Kees A 1,163 Posted October 16, 2020 Die teller telt alleen maar, toch? Je kunt niet aangeven 'ik wil 30 liter' en dat ie dan stopt. Quote Share this post Link to post Share on other sites
Buyuk 350 Posted October 16, 2020 Die teller doet enkel tellen en meten enzo. Ideaal voor als je wilt weten hoeveel liter je nodig hebt maar doet voor de rest niks. Quote Share this post Link to post Share on other sites
GanjaRanja 294 Posted October 17, 2020 (edited) What is VPD and VPD charts? 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. 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. Dew Point - important to keep track of the risk of condensation. Air Pressure - new feature, more information coming soon! We're planning on enabling the tracking of pressure differentials! 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. Why is VPD Important? You probably already know that VPD is an important thing to keep track of in your grow’s environment, that’s why you’re looking it up. But why is VPD important? Getting your VPD right will give you the best results in your grow. VPD influences five key things, that are all somewhat related. Stomata Opening As VPD increases, stomata get smaller. CO2 uptake As VPD increases and stomata get smaller, CO2 uptake gets reduced. Transpiration As VPD increases, the plant transpires (evaporates from leaves) faster due to the larger difference in vapor pressures between the leaf and the air. Nutrient intake at the roots As VPD increases, and transpiration increases, the roots pull in more nutrients. The plant is like one connected system of plumbing! Plant stress As VPD increases, there are more forces acting on the plant – from the leaves to the roots – and the plant experiences more stress. As you can see there’s a complicated tradeoff between VPD and a variety of factors. You can increase how much CO2 the plant absorbs, but reduce the amount of nutrition. You can increase the amount of nutrition, but also stress the plant more. VPD is a very powerful tool in the grower’s toolbox. To get the best results you need to find the correct VPD sweet spot for the plant’s stage of growth. Ideal VPD for Different Stages of Growth So now you know what VPD is, how it impacts plants, and how you can change VPD. All that’s left is to figure out how to use this information in your own grow. Ideal VPD, as a general rule for plant growth, is around 0.8 – 1.2 kPa (kilopascals). However, your plants have different needs during different stages of growth. You need to tailor your grow environment to the stage of growth that your plants are in. Below are some general recommendations, but keep in mind that these recommendations can vary strain to strain, and setup to setup. As always, observe your plants and tweak things accordingly. Ideal VPD for Clones Clones are baby plants, they can’t handle a lot of stress because they are still just trying to form roots. Target a higher humidity and VPD closer to the lower end of the general range. The ideal VPD for clones is closer to 0.8 kPa. Ideal VPD for Vegetative Stage In veg (vegetative) stage the plants are bigger and more robust. You can reduce the humidity in your environment to increase VPD. This will increase water and nutrient uptake, but you don’t want to increase VPD too much. This will cause the stomata of the plants to close, causing them to absorb less CO2. CO2 is particularly important in the vegetative stage, because that’s the main ingredient that plants use to grow large. The ideal VPD for the vegetative stage is close to the middle of the general range, around 1.0 kPa. Ideal VPD for Flower Stage In flower stage the plants are robust, but the flowers are sensitive to various issues. You need to avoid excess humidity. The ideal VPD for the flower stage is closer to the top end of the range, 1.2kPa – 1.5kPa. Edited October 17, 2020 by GanjaRanja Quote Share this post Link to post Share on other sites

Die cijfers lees ik in ale tabellen die je op het internet ziet rondzwerven. Maar nergens is een bron te vinden waar die cijfers op gebaseerd zijn. Tuinders houden voor bijna al hun planten hele andere cijfers aan. Voor tomaten bijvoorbeeld wordt 0.8 als ideaal gezien. Ook als ze vol vruchten staan. Zou zo graag eens een wetenschappelijke onderbouwing voor de cijfers zien die je in de cannabis grafieken ziet. 1 Quote Share this post Link to post Share on other sites

Kees A 1,163 Posted October 17, 2020 Artikelen is iets anders dan wetenschappelijke onderbouwing of onderzoek. Dat kan ik nergens vinden. Iedereen heeft het steeds over dezelfde cijfers, maar geen idee hoe ze er op komen. Ik zeg niet dat ze niet kloppen, maar ik vraag me af waarom de cijfers van cannabis zo afwijken van andere planten. 1 Quote Share this post Link to post Share on other sites
