Measuring Cup - Accurate Small-Volume Nutrient Dosing
Best for: Growers who need to measure small, precise amounts of liquid nutrients or additives without guesswork or mess.
Our thoughts
It's a measuring cup - there's no clever trick to it, and that's exactly the point. Get the graduations clear and the size right for your dosing and it'll save you over- or under-feeding week after week. Cheap enough that there's no excuse not to have one by your nutrient bottles.
This is a small graduated measuring cup for accurately dosing liquid nutrients, additives and pH adjusters. It's available in two sizes, 30ml and 60ml, both marked with clear volume graduations so you can measure out exact doses rather than eyeballing a capful. The cup is made from durable, chemical-resistant plastic that holds up to repeated contact with concentrated nutrient solutions without clouding or degrading.
Accurate dosing matters more than it sounds - most bottled nutrient ranges specify doses in millilitres per litre, and consistently over- or under-dosing by even a small margin, multiplied across a feeding schedule, can throw off your EC and nutrient balance over a full grow cycle.
How it compares
A dedicated measuring cup is a small purchase next to a bottle of nutrients, but it's the difference between accurate dosing and rough guesswork.
- Compared with using a kitchen measuring spoon or cap-based dosing, a graduated cup gives a genuinely readable measurement rather than an approximate one.
- Against syringe-style dosing tools, a measuring cup is quicker for single-nutrient doses but less precise for very small volumes (under 5ml), where a syringe still wins.
- Most nutrient brands, from Canna to General Hydroponics, sell or bundle similar small graduated cups - this is a like-for-like replacement or spare at a low price.
It's a cheap, unglamorous bit of kit, but consistent dosing is one of the easiest ways to avoid nutrient problems.
Usage guidance
Using it properly is simple, but a couple of habits make dosing more consistent.
Measuring nutrients
Pour to the graduation line at eye level rather than looking down at an angle, which can make you misjudge the fill line by a few millilitres either way.
Choosing a size
Use the 30ml cup for smaller doses or concentrated additives dosed in single millilitres, and the 60ml cup when your feeding schedule calls for larger doses per litre of water.
Keeping it clean
Rinse between different nutrients or additives to avoid cross-contamination, especially when switching between products that shouldn't be mixed directly, like certain boosters and pH adjusters.

Who this is for
- Growers who currently dose nutrients by eye or with kitchen measuring tools
- Anyone running a multi-part feeding schedule where accurate ratios matter
- New growers building up a basic feeding toolkit
- Growers who want a spare or replacement cup for the bench
Best suited to anyone who wants their nutrient dosing to be consistent from feed to feed.
Our take
It's a small, cheap fix for one of the easiest mistakes in growing - inconsistent dosing. Worth having a couple around so you're never reaching for a random kitchen spoon.
Grab one in the size that matches your feeding schedule. At a price that makes sense, there's no reason not to.
