By monitoring temperature, humidity and light cycles, the controller calculates and maintains the ideal Vapour Pressure Deficit (VPD) for your plants. This helps create the optimal climate inside a grow tent or grow room, supporting healthy plant development, efficient nutrient uptake and improved yields.\u003c\/p\u003e\n\u003cp data-start=\"527\" data-end=\"952\"\u003eHumidity plays a crucial role in plant transpiration. If the air is too dry, plants transpire too quickly and can absorb excessive nutrients, leading to leaf burn. If humidity is too high, plants struggle to transpire and nutrient uptake slows, limiting plant growth. The Intelligent VPD Humidity Controller balances these factors automatically by regulating connected humidifiers based on real-time environmental conditions.\u003c\/p\u003e\n\u003ch3 data-section-id=\"ycgkk5\" data-start=\"954\" data-end=\"970\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"971\" data-end=\"1457\"\u003e• Automatically maintains optimal \u003cstrong data-start=\"1005\" data-end=\"1029\"\u003eVPD for plant growth\u003c\/strong\u003e\u003cbr data-start=\"1029\" data-end=\"1032\"\u003e• Controls humidifiers based on temperature and humidity levels\u003cbr data-start=\"1095\" data-end=\"1098\"\u003e• Built-in \u003cstrong data-start=\"1109\" data-end=\"1157\"\u003etemperature, humidity and light sensor probe\u003c\/strong\u003e\u003cbr data-start=\"1157\" data-end=\"1160\"\u003e• Separate \u003cstrong data-start=\"1171\" data-end=\"1206\"\u003eday and night humidity settings\u003c\/strong\u003e\u003cbr data-start=\"1206\" data-end=\"1209\"\u003e• Multiple control modes including VPD and relative humidity\u003cbr data-start=\"1269\" data-end=\"1272\"\u003e• Warning display if the humidifier runs out of water\u003cbr data-start=\"1325\" data-end=\"1328\"\u003e• Helps maintain stable grow tent and grow room environments\u003cbr data-start=\"1388\" data-end=\"1391\"\u003e• Suitable for hydroponics, coco and soil indoor growing systems\u003c\/p\u003e\n\u003ch3 data-section-id=\"1mcmyku\" data-start=\"1459\" data-end=\"1490\"\u003eHow It Solves Grow Problems\u003c\/h3\u003e\n\u003cp data-start=\"1492\" data-end=\"1797\"\u003eHumidity imbalance is one of the most common issues in indoor growing environments. Low humidity can cause plants to transpire too quickly, leading to nutrient imbalances and leaf burn. High humidity can reduce transpiration, slow nutrient uptake and increase the risk of mould during the flowering stage.\u003c\/p\u003e\n\u003cp data-start=\"1799\" data-end=\"2204\"\u003eThe Intelligent VPD Humidity Controller calculates the correct humidity levels based on air temperature and plant leaf temperature. By maintaining the optimal VPD range, plants transpire efficiently, allowing roots to draw nutrients correctly while preventing environmental stress. This balanced environment supports stronger vegetative growth, healthier plants and improved yields during the bloom stage.\u003c\/p\u003e\n\u003ch3 data-section-id=\"1qw4ccu\" data-start=\"2206\" data-end=\"2220\"\u003eHow to Use\u003c\/h3\u003e\n\u003col data-start=\"2222\" data-end=\"2820\"\u003e\n\u003cli data-section-id=\"2ylfr9\" data-start=\"2222\" data-end=\"2286\"\u003e\n\u003cp data-start=\"2225\" data-end=\"2286\"\u003eConnect your \u003cstrong data-start=\"2238\" data-end=\"2252\"\u003ehumidifier\u003c\/strong\u003e to the controller power outlet.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"fbn4ws\" data-start=\"2287\" data-end=\"2370\"\u003e\n\u003cp data-start=\"2290\" data-end=\"2370\"\u003ePlace the \u003cstrong data-start=\"2300\" data-end=\"2316\"\u003esensor probe\u003c\/strong\u003e at canopy height within the grow tent or grow room.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1ovy77f\" data-start=\"2371\" data-end=\"2430\"\u003e\n\u003cp data-start=\"2374\" data-end=\"2430\"\u003ePower on the controller and navigate to the main menu.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"6osycf\" data-start=\"2431\" data-end=\"2499\"\u003e\n\u003cp data-start=\"2434\" data-end=\"2499\"\u003eSelect the desired \u003cstrong data-start=\"2453\" data-end=\"2469\"\u003econtrol mode\u003c\/strong\u003e (Relative Humidity or VPD).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"14pjltg\" data-start=\"2500\" data-end=\"2640\"\u003e\n\u003cp data-start=\"2503\" data-end=\"2640\"\u003eIf using VPD control, measure leaf temperature using an infrared thermometer and enter the difference between leaf and air temperature.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1wbzdyb\" data-start=\"2641\" data-end=\"2699\"\u003e\n\u003cp data-start=\"2644\" data-end=\"2699\"\u003eSet your desired humidity or growth stage parameters.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1ysdo6d\" data-start=\"2700\" data-end=\"2820\"\u003e\n\u003cp data-start=\"2703\" data-end=\"2820\"\u003eThe controller will automatically activate the humidifier when required to maintain optimal environmental conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp data-start=\"2822\" data-end=\"2987\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eBy maintaining balanced humidity and VPD levels, the controller helps create the stable environment plants need to thrive throughout vegetative growth and flowering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e","brand":"Hydro Crop Shop","offers":[{"title":"Default Title","offer_id":52712562360586,"sku":null,"price":249.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/meters-sensors-global-air-supplies-intelligent-vpd-humidity-controller-30134424436920.webp?v=1773495832","url":"https:\/\/hydrocropshop.co.uk\/products\/global-air-supplies-intelligent-vpd-humidity-controller","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
