Product Information

The Bluelab Truncheon Nutrient Meter may have been designed for everyday use, but we guarantee that it’ll become your growing companion for life.

All plants need access to the correct amount of food (nutrients) so that they can grow and flourish. Over- or under-feeding your plants can result in the waste of expensive nutrient resources and plant health issues.

The simplest way to keep track of the amount of nutrients in your solution is to measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.

By measuring and adjusting nutrient levels, you’ll ensure that your plants are getting the macro- and micro-nutrients they need for superior plant health.

Tried, tested and loved by growers for decades, the Bluelab Truncheon Nutrient Meter is renowned as the best conductivity meter for measuring solution. This brilliantly simple, bullet-proof nutrient meter allows you to measure and adjust nutrient levels for optimal plant performance.

All our products are designed with growers, for growers - so you can be confident that the Bluelab Truncheon Nutrient Meter can withstand the knocks and drops that come with everyday growing. Designed and assembled in New Zealand from local and imported components.
