This process is essential for the final result because the bigger and stronger the plants get, the more energy they\u2019ll have to produce<strong> great quality buds.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2023\/03\/germinacion-de-una-semilla.jpg.webp\" alt=\"seed germination\" title=\"seed germination\"\/><\/figure>\n<\/div>\n\n\n<p>Growth fertilizers are very important to provide plants with the necessary nutrients, always using only the dose recommended by the manufacturer as over fertilization can be fatal for the plants. Equilibrium is necessary in order to avoid <a href=\"https:\/\/www.gbthegreenbrand.com\/blog\/2-5\/?p=35517&#038;p=13479\">nutrient excesses or deficiencies<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_importance_of_NPK_during_plants_growth\"><\/span>The importance of NPK during plant\u2019s growth<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>NPK stands for <strong>Nitrogen (N), phosphorus (P) and potassium (K)<\/strong>. These three basic elements&nbsp; for the proper development of plants, cannabis included, therefore, it\u2019s important to emphasize on its distribution.<\/p>\n\n\n\n<p>During the growth period, plants need more nitrogen than phosphorus and potassium because it is the most needed element to create roots, stems and leaves. Providing cannabis plants with <a href=\"https:\/\/www.gbthegreenbrand.com\/41-nutrients\">fertilizers<\/a> rich in these nutrients guarantee a good quality yield.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Available_types_of_marijuana_growth_fertilizers\"><\/span>Available types of marijuana growth fertilizers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>1. Organic<\/strong><\/p>\n\n\n\n<p>An organic fertilizer is the one that uses natural ingredients, such as seaweed, earthworms, animal and vegetable remains, etc\u2026Feeding the plants with organic fertilizers is environmentally friendly and widens the amount of resources, which <strong>improves the final flavors<\/strong>. However, the plant takes longer to absorb all the nutrients and the process is less specific than using chemical fertilizers, which is a bit inconvenient.<\/p>\n\n\n\n<p><strong>2. Chemicals<\/strong><\/p>\n\n\n\n<p>These products have the exact amount of nutrients that plants need, therefore, it is very easy to control their growth. They are also easier and faster to absorb, which maximizes the yield. These qualities along with its affordable price make it understandably the <strong>most used type of fertilizer<\/strong>.<\/p>\n\n\n\n<p>On the other hand, it is easy enough to over fertilize the plant if the dose provided is not correct, which can delay the yield and even ruin the crop. Unfortunately, the heavy metals present in these types of fertilizers are harmful for the human body, therefore, the roots need to be flush at the end of the process to remove excess chemicals and make sure that the flavors don\u2019t have a negative impact on the flowers.&nbsp;<\/p>\n\n\n\n<p><strong>3. Bio-minerals<\/strong><\/p>\n\n\n\n<p>Bio-mineral fertilizers coincide in their composition with chemical ones, as both include mineral properties, however, bio-mineral fertilizers don\u2019t use chemical processes to make them, which makes them less harmful for humans.&nbsp;<\/p>\n\n\n\n<p>However, as these products still have heavy metals, it\u2019s important to flush the roots before harvesting the yield. These fertilizers are very easy to absorb and promote a fast, healthy and strong growth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_are_the_best_growth_fertilizers_for_cannabis_plants\"><\/span>Which are the best growth fertilizers for cannabis plants?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Crecimiento_Boom_by_Boom_Nutrients\"><\/span>Crecimiento Boom, by Boom Nutrients<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.gbthegreenbrand.com\/boom-nutrients-nutes\/4586-crecimiento-boom.html\">Crecimiento Boom<\/a>, by Boom Nutrients is an excellent bio-mineral growth fertilizer for marijuana plants.
