Some are beginners\u2019 systems which are handy as a little extra boost and don\u2019t require much care, and others are professional systems that measure the <strong>PPM of CO2 that it\u2019s in the atmosphere<\/strong>. Professional systems are more effective and efficient than beginner ones, but they also require more work, investment and attention.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-172090 aligncenter\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-scaled.jpg\" alt=\"Co2 for cannabis plants\" width=\"2560\" height=\"1643\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-scaled.jpg 2560w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-300x193.jpg 300w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-1024x657.jpg 1024w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-768x493.jpg 768w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-1536x986.jpg 1536w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-2048x1315.jpg 2048w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-1200x770.jpg 1200w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-1980x1271.jpg 1980w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2022\/05\/cloud-co2-symbol-on-blue-sky-background-planet-po-2023-11-27-05-16-30-utc-1320x847.jpg 1320w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<label for=\"ez-toc-cssicon-toggle-item-6a5a1a4bd44f8\" class=\"ez-toc-cssicon-toggle-label\"><p class=\"ez-toc-title\" style=\"cursor:inherit\">Contenido<\/p>\n<span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6a5a1a4bd44f8\"  \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.gbthegreenbrand.com\/blog\/how-use-co2-cannabis-grows\/#Ways_to_supply_CO2\" >Ways to supply CO2<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.gbthegreenbrand.com\/blog\/how-use-co2-cannabis-grows\/#How_to_introduce_CO2\" >How to introduce CO2<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.gbthegreenbrand.com\/blog\/how-use-co2-cannabis-grows\/#Using_a_dehumidifier\" >Using a dehumidifier<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.gbthegreenbrand.com\/blog\/how-use-co2-cannabis-grows\/#Step_by_step_PPM_Levels\" >Step by step PPM Levels<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.gbthegreenbrand.com\/blog\/how-use-co2-cannabis-grows\/#Prevent_CO2_from_harming_your_cannabis_plants\" >Prevent CO2 from harming your cannabis plants<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Ways_to_supply_CO2\"><\/span>Ways to supply CO2<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">All CO2 generators work in a similar way. They are connected to a <a href=\"https:\/\/www.gbthegreenbrand.com\/Co2-enrichment\/1818-co2-controller-with-probe-by-neptune.html\">CO2 controller<\/a> that will shut off the flow of CO2 once it reaches a certain level, and open it again when it gets too low. Of course some of them are more sophisticated and efficient than others. It is worth investing in a good quality one to guarantee good CO2 levels.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If all you have is a normal <strong>CO2 meter<\/strong>, you can still control CO2 levels by opening and closing a solenoid valve using a timer. (<a href=\"https:\/\/www.gbthegreenbrand.com\/Co2-enrichment\/1825-electrovalve-for-co2-bottles.html\">Solenoid valves<\/a> are valves that open and close with an electromagnetic charge). Regardless of the kind of system you use, knowing the PPM of CO2 in your grow room is very important.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_introduce_CO2\"><\/span>How to introduce CO2<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>To <strong>introduce CO2 into your grow room,<\/strong> start by using a silicone tube with an outlet near the bottom of each plant trunk. Alternatively, you can run a 2-meter tube around the grow area, with holes pointing towards the plants&#8217; centers.<\/p>\n<p>Since CO2 is a <strong>heavy gas<\/strong> that naturally settles downwards, it&#8217;s important to <strong>use fans to circulate the CO2<\/strong> throughout the room. This circulation helps ensure that the CO2 reaches the plants effectively, enhancing their absorption.<\/p>\n<p>Once the setup is complete, it&#8217;s crucial to use CO2 correctly. Specifically, <strong>CO2 becomes beneficial during the flowering stage<\/strong>, starting from the 21st day. At this point, you should <strong>adjust your air filtration system<\/strong> so that the extractor runs for only about 15 minutes per hour. Otherwise, if the extractor runs continuously, it would exhaust all the CO2, making your efforts useless. Additionally, <strong>use a timer to coordinate the CO2 controller and the extractor<\/strong>, ensuring that CO2 is dispensed only when the lights are on. Conversely, the extractor should run continuously when the lights are off.<\/p>\n<p>In summary, CO2 <strong>enhances plant growth<\/strong> by <strong>thickening cell walls and promoting rapid cell multiplication<\/strong>. Therefore, it&#8217;s essential to <strong>provide proper fertilization <\/strong>during this process. Without adequate nutrients, plants exposed to high CO2 levels may become <strong>weak, bend easily, and produce poor yields.<\/strong><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Using_a_dehumidifier\"><\/span>Using a dehumidifier<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">When using CO2, plants need a slightly <strong>higher temperature<\/strong> than usual, around 28-32\u00baC so that the water in the leaves can evaporate slightly faster and the plants can absorb the nutrients straight away. Basically, we want the plants to absorb the nutrients but get rid of the water fast. You\u2019ll need a <a href=\"https:\/\/www.gbthegreenbrand.com\/humidity-and-temperature\/205-cornwall-electronics-dehumidifier-10-litres.html\">dehumidifier<\/a> to lower the ambient humidity to normal levels. Once the temp is raised and your plants begin evaporating water, humidity levels will raise a lot.<\/span><\/p>\n<p>[ppgbo product=&#8221;205&#8243; language=&#8221;en&#8221;]<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Step_by_step_PPM_Levels\"><\/span>Step by step PPM Levels<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\"><strong>EC levels<\/strong> apply if you are growing the weed using an aeroponic\/hydroponic system. This means that the plants are growing using a<strong> nutrient-water solution and an inert growing medium<\/strong> instead of an organic soil rich in nutrients.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you want to measure the <strong>EC levels in soil<\/strong> you\u2019ll need to measure the water that comes out from the bottom of the pot once you\u2019ve watered. If more is needed you can add it in the next watering. If it\u2019s too high then the next watering should just be water on its own.<\/span><\/p>\n<h4>Day to day<\/h4>\n<ul>\n<li><span style=\"font-weight: 400;\">Day 21 of flowering: Begin with 800 PPM, and keep it at that even when the extractor isn\u2019t on.
