Pairs well with
Pouring nutrients by the bottle cap is a guess, and guesses add up over a whole crop. These graduated measuring syringes let you draw liquid nutrients, additives and pH adjusters straight to the line, so every feed matches the label. They come in 10ml, 20ml and 60ml and are sold one at a time, so you buy the sizes you use instead of a bag of 25. They are plain plastic syringes with a printed millilitre scale and no needle: a measuring tool for the grow room, not anything fancier, and priced like one.
Specifications
Grower's Tip
- One syringe per bottle. Write the product name on the barrel with a permanent marker and they never get mixed up.
- Keep your pH Up and pH Down syringes completely separate from your nutrient syringes.
- Pick the size your dose fills most of. Measuring 3ml in a 60ml syringe is far less accurate than in a 10ml.
- Read the dose at the front edge of the rubber plunger seal, with the syringe at eye level.
- Draw a little past your dose, point the tip up, tap out the air bubble, then push back to the line.
- Never mix concentrates together in a syringe or cup. Each product goes into the water on its own, stirred in before the next.
- Rinse in clean water straight after the feed. Dried nutrient salts make the plunger stick and the markings hard to read.
How To Measure Your Nutrients
Pairs Well With
Strong stuff that needs small, exact doses. Give it its own 10ml syringe.
pH Up by Growth TechnologyFor when the water runs low. Same rule: its own syringe, never shared.
Bluelab pH PenMeasure the dose, then measure the result. Tells you when the pH is right.
Trigger Spray Bottle 1LFoliar mixes call for tiny doses into a litre. A 10ml syringe gets them right.
Hydroponic NutrientsBase nutrients and additives from the brands we stock, ready to measure.
Frequently Asked Questions
Are these syringes sold one at a time?
Yes. Each unit is one syringe in the size you pick. Add more to your cart if you want one for every bottle.
Do they come with a needle?
No. They are needle-free measuring syringes for drawing and dispensing liquids in the garden.
Which size should I buy?
Match the syringe to your usual dose. A 10ml suits small additive and pH doses into a watering can, a 20ml covers mid-sized doses, and a 60ml handles base nutrients going into a larger reservoir. Most growers end up with a 10ml and a 60ml at least.
Can I reuse them?
Yes, for measuring nutrients. Rinse with clean water after every use and keep each one on the same bottle. Replace it when the markings start to fade or the plunger drags.
Can I use one syringe for all my nutrients?
No, not if you can avoid it. Leftover concentrate carries from one bottle into the next, and pH adjusters in particular should never share a syringe with your nutrients. At these prices, one per bottle is the easy fix.
Can I use them for foliar spray mixes?
Yes. Foliar products usually go in at small doses per litre, which is exactly where a 10ml syringe beats pouring.
Are they suitable for medical or pet use?
No. We sell these for horticultural measuring only.
