-known name in UK garden pressure sprayers, makes similar pump-action tank sprayers, but Aqualine's range is priced specifically for grow-room use rather than general garden retail.
- A basic trigger spray bottle is cheaper but means constant hand-pumping and inconsistent coverage over a full tent or multiple plants.
- Full backpack sprayers offer more capacity again, but are overkill for most home and small commercial grow spaces.
You get pump-once, spray-continuously coverage at a price that suits a home or small commercial grow room, without paying for capacity you won't use.
Usage guidance
A few basics make spraying sessions faster and more even.
Filling and mixing
Use the wide-mouth opening to mix your foliar feed or spray solution directly in the tank, then seal and pump the plunger until you feel resistance build.
Spraying
Adjust the nozzle to a fine mist for foliar feeding and a firmer jet for reaching deeper into foliage, and use the trigger lock to hold a continuous spray without gripping the trigger the whole time.
After use
Rinse the tank and nozzle out after each use, especially after spraying anything acidic or oil-based, to stop residue building up and clogging the nozzle next time.

Our take
A genuinely useful bit of kit that pays for itself the first time you use it on more than a couple of plants - continuous, adjustable spray beats a trigger bottle every time.
Does exactly what it should, day in, day out - pick the tank size that matches your grow and get spraying.
