Bluelab Explained – Be PH, CF & Temp Perfect

Your nutrient pH, CF & temperature are vital. Get them right, and plants perform. Get the wrong, and you’ll have problems.

• Target pH: 5.5 – 6.5 (ideally 6)
• Target nutrient temperature: 18 – 21oC
• Target CF: Depends on your water hardness and stage of growth

To get precise, easy nutrient readings there’s one brand to use – Bluelab. They’re proven performers and we’ve sold them for years.

Their moto’s success by simplicity – you don’t have to mess around with lots of buttons. Even calibration is simple – there aren’t any fiddly calibration screws - just a simple button.

All GroWell staff are certified Bluelab handlers – if you need help with a Bluelab product, get in touch.

There’s a reason why Bluelab products are bestsellers.

Most come factory calibrated and are ready to use straight away. When you do recalibrate, the recalibration button makes it easy.

All products are robust and reliable. As long as you look after them and maintain them, they’ll really last you.

Most products come with a 12-month warranty. The Bluelab Combo Meter comes with a 5 year warranty (6 month on the probe).

You can calibrate using pH 7, pH 4 & pH 10. Really, just pH 7 & pH 4 are enough to ensure your pH is super accurate.

To get precision pH readings, your nutrient temperature is taken into account.

Monitor & automatically adjust your pH with a Bluelab pH Controller.

To prevent over-dosing, there’s a dosing lockout feature.

The controller keeps your pH to within 0.5 pH of your target. It’s ideal for keeping your pH stable as plants consume nutrients.

You’ll find it easy to use with an on-screen guide. Simply set it up and forget about it, knowing the pH is taken care of.

• 14-piece kit (with replaceable parts)
• Automatic dosing (dosing tube included)
• Temperature compensation for accuracy
• Dosing lockout to prevent over-doing
• High & low alarm (e.g. in case you’ve run out of doser)
• Continues dosing following a power loss

Your nutrient temperature & pH go hand in hand. Measure both with a single tool – a Bluelab pH Pen.
