Hydroponic techniques were&nbsp; also used in the 10th and 11th centuries by the Aztecs to grow crops at Lake Texcoco, and references to hydroponics were found in the writings of Marco Polo following his exploration of China in the late 13th century.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Hydroponics is widely considered to be a more effective cultivation method than soil-based gardens because it allows water and other nutrients to be applied directly to the root \u2014 as opposed to soil-based gardens, where water and nutrients are absorbed through the soil. This allows roots to access the nutrients without having to \u201csearch\u201d through the soil\u2014which can result in larger, healthier plants.<\/span><\/p>\n\n\n\n<h2 class=\"wm-article-table-of-contents-header\" id=\"hydroponics-vs-soil\">\n\tHydroponics vs soil<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">There is a growing body of research suggesting that hydroponic agriculture is a more efficient and reliable method than traditional cultivation in soil. For example:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A <\/span><a href=\"https:\/\/pdfs.semanticscholar.org\/d138\/1ebcba5802c7d668d4940491857979e4a923.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"font-weight: 400;\">study published in 2015<\/span><\/a><span style=\"font-weight: 400;\"> compared strawberries grown in soil to strawberries grown hydroponically. This project found that, although soil produced the largest individual berries, the \u201chydroponic strawberries were higher in terms of fruit yield and plant survival rate.\u201d Additionally, the hydroponics setup also produced fruit that was more consistent in terms of size.<\/span><\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li style=\"font-weight: 400;\"><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4483736\/\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"font-weight: 400;\">Another 2015 study<\/span><\/a><span style=\"font-weight: 400;\"> concluded that hydroponics is a promising technique with great potential for high-efficiency agriculture. Researchers noted that there are still too many energy inputs required to make hydroponics significantly better than soil on a large scale, but suggested that technological advancements could fix this. At that point, large scale hydroponics agriculture would become much more efficient than soil-based agriculture.<\/span><\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A <\/span><a href=\"https:\/\/avestia.com\/MCM2018_Proceedings\/files\/paper\/ICMIE\/ICMIE_131.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"font-weight: 400;\">2018 study<\/span><\/a><span style=\"font-weight: 400;\"> showed that hydroponic agriculture has a higher growth rate than soil-based agriculture, and concluded that hydroponics could be a promising way to grow plants more efficiently than growing them in soil.<\/span><\/li><\/ul>\n\n\n\n<p><span style=\"font-weight: 400;\">Advocates of hydroponic farming argue that hydroponic techniques produce a better final products, as they provide much more control over the growing environment. Additionally, hydroponic techniques are often more efficient than growing in soil because they require fewer inputs and use only what's needed to feed the plant. There is very little\u2014if any\u2014waste, whereas growing in soil requires many more inputs and a much larger portion of those inputs (plant food, fertilizer, water) go to waste in the soil. At this point, the only real downside to hydroponics is that many setups are indoors, which requires a lot of energy for lighting and ventilation.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">When it comes to the final product, the hydro vs soil debate is a matter of preference. Some say that plants grown hydroponically are better quality because they were grown in fully controlled environments. On the other hand, many claim that plants grown in soil have a more complex set of flavors and tastes\u2014something like the \u201cterroir\u201d that wine lovers talk about\u2014that come from the unique environment in which a plant grows.<\/span><\/p>\n\n\n\n<h2 class=\"wm-article-table-of-contents-header\" id=\"what-is-hydroponic-cannabis\">\n\tWhat is hydroponic cannabis?<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Simply put, hydroponic weed\u2014often called hydro weed\u2014is cannabis grown using a hydroponic method. Typically, hydroponic weed is grown indoors in a fully controlled environment. This approach gives cannabis growers complete control over the plants' environment, which can produce more reliable crops, more consistent buds, and faster harvest cycles.<\/span><\/p>\n\n\n\n<h2 class=\"wm-article-table-of-contents-header\" id=\"how-to-grow-hydroponic-weed-common-hydroponic-techniques\">\n\tHow to grow hydroponic weed: Common hydroponic techniques<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">To grow marijuana hydroponically, it's important to understand the various techniques used by successful growers. There are many systems that fall under the hydroponics umbrella, since it encompasses anything that's soilless and provides oxygen, water, and nutrients to plants. With that in mind, this simple hydroponics cannabis growing guide outlines some of the more popular techniques:<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"font-weight: 400;\"><strong>Deep water culture<\/strong><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Arguably the most simple of all hydroponics systems, the deep water culture technique is popular with beginners or cultivators looking to keep costs low<\/span>.<span style=\"font-weight: 400;\">&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">In this technique, each plant is placed in a separate pot or container. Thecontainers are then placed in a tray and water added to submerge the roots. If the containers have the ability to hold water individually, the tray is unnecessary.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Nutrients are added to the water, which is kept oxygenated using air pumps, allowing the roots to remain submerged.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"font-weight: 400;\"><strong>Wick system<\/strong><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">The wick system is another hydroponics technique favored by beginners due to its simplicity. With the wick system, plants are placed into a container over a reservoir containing nutrient-filled, oxygenated water. One end of a wick, which could be constructed from any absorbent material like cotton or cloth, is placed in the reservoir while the other end is placed in the container. The wick acts as the delivery system, drawing up nutrients and water to feed plants.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"font-weight: 400;\"><strong>Nutrient film technique<\/strong><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Similar to deep water culture, nutrient film technique involves continuously submerging the roots of the cannabis plant in water. However, nutrient film-grown plants are placed in a \u201cplanting tube\u201d (typically constructed from PVC piping). Oxygenated water containing nutrients is pumped from a reservoir into the tube. The tube is placed at an angle, allowing the water to flow through the tube and soak the roots of the plant before draining back into the reservoir.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"font-weight: 400;\"><strong>Drip system<\/strong><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Drip systems are popular with commercial growers because they allow for better control of the amount and frequency of nutrient solution delivered to each plant. With a drip system, each plant has its own individual water jet through which the nutrient solution is delivered using a time-controlled pump. Any excess solution is then collected back in the reservoir through the recovery system.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"font-weight: 400;\"><strong>Ebb and flow\/flood and drain<\/strong><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">The ebb and flow system, also known as flood and drain, is unlike other systems in that it doesn't keep the roots of the plants constantly submerged in water. Instead, the grow tray is flooded with the nutrient solution. After the flooding, the nutrient solution is then drained back into the reservoir, exposing the plants to oxygen before repeating the process again.<\/span><\/p>\n\n\n\n<h2 class=\"wm-article-table-of-contents-header\" id=\"materials-needed-for-hydroponic-growing\">\n\tMaterials needed for hydroponic growing<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">While the materials will vary based on hydroponics system, there are a few materials necessary for all <\/span><span style=\"font-weight: 400;\">hydro weed operations<\/span><span style=\"font-weight: 400;\">, including:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Seeds or clones<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Nutrients<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Containers for the plants<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Potting medium (such as clay pebbles or coco coir)<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Grow lights<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Water pump<\/span><\/li><li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Aquarium air pump<\/span><\/li><\/ul>\n\n\n\n<h2 class=\"wm-article-table-of-contents-header\" id=\"ideal-ph-levels-for-hydroponics-nutrient-solution\">\n\tIdeal pH levels for hydroponics nutrient solution<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">One of the largest contributing factors to<\/span><span style=\"font-weight: 400;\"> successfully growing hydroponic weed<\/span><span style=\"font-weight: 400;\"> is the pH level of the nutrient-filled oxygenated water solution.
