What Does the Pulse One Measure

  • Light – The Pulse One measures light using a lux sensor. Using the lux sensor you can easily see if your light came on when they were supposed to or if there was a problem that needs to be corrected.

  • Temperature – The temperature in your growing environment can cause a number of issues if it falls too far out of your plants preference range. If the environment gets too cold, frosting can damage plants. If the environment gets too hot, plant’s can be scorched. The Pulse One measures the temperature so that you always know that your heat is within an acceptable range.

  • Humidity – One of the most overlooked aspects of indoor gardening is humidity. Humidity levels can determine if your plants are thriving. However, the wrong humidity can put them at risk of developing mold or pest issues. If your humidity gets too low than you may find your media losing moisture very quickly, which can leave you with plants that dry out sooner than you are available to tend to them. Alternatively if your humidity gets too high you can develop mold issues, especially during flowering stage. Having your entire crop developing mold just before harvest due to a humidity issue can be the most disappointing experience a grower can go through. Pulse One easily keeps this in check.

  • VPD – helps you identify the correct range of temperature and humidity to aim for in your grow space. With VPD you can achieve the best results while avoiding pest and environmental problems. VPD also controls plant transpiration rates, stomata opening, CO2 uptake, nutrient uptake, and plant stress.

  • Historical Data – The real value of Pulse One comes from accessing historical data. Looking back on weeks of data about your grow room to discover where things went wrong or where you can make improvements in your growing process can be invaluable.
