Hydroponics refers to the method of growing plants without placing them in the soil; this is why it is also known as the soilless method of growth. This method of growth can be used for several plants such as fruits, vegetables and herbs including marijuana. The plants that are grown using this method are usually placed in soilless mediums while utilizing the needed nutrients through a water mixture for their growth. This means that your plants will grow regardless of the medium they are placed as long as they have the required nutrients they need. By placing the plants in soilless mediums and only providing the needed nutrients in the water, you are eliminating the role of nature in their growth.
