Is hydroponics organic? This is the question I always hear... and the answer is yes and no. Growing organically is a method of growing and not an actual technique. What I mean is that a dirt garden and a hydroponics garden can both be 'organic' if pesticides and nutrients used to maintain the garden are not made with 'processed' chemical ingredients. So a hydroponics garden using a chemical hydroponics nutrient is not organic but one using seaweed and blood meal for nutrients is organic. As for a site focusing solely on organic hydroponic gardening, I honestly do not know of many and the few that I do are solely based on growing marijuana. Unfortunately these sites have the most information available on practical organic hydroponic gardening. Do a google search on 'organic hydroponics' to find a good site. The next question was whether the various garden teas made from compost and worm castings contain all the major and trace elements needed for growing plants in a hydroponics system. And the answer is 'yes'; these garden 'teas' have it all but they may be time consuming to make. And as for using aquarium water to fertilize plants it would probably not work. This method is called aquaponics and is successful in large systems but in small aquariums the amount of fish droppings needed to supply the required amount of nutrient to plants would be toxic to the fish. And I'm talking small aquariums here - 5 to 50 gallons. Something bigger may actually work.
