Nutrient Film Technique ( NFT )
With this method , plants grow in a pipe or sealed buckets with the nutrient solution falling over the root base and returning to the main controller bucket in a 24-hour cycle , or timed intervals . Although this technique involves more adjusting ( one to four times daily ) of your nutrient solution ’ s pH levels to keep them in the desired range due to the recirculation of the growing system , it will offer faster root growth compared to stonewool and can be a great setup for stadiums , low-plant count , or ACMPR license holders wanting to set up a low-cost recirculating hydroponics method . Nutrient film technique is an excellent step into recirculating hydroponics and can be very versatile in how the systems are built ( piping , containers , hydroton rock , etc .). This system is diverse in how it can be built , which is why it was the first-ever recorded hydroponic setup built by the ancient Babylonians in the Hanging Gardens of Babylon .
Tree-Tech
The tree-tech method is a hybrid hydroponic technique combining the best of all four mainstream hydroponic growing styles . The nutrient solution is recirculated through a sealed , high-flow container system with intense air being delivered through a much lower water volume than deep water culture . The root growth is explosive due to the nutrients frothing up into the root zone like a beer . Plants grow extremely fast , and maintenance is lower than deep water culture or aeroponics . This method is great for growing large trees and can survive a power outage much like deep water culture . Water and nutrient consumption are reduced by 95 percent as opposed to soil , stonewool , or coconut-husk growing . This reinvention of the traditional hydroponic growing methods came from decades of hands-on experience . Offering the best aspects of the top hydroponic growing methods with a twist . It ’ s like a luxury spa for your roots , however , it does cost more than stonewool or nutrient film technique to set up . This system offers higher levels of dissolved oxygen for your roots than any other growing system .
“ Growing hydroponically is truly the only way to have complete control over your plant ’ s root system and what it needs , offering the largest , healthiest , and most boutique-quality yields .”
Deep Water Culture ( DWC )
Deep water culture is a system of buckets or containers with high-flow nutrient recirculation and aeration in every tank . Your roots grow into the oxygenated nutrient solution . Plants grow very fast in this growing system and it is excellent for licenses with low-plant counts to maximize production as you can grow very large plants . It does require more maintenance than some of the other systems as it requires regular pH adjusting and cleaning . Water consumption is reduced by more than 90 percent compared to soil , coco , or stonewool growing , but not as low as tree-tech or aeroponics . Deep water culture is a classic water-culture hydroponic method and is great for maximizing plant counts . You can fill a large area with a low a number of plants as it requires only a fraction of the plants you would need for a stonewool cube and slab method .
Aeroponics
Aeroponics house the root system suspended in air , inside a sealed container or pipe with the nutrient solution delivered to the roots 24 / 7 or periodically throughout the day . Growing plants in this system requires the least amount of water consumption out of all the systems and can offer very large yields due to the lack of any resistance on the roots . However , if you have a power outage and no backup power supply you will lose your crop very quickly due to the roots being suspended in the air . This method will also use the least amount of nutrients out of the bunch but will require the most maintenance . Aeroponics can be an excellent system for vertical farming when constructed in piping systems , being a smart alternative to the common closely stacked rack-style stonewool vertical farms and allowing more canopy space . Oxygen absorbs best into your water at temperatures between 64-66 ° F . It is important to keep optimum oxygen absorption while keeping a comfortable temperature for the roots . To ensure success , all recirculating hydroponic methods ( NFT , Tree-Tech , DWC , and Aeroponics ) absolutely must operate with a water chiller . It is recommended for stonewool or coco drain-to-waste growing as well but is not as crucial .
With a few simple key steps , anyone can jump into hydroponics and be successful . Keep low water temperatures to achieve a high dissolved oxygen level and avoid growing bad bacteria , use a low dose of clean nutrients , and keep your growrooms tidy . Saving time by automating your system allows you to keep the growing environment and system clean , spending more time with the plants and less time working . sponsored by
