How to grow marijuana indoors? That is what we call Hydroponic Marijuana. Hydroponics is the cultivation of plants by placing the roots in liquid nutrient solutions rather than in soil; soilless growth of plants. Growing marijuana with hydroponics is the practice of growing plants in either a bath or flow of highly oxygenated, nutrient enriched water. Growing marijuana hydroponically simply means that you grow the plants in an inert, sterile growing medium instead of in soil. Hydroponics introduces the water, nutrients and air to the roots through the growing mediums and since using hydroponics bypasses the web of roots and the energy required for the plant to acquire the nutrients you get faster growing plants.
There are lots of other systems to consider aside from hydroponics. One example is Aeroponic system, sometimes referred to as Fogponics, the roots are not suspended in water but hang in the air where they receive a nutrient-rich growing medium via misting. Another is Drip Irrigation . It is A great way to save water. Used throughout large outdoor farming systems to cut down on waste, small droppers are placed right next to the stem or roots of the marijuana in their pots within the medium. Next in line is the wick system. The Wick System involves no moving parts. This system can use a variety of growing media, but in all cases the nutrient solution gets released onto the growing tray and delivered to the roots through a wick. To follow is the Ebb and flow. As discussed above the nutrient solution floods a tray situated above the reservoir and then ebbs back into the reservoir in the process feeding the plants with their roots situated to the tray. Similar to the Ebb and Flow technique is the Nutrient Film Technique (NFT) but it is more circular. The tray above the reservoir is tilted and the nutrients fed in from the top and let to drain in a thin film down the tray back into the reservoir, it lets roots feed and have access to air. Next is the Sea of Green (SOG) and Screen of Green SCOG. These growing systems are used more by commercial operations where speed and yields are paramount but can be used in smaller home grows. The equipment is different and you need cannabis strains that are capable of flowering after a short vegetation period. And lastly is the Continuous flow or Top feed system. This is the system you often see pictures of. Using a 2″ or 4″ PVC tube with holes cut into the top at regular intervals for the plants to sit in a holder or pot. The nutrients are continuously fed down the PVC pipe over the root system.
