What the lab checks for

11 parameters, each with its guideline

Guideline values follow the Hydroponics. Your results are shown against these, with the laboratory's exact wording kept alongside.

Parameter	Guideline	What it tells you
pH (pH units)	6.5–9.5	Acidity. Low pH can dissolve metals from pipework.
Conductivity (µS/cm)	2500 µS/cm	Overall dissolved mineral content.
Hardness (mg/l CaCO3)	No limit	Scale-forming minerals. Not a health parameter.
Iron (µg/l)	200 µg/l	Causes staining and discolouration.
Manganese (µg/l)	50 µg/l	Causes black staining and taste.
Nitrate (mg/l)	50 mg/l	Often from agricultural run-off into private supplies.
Phosphate (mg/l)	No limit	Plant nutrient. No drinking-water limit.
Boron (mg/l)	1 mg/l	Required for Scottish new-build compliance.
Cobalt (µg/l)	No limit	Trace nutrient; toxic to plants at high levels. No drinking-water limit.
Molybdenum (µg/l)	No limit	Trace nutrient. No UK drinking-water limit.
Silica (mg/l)	No limit	Dissolved silica; relevant to hydroponic nutrient balance and scale.

Everything you need to take the sample

Sterile sample bottles, sampling instructions, and packaging for sending your samples to the laboratory.

Taking the sample

Ten minutes, then post it the same day

Full instructions come with the kit. In short: sample first thing in the morning from the tap you normally drink from, fill the bottles to the line, keep them cool, and send them to the laboratory the same day in the packaging provided.
