Bluelab Pulse Meter – Soil EC, Moisture & Temperature Sensor with Bluetooth App

See Inside Your Root Zone. Grow Your Best Plants.

Every great grower knows the secret to bigger yields isn’t just what you feed your plants — it’s what’s happening at the roots. The Bluelab Pulse Meter lets you “see” inside your growing media without invasive pour-throughs or time-consuming slurry extractions. In a single click, get accurate readings of moisture (MC), electrical conductivity (EC), and temperature directly from the root zone — then view, store and analyse it all in the Bluelab Pulse app via Bluetooth.

Stop guessing. Start growing with data.

Why Root Zone Data Changes Everything

Moisture tells you when and how much to irrigate. EC tells you how much nutrient is available at the root. Temperature affects uptake and microbial activity. Miss any one of these, and you’re flying blind. The Bluelab Pulse gives you all three — fast, accurately, and directly from the substrate — so every irrigation and fertigation decision is backed by real data.

The result? Less waste, healthier plants, and more consistent yields across every grow.

Make Every Plant Your Best Plant

Every grower has that one plant — the one that grows bigger, faster, and produces more. With the Bluelab Pulse Meter, you’ll finally understand why it performs better, and replicate those conditions across your entire grow. Whether you’re managing a single tent or a commercial operation, the Pulse gives you the root zone intelligence to make smarter decisions, every single day.
