When nutrients are added to water, they create the potential for electricity to flow — the higher the EC, the more nutrients are present. Monitoring EC regularly ensures your plants are getting exactly what they need to thrive, without the risk of nutrient burn or deficiency.\u003c\/p\u003e\u003cp\u003eSolution temperature is equally critical — water that's too hot or too cold directly impacts nutrient uptake and root health. The Bluelab Conductivity Pen measures both, so you're always in control.\u003c\/p\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":47985210360022,"sku":null,"price":140.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/6097\/9158\/files\/BluelabConductivityPen2.webp?v=1774498136","url":"https:\/\/growersdepot.com.au\/products\/bluelab-conductivity-pen","provider":"Growers Depot","version":"1.0","type":"link"}
