Syringes - Plastipak Graduated Syringes for Accurate Dosing
Best for: Growers who need to measure small, precise amounts of nutrients, additives, or PK boosters rather than eyeballing it with a jug.
Our thoughts
Cheap nutrient jugs and measuring cups are fine for whole litres, but the moment you're dosing a few millilitres of a bloom booster or additive per litre of feed, a graduated syringe is the only way to actually get it right. Grab a couple of sizes rather than trying to make one syringe do every job.
These are Plastipak graduated syringes, sized from 2ml up to 100ml, each marked with clear volume graduations for accurate measuring. They're designed for precise, small-volume dosing - exactly the situation nutrient additives, PK boosters, and root stimulants tend to call for, where a few millilitres either way can make a real difference to feed strength.
Available across five sizes to suit different jobs: a 2ml syringe with 0.1ml graduations for very fine dosing, up to a 100ml syringe with 10ml graduations for larger volumes where fine precision matters less but speed does.
How it compares
Syringes are simply a more accurate tool than the alternatives most growers reach for by default.
- Far more precise than pouring by eye from a measuring cup, especially for doses under 10ml
- Cheaper and more disposable than dedicated dosing pumps for growers who aren't measuring large volumes regularly
- Graduated markings give a clearer read than most jug or cup scales at small volumes
A small, cheap investment that pays off the first time you avoid over or under-dosing an additive.
Usage guidance
Choosing a size
Match the syringe to your typical dose - a 2ml or 10ml syringe suits small-dose additives and boosters, while 50ml or 100ml suits larger-volume base nutrients.
Measuring
Draw liquid up to the required graduation mark, checking at eye level for an accurate read, then dispense directly into your mixing water.
Cleaning between products
Rinse thoroughly between different nutrients or additives to avoid cross-contamination or unwanted chemical reactions in your feed.

Who this is for
- Growers dosing concentrated additives, PK boosters, or root stimulants in small amounts
- Anyone who's previously over or under-dosed by pouring straight from the bottle
- Growers running a full nutrient line where several additives each need accurate small doses
Our take
It's a genuinely small purchase that solves a real problem - guessing doses by eye is one of the easiest ways to under or overfeed a plant, and a graduated syringe removes that guesswork entirely. Worth having a couple of sizes on the shelf next to your nutrients.
Does exactly what it should, day in, day out, feed after feed.
