Plant Sprayer 2l
The 2-litre permanent pressure sprayer delivers fast, even coverage across multiple plants without the fatigue of repeated trigger pumping. Pre-pressurise the tank once and spray continuously until empty. Adjustable nozzle, transparent reservoir, and ergonomic design make it a go-to tool for any grow room or garden. For targeted applications on individual plants, the 1-litre hand sprayer is a compact alternative. Fast shipping to Belgium.
Plant Sprayer 2 Litre — Continuous Pressure for Fast, Even Foliar Coverage
The 2-litre permanent pressure plant sprayer is built for growers who cover multiple plants regularly and can't afford inconsistent application. Unlike trigger sprayers that build pressure with each pull, this model pre-pressurises the tank via a pump handle — delivering a consistent, uninterrupted flow from the first spray to the last drop. For precise, targeted work on one or two plants, the 1-litre hand sprayer is a more compact option.
Features at a Glance
- 2-litre capacity: enough to cover 4–10 plants per fill depending on canopy size.
- Pre-pressurised tank: pump once, spray continuously — no interruptions mid-session.
- Adjustable nozzle: switch between fine mist for full foliar coverage and a direct stream for targeted application.
- Transparent reservoir: monitor solution level and colour in real time.
How to Get the Best Results
Fill the tank with your diluted solution — always follow the manufacturer's dosage guidelines. Pump the handle 10–15 times to build pressure. Open the trigger and work in steady, overlapping passes at 25–35 cm from the leaf surface for uniform coverage. For foliar products like BAC Foliar Spray, even distribution is critical for efficacy. After each session, depressurise the tank, rinse with clean water, and leave the nozzle open to dry. Pair your spray routine with a x60/100 microscope to inspect trichomes and track plant development throughout the grow.
Timing and Safety in the Grow Room
Spray at lights-on or just before lights-off when stomata are most open. Never spray under a full-power HID or LED at close range — this risks light burn and leaf scorch. Stop all foliar spraying by week 4 of flowering to reduce botrytis risk on dense buds. For outdoor and greenhouse use, avoid spraying in direct midday sun.

What is the difference between a pressure sprayer and a trigger sprayer?
A pressure sprayer pre-builds pressure in the tank via a pump before spraying, delivering a continuous, consistent flow without repeated trigger effort. A trigger sprayer generates pressure with each pull of the trigger, which can fatigue the hand over longer sessions and produces a less even spray pattern across multiple plants.
Can I use the 2-litre pressure sprayer with concentrated foliar nutrients?
Yes — always dilute concentrates according to product instructions before filling the tank. The sprayer is compatible with water-based solutions including foliar nutrients, bloom stimulators, calcium-magnesium supplements, and water-based insecticides. Rinse the reservoir and nozzle thoroughly with clean water after each use.
How many plants can I treat with a 2-litre sprayer per fill?
Coverage depends on canopy size. For small vegetative plants, 2 litres typically covers 6–10 plants with full leaf coverage on the mist setting. For large, dense plants in flower, expect 2–4 plants per fill. The mist setting delivers the most efficient and even coverage per litre of solution.
When should I stop foliar spraying during the flowering stage?
Stop foliar spraying by week 4 of the flowering stage at the latest. Dense, maturing buds trap moisture easily, creating ideal conditions for botrytis (grey mould). After this point, focus on root-zone feeding only. If treatment is required for pests late in flower, use targeted spot application and ensure maximum ventilation immediately after.
