Grow1 Pump Sprayer – 4 Gallon

The Grow1 Pump Sprayer is a 4-gallon (16L) hand-pump compression sprayer built from high-grade polyethylene plastic that resists corrosion from insecticides, herbicides, and fertilizer concentrates. Rated at 29–59 PSI, it includes a heavy-duty 5ft hose, an on/off trigger with a convenient lock, a safety and pressure release valve, and a padded carrying strap for comfortable use in the garden or grow room.

Why Choose the Grow1 Pump Sprayer

For growers who need a reliable compression sprayer that can handle a range of liquid inputs without tank degradation, the Grow1 Pump Sprayer offers several practical advantages over entry-level garden sprayers:

• Corrosion-resistant polyethylene tank: The high-grade polyethylene construction does not react with common insecticides, herbicides, or fertilizer concentrates, so the tank stays functional over repeated use cycles with different chemistries.
• Trigger lock for continuous spraying: The on/off trigger includes a lock position that holds the valve open without requiring constant hand pressure, which reduces fatigue during longer spray sessions covering large canopies or multiple rows.
• Integrated safety and pressure release valve: The built-in pressure release valve allows you to safely depressurize the tank before opening the lid — an important safety feature when working with any pressurized liquid container.
• 5ft heavy-duty hose: The longer hose gives reach into tall canopies, under benches, or across wide trays without repositioning the tank, keeping application consistent.
• Carrying strap for portability: The included strap means you can carry the filled tank hands-free between spray passes, keeping one hand available for directing the wand and adjusting nozzle angle.

Best Uses for the Grow1 Pump Sprayer

The Grow1 Pump Sprayer is suited for any liquid application task where controlled, pressurized delivery matters. Its corrosion-resistant tank makes it appropriate for a wider range of inputs than standard plastic garden sprayers. Common applications in hydroponic and traditional growing environments include:

• Foliar fertilizer application: Spray liquid nutrients or calcium/magnesium supplements directly onto leaf surfaces where uptake is faster than root-zone delivery alone.
• Pesticide and insecticide application: Coat leaf undersides and stem junctions with insecticides or miticides; the trigger lock helps maintain consistent pressure over a full canopy pass.
• Herbicide application: The polyethylene tank resists breakdown from herbicide concentrates, making it safe to use for weed control in outdoor garden areas adjacent to the grow space.
• Plain water or pH-adjusted water: Use for rinsing runoff trays, misting cuttings, or wetting growing media prior to transplant.
• Cleaning detergents: The manufacturer confirms compatibility with cleaning detergents, making it useful for sanitizing grow room surfaces, trays, and pots between crop cycles.
• Solvent-free preservative treatments: Suitable for applying solvent-free wood or surface preservatives in and around the grow structure.

If you are also managing water quality in your system, the Dilution Solutions 1-1/2 in. filter with 200-mesh screen is a common pairing for pre-filtering source water before mixing sprayer solutions. For EC and pH monitoring of your foliar mixes, the Apera Grostar GS3-E replacement EC electrode can help you verify solution strength before application.
