<p>Optimise <strong>nutrient uptake, water absorption & growth - </strong>harness your<strong> </strong><strong>humidity</strong> &<strong> VPD </strong>with a<strong> </strong>G.A.S Intelligent Humidity Controller & G.A.S SonicAir Pro Humidifier.</p>
<p><em>How?</em></p>
<p>Your VPD is the <strong>'drying power'</strong> of air - how much pressure it puts on plants to transpire. It's determined by what your humidity is, at a specific temperature. </p>
<p>To optimise your VPD, this controller determines and <strong>maintains your ideal humidity</strong>, based on:</p>
<ul>
<li>air temperature</li>
<li>stage of growth</li>
<li>plant temperature</li>
<li>light cycle (on / off)<br><br></li>
</ul>
<p><em>You don't have to worry about temperature fluctuations messing with transpiration. No other humidity controller gives you this much precision.<br><br></em></p>

<li><strong>VPD 24 hours</strong></li>

<p>This calculates your VPD - the 'drying power' of air - based on: air temperature, relative humidity & plant temperature. You will need to specify the stage of growth you're at, and enter a target VPD for each stage of growth. Your ideal humidity is calculated and maintained, based on this. </p>
<ul>
<li><strong>VPD Day / Night</strong></li>
</ul>
<p>During the day, the controller works as described in 'VPD 24 Hours'. During the night, instead of targetting VPD, your controller monitors & maintains a static relative humidiity. This is because plants don't photosynthesise and don't need to transpire at night. Instead, it's more important to keep your relative humidity low, to prevent mould.</p>
<p>We recommend going for: VPD Day / Night. </p>

<h2 class="bluefoot-entity">What's VPD?</h2>
<div class="bluefoot-textarea bluefoot-entity">
<p><strong>Plants constantly transpire</strong> - this is where they lose water. This process directly<strong> impacts nutrient uptake, translocation & ultimately growth</strong>. </p>
<p>To control transpiration, some growers focus on their humidity. A higher humidity slows it down, a lower humidity speeds it up. The problem is, at different temperatures, your humidity has a different affect on transpiration,.</p>
</div>
<div class="bluefoot-textarea bluefoot-entity">
<p>To really know how your humidity affects transpiration, you <strong>need to monitor your VPD</strong> (vapour pressure deficit).</p>
<p>Think of your VPD as the <strong><em>drying power</em> of air.</strong> It uses your temperature & humdity (%RH) to <strong>calculate the transpiration pressure</strong> placed on plants. <br><br></p>
<ul>
<li>A high VPD means the air is dry, so water leaves plants at a faster rate</li>
<li>A low VPD means the air is moist, so water leaves plants at a slower rate<br><br></li>
</ul>
<p>Remember, moisture moves from wetter areas to drier areas. The bigger the gap, the faster this happens. Kind of like how a drier sponge takes less time to soak up a spill then a damp one. <br><br></p>
</div>
<h3 class="bluefoot-entity">Target VPD:</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p><strong>Early Veg:</strong> 0.4 - 08 Kpa<br>Plants are young and don't have a strong root system to replace water lost through leaves - you want a higher VPD to slow transpiration. </p>
<p><strong>Early Flowering:</strong> 0.8 - 1.2 Kpa<br>Plants have more leaves and more roots, so you can go slightly lower your VPD to speed up transpiration.</p>
<p><strong>Late Flowering:</strong> 1.2 - 1.6 KpA<br>At this point, plants are well established. Extra water uptake is helpful, and a drier air temperature helps ward off pathogens and diseases (e.g. bud rot). </p>

<div class="bluefoot-textarea bluefoot-entity">
<p>This controller is designed for use with the G.A.S SonicAir Pro Humidifer.</p>
</div>
<h3 class="bluefoot-entity">1. Place The Probe</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p>Place it in the centre of your grow room, above the canopy, under any lights (the probe will need to sense whether they're on or off for day/night mode).</p>
</div>
<h3 class="bluefoot-entity">2. Connect To Humidifier</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p>Connect the controller to your humidifier using the male/male lead (included). </p>
<p>Plug your humidifier into a socket - the controller is powered by the humidifier.</p>
</div>
<h3 class="bluefoot-entity">3. Set Controller</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p>Everything is set using the large 'Menu' dial.</p>
<ul>
<li>Turn to the right to select menus and change values</li>
<li>Press to select or open menus</li>
</ul>
<p>When you first turn the controller on, you will be on the home screen:</p>
<p>1 Turn the controller to the right to show default settings</p>
<p>2. Press the dial to open the main menu</p>
<p>3. Turn the dial to move through menu items</p>
<p>4. Select items from the menu by pressing the dial</p>
</div>
<h3 class="bluefoot-entity">4. Probe Calibration</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p>The probe comes pre-calibrated, however you can recalibrate it to offset the temperature or humidity. </p>
<p>To do this, enter the main menu, scroll to 'probe calibrate' and select it.</p>
</div>
<h3 class="bluefoot-entity">5. Leaf Temperature Offset</h3>
<div class="bluefoot-textarea bluefoot-entity">
<p>There's an option to enter a 'leaf temperature offset'. This is how much lower your leaf temperature is than your grow room temperature. We recommend an offset of '-1' for small plants, or '-2' for bigger plants. </p>
